Best Engine/Injector Wire Harness Options

2004 X 6.0L 4x4 Limited with 175k on the clock. Looking to replace engine and injector wire harnesses. A recent engine wiring survey shows signs of cracks. I currently have no issues, but I’m a preventative maintenance kind of guy plus this is one of the last things I need to do to complete “bullet proofing.” Since a lot of you have done this, was looking for replacement harness recommendations.

Unless it is beat up internally, buy some nice high temp harness tape, replace the expendable ends/pigtails that are questionable and run it.

Amazon

Last I heard it is really hard to find the engine harness and it is pretty damn pricey.

Good luck

I got mine off Rockauto about 3 years ago without any issues. A quick search for a harness for a 04, not sure which truck you have but RA has it for $283.99. Dont forget the 5% coupon.

The injector harness is readily available and inexpensive, but he also wants the complete engine harness unless I misunderstood.....that one is some cash and the one I decided to not replace and renew.

I wouldn't say it's inexpensive. Five years ago I paid $188.06.

Two and a half years ago my main engine harness was $455.44. I can only imagine what they are now....if you can find one. Best wishes on your search OP, and let us know what you find.

The injector harness is an easy one.
Engine harness = Hen's teeth.
They tend to be very hard to find this late in the game.
Good luck finding it.

One of the BEST reasons there is to keep engine temperatures down!

I've already found the harness. I'm trying to find out what in on the harness.

Amazon has part# 3c3z12b637ba for $209. I can live with that. My local dealer has it in stock for $385. Parts guy couldn't tell me what is on\not on the harness.

If you're talking about the injector harness, the only thing on it, besides the two FICM plugs and a ground, is the injector plugs, as the photo clearly shows. Not sure what the confusion is about.
