I just purchased a 73 convertible.  I am going to install a Mach 1 grille but I need the 2 aluminum bezels that go around the headlights.  Any help would be appreciated. Thanks Mark  

Hi Everyone, I haven't posted in a long time.  Too much work, too many cars and not enough money.  I have just purchased the convertible.  Its been stored in a local metal building for the last 30 or so years.  I saw it about 20 years ago but the owner wasn't ready to sell.  Finally convinced...

Ok. I didn't know they cross matched wiring harnesses between the cars.

Hi Everyone,   I'm re doing the interior and noticed that the underneath driver seat I have three wire connectors.  Two are green plastic and connect together so no problem.  The remaining wire is brown but I don't see another connector to connect it to.  What does it go to? The Mach 1 has the...

Hey everyone,  sorry for the slow update.  Life keeps getting in the way of my Mustang time.  It appears to be the temperature sending unit.  I purchased a Motorcraft brand about a year ago.  I purchased the best NAPA has and so far so good.  I talked to the company that re built my gauges about...

Hi Everyone, I finally decided to fix my rusting vinyl roof on my 73 Mach 1 after waiting for my body/paint guy to have time which never happened.  After I fix the rust does anyone know what material/paint the factory would have put on the metal?  The previous owner replaced the vinyl top...

Thanks Don.  I will check my connections and ground.  If good then the sending unit is the problem.  I put a new one in about a year or so.

Hi Everyone,  This temperature gauge might take the cake as the saying goes.  My Mach 1 has the original  wiring and gauges.  I had them rebuilt professionally about 5-6 years ago.  Engine runs cool and spot checking with temperature gun it appears to be right on spot.  I replaced the...

Bump...I'm still trying to figure out what the large yellow male plug goes to? Any insight would be appreciated. I have reviewed the wiring diagram and still can't figure it out. Thanks Mark

Thanks everyone for the replies.  I did find my wiring diagram book.  I will travel out the pinkish color sure to see where it starts.  Midlife was correct I believe I had the Tach bypassed to prevent it going bad and shutting the engine down. Does anyone know the the yellow rubber male plug...

Hi Everyone,  I have 2 wires right above the brake pedal that just hang there. I don't know if they should be connected. One is the pinkish color with 3 female plugs. The other one a red sliced with a black wire. It has a large yellow rubber male plug. My question is what are the 2 wires for...

Great idea. Mark73Mach1 = Mark

OK I will start there Thanks

I just had all my dash gauges re done and calibrated. Kept the same circuit board and instrument voltage regulator. All gauges work great but when I plug the console clock wire to the wire harness the clock did not work. It was converted to quartz movement about 13 years ago and always work...

Thanks Don. What would be my cost on the window regulators and shipping? My zip in 80111 Thanks Mark

Hey Don, I am looking for both window regulators and the ram air motor actuators. Do you have some or know where I can find them for my 73 Mach 1. Thanks

Yes that is what I meant lol. Long day at work. Brain not fully engaged. I found it in the 73 wiring diagram. Thanks again

Randy, do have the wiring scheme for a 73 Mustang Mach 1 AM/8 track? Thanks

Thanks. So is there any harm in disconnect it so the new speedo cable can be installed?
