Headlight relays

Living in AZ and refusing to take my car out on rainy days (we don't have many anyway) I didn't think of a moisture factor. Our typical humidity level is 7-14%. Even with rain in the state right now we are at 21%. LOL.

I do remember their being a gasket on those headlights, but didn't see what it was made out of or how it acts when compressed. Have any more of that rubber sheet I turned you onto for the fuel tank gasket? ;-)

 Gasket material, not sure, I may have. It may be ok as is, but as our humidity is usually closer to 70-80% in Summer, something to consider I think.

Without any intent to hijack droptop73's post regarding headlight relays, I/we as per usual, have strayed a tad off course, from snow fall to headlight replacement with LED's. Well to continue a tad off course, today I received the Hella head lamps, which look pretty good. I received the Sealight H4/9003/HB2 LED bulbs a couple of day ago. I'm still waiting for the BLIAuto H4/9003 (same as Vspec brand Hemikiller listed) headlight wiring relay kit, which I may get tomorrow or Thursday. Once I have all of it, I'll install it. I did check the fit for the bulb and headlamps and no problem. I am however, a little concerned about moisture getting in as there is no seal for the LED's, only the Halogen bulbs (which will go into the glove box) That is something I'll look into, maybe a need to get creative. Pics to come.

Please keep hijacking this thread. This is all great information and has changed my planned direction significantly!

I need help fast. The relay harness you said you bought, is exactly the same I bought, but under a different brand name. The problem is it arrived this morning, but there were NO instruction with it. The ad picture shows a product manual, but alas, no manual. I did find a YouTube video with a guy installing this, or very similar harness in a Jeep. Not exactly the same, but it did show the basic connections. On the Mustang, I want to keep as much of this as possible hidden. I believe you have installed this harness, so my question is what did you do? I have taken a few pics with the harness just laid out approx. where I want it, I'll hide it behind the rad along the top of the rad support. The main issue will be connecting to the power. The wire supplied will have to be lengthened for sure. For connecting to the car's light harness, it has only one male plug so it has to connect as the pic shows and the other side will be left disconnected. Putting the lamps together and in is no issue at all as the instructions with the LED's is pretty clear. I will not be able to use the silicone covers and I don't want to silicone seal the (black) bulb holder to the lamp because of possible heat problems. I really don't think moisture will be an issue, so for now, I'm leaving the lamps as is.

Good call on leaving the lamps alone. I'm pretty sure that orange O-Ring has you covered. And the clamp on the Hella's hold the lamp base super tight to the back of the globe. Just make sure they low beam cutoff shade is orientated properly.

 If any moisture can get in, it would be around the edge of the black piece and the globe and  there is no ledge or anything that an O ring could be used. I don't think it will be any problem. Not only that, but the hole in the bucket is too small for the  seal provided, I may look at some other alternative, or not. AS far as the low beam cut-off, it only fits one way and as long as the globes are put in the car the right way up (reading the script), it should all be good. It's the relay harness that is the question. I don't want it visible if at all possible. To get the relays out of sight, I am going to have to lengthen or replace the power wire. It needs to be about 15-18" longer at a guess. I also would like to connect it to the Pos on the V/R, not the battery.

I think it will be fine as well. The clips on those Hella's keep the black piece super tight.

Hella H4 LED headlight upgrade with LED relay; UPDATE.

OK, I have figured out what is needed from watching a couple of good 'ol You Tube videos.

The kit I bought seems to be missing the product manual shown in the ad and a couple of zip ties. The way it was wrapped, I have to think it was a returned item and repackaged. I hope it works! No sign that it was ever installed, so my finger are crossed. I will notify Amazon.ca of this apparent fact.

All that is needed is to replace and lengthen the power wire to the fuse (which is only a 10 amp). I'll take some pictures of what I come up with, but the plan is to run the harness below the rad along the frame rail and mount the relay block as low as possible to the rad support in front of the battery. Any exposed wiring will be wrapped with harness loom tape (non sticky stuff). My aim is for this NOT to be seen and above all, replaceable back to original.

Now, time to go do it.

I "hid' the relays in the space between the rad support and the battery. This is what I have been using to wrap wires. I love it:

 I'm in the process of "hiding" the relay in the exact same place. As said, I need to add to or change the power wire with a more suitable connector. I am going to use the Pos terminal on the Solenoid where the battery cable connects. I think I said voltage reg. before, my error. As for tape, the stuff I have was from NPD and is glossy, like electrical tape minus the sticky stuff. What you show, is good to. 

I'll update soon, this won't take me long now.

Well, we live and learn. I just spent several hours working on installing and hiding the relay and harness as best as one can, only to find it did NOT work. The only change I made to the relay kit, was to install a longer power wire and that tested good at the fuse, which was also good. However no headlights working. So, cursing at myself for NOT testing it BEFORE installing, I disconnected the relay loom and reconnected the LED's directly and they worked fine. 

The package should have been a red flag in hindsight. It was just a grey bag. In the ad on Amazon, it showed a product manual, there was no such manual. I had to YouTube it. I suspect now, that this had been bought, found faulty and returned so some other poor bas*ard would have to deal with it again. I guess I'll have a cup of tea, then go rip it out again and send it back. I'm NOT a happy camper today!

On a positive side, I was able to pretty much hide everything so as not to look to out of place. Here's a couple of pics. If I reinstall another relay AFTER testing it!!! I'll do it the same way.

That sucks Geoff. Amazon has been getting way worse about sending damaged goods right back out into the marketplace. 

However, your headlights look nice and bright!!! : )

I have Rocketman's harness. And although I have not used it yet, it's an obvious quality piece, and he's a site supporter. I'd definitely recommend his product over an Amazon product.

 YES I agree. I'll for sure order from Bob after this "experience". Actually, I was not aware Bob made them, should have checked, but I was in a rush I guess. It was the same one under a different brand name, that Hemikiller used and he said his was good quality. I got a bad one without doubt. MADE in CHINA sh*t again!!

 YES they do. I'll run them without the relay for now.

BTW. Here's the real way to hide those relays. (And maybe force more air through your radiator at the same time). :classic_laugh:

Nice!, but I'm not going that far to hide the relays.

BTW, I have removed the harness ready to send back for refund. I tested for power 12V through the fuse to the relay block and that was good. As I'm not up on electrical stuff, I have to assume that if there is power going in, there ought to be power coming out, but no.. So, not going to piss around with this anymore. Time to talk to Bob aka Rocketman.

Bob's a very busy guy, probably won't answer his phone, so better to send an email or just buy the relay kit, you won't be disappointed!

That's the plan now. For me, the downside is paying in US Dollars plus shipping to Canada. Gets expensive. At least the LED's work without the relay, so the relay can be added on at a later date. I'm very disappointed the "made in China" pos didn't work.

I'd hold off until we hear some results back from John (jpaz) about whether the harness really made an impact at all with the LED's. They draw so little amperage compared to the old style headlights that it may not matter much.

 Chris, I was starting to think the same thing. I had no issues with the old Halogen lights, other than perhaps the relay would have made them brighter. I will check the cost of Rocketman's relay and as you suggest, wait for jpaz's results. (or yours)

The next thing I need to do is (when it's not raining) to check the aiming of these lights. I only did it last time against the garage door. I may pop over to my friends shop where he has the headlight aiming equipment. I hate being blinded by all the  (high up) SUV's and truck lights and I wouldn't want to blind anyone else either.

 For now, I have just put everything back together and tided up all the LED wiring.  I think that ends this little saga for now. I hope this has value for other members.

I do not have a direct comparison for this but here is what I did.  On my 71 Mach I converted to halogens FIRST with a Hella relay.  I got some crappy lenses (I mean they looked awful) but the halogens were noticeably brighter.  I rather like the halo LED look so I bought a pair of those and swapped them out but retained the relay.  I also put a pair of halo LEDs on the GT-351 WITHOUT a relay.  I did not see a noticeable difference between the two cars but i did not have them side by side BUT I did note I probably pissed off some neighbors in my subdivision driving around at night to check the adjustment (they were a bit high).  I do not think a relay is necessary in my experience if going to LEDs.  I have another relay for my vert that i already offered to a neighbor for his Camaro if he needs it

Bummer that the relays were bad. The harness looked to be of good quality with some random cheapo relays. For the $10 I spent, it was worth it to me. I bought mine with the intention of only using the wiring and swapping for a quality set of Bosch or Omron relays that are usually less than $10 each. 

I also had to lengthen the power wire, which I ran to the Batt (+) side of the starter relay. The wires were long enough to run across the strut rod crossmember with the factory harness. Relays were mounted low on the battery side of the radiator support in an existing threaded hole.

Thanks for replying. I see some differences on your set compared to the picture you posted of the Amazon ad. The set I got was just like that one, under a different brand name. The ground terminals were very thin and so were the male connectors. I was wondering about the need to ground both relays. I see your set has them joined, so only 1 screw needed. However, there was a ground wire connecting the 2 relays, so 1 screw would be okay. On the video I watched, the guy bolted to 1 relay, as I did. I don't even know if these ARE ground connections, or just a way to install. Anyway it's sent back and Amazon.ca have already refunded my money.

I installed my lights yesterday. I really like them! Got to try them on the road tonight and there is a big difference, much brighter than the halogens. I didn’t bother trying to see a difference between relay vs no rely, sorry didn’t have time. But I did take a couple pics of the halogens vs the led. Led on the driver side are brighter and whiter. Last pic is both sides led and I didn’t have the engine running. Very happy so far!

John, looking good. All I've been able to do so far is try them in a dark garage. It's been raining here, so I've not been able to get on the road to see how they really look.

Can you take a couple of pics of your wiring solution at the headlights. With the extended wire from the bulb and the driver, which I needed to zip-tie in place, looking somewhat original isn't really possible. I'm just wondering if you found a neater solution to mine. As for the relay, if you use it, can you post pics of your install for comparison.

Ok, here’s a few pics. I just hid the relay harness that goes over to the drivers side light up in the bumper. My relays are not hidden though. I did have them behind the rad support, but after I had the front end repairs done they put them on the front side of the support. I have been wanting to move them back but haven’t got to it yet. Other than that the connections at the headlights are behind the lights, so not to noticeable. I could probably tape up some of the new wiring so it’s not as noticeable too, but good enough for now.
