HELP! Identify these wires 2003 5.3 harness I have a harness from a 2003 5.3 Yukon 2wd. There are some wires near the automatic transmission plug that were cut when it was removed. They are in a loom that comes out next to the bank 1 oxygen sensor 1 loom. I have spent too much time trying to eliminate all the known plugs and find these. You can see the transission plug in the pictures for reference.
