01 tahoe harness on my 99.
for the most part, 99-02 all work together (with minor differences) & 03-07 all work together (with minor differences).
the two groups have major differences between them.
I got a 2003 Chevy Silverado 5.3 harness For my 04
There are 2 little connects that don't plug up. Then there's 2 other a little down the harness that I can't find where they go. Then the fuel pump and gas gauge not working

Reason: Little 2 connectors are under fuse box
There is a odd plug called an EVO connector that goes to the back of some power steering pumps. Most don't use this connector, if it's like this and you have no connector on the steering pump let it ride. As for the other connectors a photo might help.

Doing a 2000 GMC 4.3 to 6.0 (LQ9) swap and hit a snag. The donor engine, wiring harness and ECM (12589463) came out of a 2005 Escalade. Just received an e-mail from Brendan Patten from LS1Swap and he confirmed the 2005 harness will not work with my 2000 fuse block.
If anyone is in the reverse situation and in need of a UNCUT 2003 - 2006 harness and ECU and wanting to swap (or has a 00-02 harness for sale) hit my PM. This is the only issue holding me from completing the swap. I'll list the harness and ECM in the classified section if someone is in need. I also have a used but clean DBW throttle body I won't be able to use.
I finally got the right harness. But the full pump is not working. They I turn the key to the start position and it will turn over, the i turn off and turn back to start position then it will not turn over have to turn off for a 30 seconds to a minute then it will turn over again. Please i really need so advice. My trucks a 04 and I got the engine harness off a 04. Feel free to message me on Facebook at Chris Williams i live in Louisiana
What's up guys i did my swap about a month ago , and it went fine except im having problems i think my motor is sitting wrong i got a v8 frame mount for coil springs like my truck but im not sure on if i put in a v8 mount on the passenger side. It seems like my motors to far over and hitting my steering shaft.
