Need a stock 99-02 engine harness asap.
Post up if you have one.

Thanks,
Derek

 

might can get you one but it will be tuesday before i will know for sure...

i got a 2001 ls1 fbody harness????

 

That would be great buddy, I really appreciate it.

I have a 2002 Silverado with a Forged motor, turbo etc.etc.etc.
Im just now getting around to finishing this thing, I was going to spin over the motor to bukd some oil pressure and try to get her running tomorrow.

Heres my situation:

I have Bigstuff3 that controls my engine and tranny.

All I need is my gauges to work and for my starter to turn when i turn the key over.

I sent my stock harness off to have it modified by a company im not going to name just yet lol.

Well, today I hook up the modified harness which has no engine connectors. Just a starter wire, ground, speed sensor, oil pressure sensor, tach output wire for BS3 and a engine temp sensor.

Basically I told him to modify my old harness to just operate the gauges and spin my starter over.

Its all fucked up needless to say.
My starter wire has a constant 12 volts in the (run) position
No power to the gauge cluster at all.
etc. etc. etc.
I think he cut off a few too many wires lol.

Infact im sure he did, after looking at some of the PCM pinouts I see a couple that should be there that arent.

So, i need a truck harness to start over with.

 

Does it need the tranny plugs??? Sent you a PM

 

Item 18 is this users ad, it has the injector and O2's cut off it, but you shouldn't need them I'm sure he'd give you a good deal on it

derek, that SUCKS! hopefully that dude will refund your money or atleast buy you a new harness.

 

Thanks for the links and PM's guys!

Yes it does indeed suck lol, Ill get it done though. No biggie, thats why I love BS3. Its a self contained unit for the "big stuff" lol. Last thing I needed was a bad harness for the engine.

Thanks again!

Derek

 

i have a harness out of a 02 2500hd that had the 6.0/4l80e combo...it is drive by wire tb tho...it complete with the exception of 1 injector clip i think...

pm me if interested, i could be persuaded to part with it

 

Hey guys, I sorted out my problems with the modified harness. I went back and looked at all the pinouts in both PCM connectors and noticed the ground pinouts in the connector were not being used. After fixing this everything is working as it should.

 

thats good
