Engine is in truck and grounded. Thanks for all the help. Its cranking but I ran out of battery power for the night so ill continue tomorow. I cant figure out where this wire goes. I think its something with the glow plugs. Any help of location would be great. heres a picture. If the truck starts tomorow I will attach a video.

 

Looks like the power wire to the AIH but there usually is a nut crimped onto one of the eyelet ends...

 

Possibly off the starter or alt maybe. ??

 

You got it Greg it's the AIH!

 

Ground for AIH. You can see it in this pic. Goes from behind insulator over to driver's side plenum stud.

I think you are right. That makes more sense since it is a thin gauge black wire.

 

Yep I knew it was one of those extra wires in my shop box!...lol

Thats not the wire im looking for. Unless I have another wrong wire...i have the AIH wire. Its red and hat a nut on the end. Goes from the solenoid closest to you when looking at the engine and the post closest to you to the AIH. The wire I am looking at is black and navistar 1831651c1 REV-B 87694s1

 

The AIH should have 2 wires on it. One red and one black. The black goes on first as the ground. Look again at the image link, I posted.

 

Roland is correct. The heater needs a power and a ground because the spider is not grounded very well. The wire you have looks a lot like the AIH ground wire.

Here is another photo.

 

duh...thanks again!

 

Where exactly did the wire 1831651c1 go. Just rebuilt 2002 7.3L just need to find out where it goes.
