2003 Tahoe Complete Wiring Harness

[reath1]

Ok folks. I've been battling the dreaded P2135 code in a 2003 Z71 Tahoe for years. Changed everything I've read it could be except the actual complete harness.

I'm at that point now. I'm having trouble locating the OEM part number or a suitable aftermarket COMPLETE harness. From ECM, TAC module, TPS, Injectors all the way to the ECM.

Can anyone point me in the right direction?

Thanks

You have the part number, so you could search other sources.

Try calling a dealership parts department and asking them to do a nationwide search on their system.

Did that for some obscure parts for a Buick Reatta. Ended up sourcing some from a dealership in NE.
