Engine Wiring Harness - Large bulb type plug

After chasing a wiring problem with the alternator light, I came to this large bulb type plug on the end of the harness which feeds various sensors.  The large bulb type plug was disconnected when we received the vehicle several years ago.  Attached is the photograph of the bulb type plug on the left with the main power source plug disconnected at the fire wall on the right.

if any one knows what this plug on the left goes to, it is appreciatedhttps://ibb.co/GCFdX5k.[/URL]

Thanks,

Dan

reParkka,

Hemikiller may be trying to send you a subliminal message with the picture he posted.

that is called a anti=diesel solenoid for a reason, they really work !.

With the pic of the carb you posted, you may very well need to use one.

I don't remember any more if the ford bracket will work on the holley without modification, but holley makes a bracket for this purpose, as well as the solenoid too.

I bought my last solenoid from rock auto for uber cheap , if you have a local salvage yard they will be next to nothing, I have bundled and saved by adding these with other items.

Would hazard to guess that I have installed at least a dozen or so of these on hot rods over the years to cure engine run on, especially if you have to keep an idle at or over 1000 rpms and are past the idle transfer slots.

Nothing worse than seeing someone with a manual trans, having to stall the engine out by letting the clutch out in gear, oh wait , I forgot about the dudes with automatics.
