Hi Rob,
been reading your old post about your coil wiring problem and would like to ask when Sal replaced your loom was it the whole engine bay to pcm loom and how much did it cost? any info on labour time would be helpful.
Reason i ask is the rear 3 coil plugs on passenger side showing no change to idle when unplugged so i'm thinking there is a break in the wiring after the first coil on that side.
I've had idle issues and was told it was plugged cats so took them off and it is better now found this.
The other possibility somebody suggested is without mil eliminators the computer has turned off voltage to those plugs?
please tell me what you think

Mark

 

Hey Mark how you doing Pal

I was VERY LUCKY and found my Harness used on E-Bay for like nothing,
think I got it for @50.00
give or take 10.00

I bought the complete engine harness



Sal put it in for a very reasonable price, and of what he told me although yes it's a PITA to do
it's really not too bad and you could prob do it yourself with no prob

Unfortunately Mark I dont know about mil eliminators and computer turning
off voltage to those plugs?

Hopefully someone can help there ???

 

Man Iam disappointed.............

No Wooooo-Hooooooooooo's
No @#$%%^^&*#'s
and only 1 picture

 

 

Thanks Rob,
guess i`ll start by pulling my harness and trying to make a repair, the chances of finding one on ebay are very slim and yes you were very lucky in finding one, although with the problems you`ve had with your trucks over the years u deserved a bit of luck!

i put mine back on when i put in the built motor...it takes some good time to try to lay it in there and hide as much as you can and make it as neat as possible. Before i put that back in my engine bay looked so clean and almost like a old muscle car engine bay....then it got ruined but still looks better than factory

 

Mark I wish I still had my old harness for you but I gave it to a brother a while ago (he soldered/changed/repaired all the coil wires + connectors on it)

I just searched a bit and your right they're not easy to find
Good Luck Mark and let us know how you make out

Kwilt there sure is a lot of wires to hide isnt there
Ah the good ole days.....

 

A friend popped the hood on his Toyota Tundra at work yesterday. He has the 4.7L. The engine bay is so clean, and everything is so accessible, that I had a moment of envy. It passed quickly.

 

 

There is alot of ENVY going on now

 

holey crap.

 

Well, after taking the time out to pull the harness and check the wiring for continuity it turns out the harness is fine and my pcm is fried!!!
What a PITA it was getting that m/f in and out.
Oh well, currently trying ebay to source a new pcm, anybody out there done this to give me idea of price?

Thanks
Mark

 

Dam V had a brand new one in the box for ya BUT "just" sold it
I'll keep my eyes out, I guess I can take the Lightning harness our of my favorite searches,
(I've been looking for you and there are NONE around, so good thing it wasnt.....)

But sorry you had to take it in and out to find out it was something else,
BUT glad you now know what it is
