Engine Wiring Harness

[gcbennet]

I'm swapping out my harness and bought a new one online. Compared NSN and p/n's and all was good. New one came in the mail with same NSN and p/n on the bag except it's not the same as either the one in my truck or the diagram in the TM. The one in my truck is an exact match to the TM. The new one is similar but missing leads 568A, 5A, 3B, 58B, 315A, 315B, and 315C. However, it has added 568, 315D, and a triple stranded, double-ended connector with leads 350C, 355B, and 359H at both ends, and a double strand connector tagged 349B and 359J. I can cut away the wrapping and splice/remove as necessary to build a good harness, but I'm wondering if I should even bother?

Here's some pics of the odd connectors.

I'd call and get your $ back. Im sure the harness you paid for wasn't cheap.

Ya, I've already emailed the seller and I'm just waiting to hear back. You're right, these are not cheap. Especially when you factor in the horrible conversion rate and equally horrible shipping costs.

If the harness has foil on it then it's for a 6.5 turbo engine. Else 6.5 na.

That looks like a 6.5 NA harness.
I have those type.

No foil on this harness. The vendor said he will check to see if he has the right one in stock and if so will replace it. The TM covers both the 6.2 and 6.5 in the harness removal and installation guide and this harness has completely different wires and connectors that aren't illustrated, and missing a few key cables and connectors as well. That said, I now have an NOS engine harness available...

It's a 6.5 harness...they can be used, but will require some mods..the GM type plug is the TPS on the injector pump for when using the 4L80E. For simplicity though...getting the 6.2 harness would be better to install.
Unless you upgrade to 200Amp setup...then that harness comes in handy.
