Injector engine wire harness

I'm trying to find a part number for the wiring harness that sits on top of the motor and plugs into the valve cover gaskets. The previous owner replaced the pigtails but the wires were cut so far back that there is virtually nothing left coming out of the harness. I have no idea what the actual harness looks like other than it has the 9 pin plug on it or whether both sides require an individual harness. If anyone has a part number or picture if said harness it would be most helpful.

Oh yeah....just in case.... it's a 2001 7.3.

Thanks!

That harness covers the entire engine from the 42 pin connector and connects to virtually everything on there.

oh yeah.....sounds like fun.....not really

The parts guy at the dealership is telling me it's only about 20 inches long and is easy. I'm thinking he's confused.

He may be just doing the connector + pigtail, as many of us do for ICP sensors.

I asked him if he was just looking at the pigtail and he assured me that he was not. I'm going to stop by and look at it just to be sure.

What did he quote for parts and labor? That would tell you if he is in the same ballpark.

Interestingly enough...that part is only for 02 and 03 7.3's. Says it won't work on a 2001.

I'm waiting for a response why as I'm told all 99-03 7.3s are the same.

Dealer parts guy wasn't paying attention to what I was saying....he pulls the harness out and it's the under-cover harness to the injectors and glow plugs. Still striking out.

If it's UVCH, that's GREAT news! Cheap and easy to do

That is one expensive puppy, if it was me doing the job I'd solder in some additional wire and use what I had.

yes it is but I'm growing extremely tired of having to plug this ....... thing.... in all the time to get it to start. As soon as I can find a garage to work in so I can feel my fingers and such, I'm going to unwrap everything and see what I have. If that harness solves my electrical issues then it would be money well spent.

UVCH connects to your glow plugs as well. If you are having to plug it in to start, then likely you need Under Valve Cover Harness AND Glowplugs.

GPs are about $80/set of 8. Use only OEM as some have had problems with the tips swelling or breaking and...bad stuff.

Make sure you are running fuel additive for the cold, too. Which one are you using?
