I need help finding the wire that goes to the pin on the manifold near distributor...

Hey, everybody. I was wrapping my harness in wire loom and lost the wire that goes to the pin on the rear of the manifold next to the distributor. I assume it's a ground, but honestly have no idea what it does. I have one wire that could be a possibility. and it's grey and maybe coming from the ignition control module or ballast resistor. It's grey and is over by the passenger side bank of cylinders.

I'm a visual learner so some pics would really help me. If you have exposed wiring, that would also be a huge plus. Thanks!

I'm sure it's the oil sender HERE IS HOW you find out for sure

You don't want to short unknown wires to ground (or other places) so what you do is take a 12V test LAMP (not an LED) and hook between the wire and ground

Turn the key to run, and if you have an oil warning lamp see if it came on "dim". Look at your test lamp and see if it is lit. If you have a gauge, it should "come up" a little

When you ask questions here PLEASE post the year make and model

If you do not have factory service manual, wander over to MyMopar and download one, free. You may have to settle for Dodge vs Plymouth or vise versa
