I have a harness off a 2001 5.3 and there is a section cut off. Its where it y's off the 1st o2 sensor from the same strain of wires as the 4l60e connector.
Anyone know what it is. I did a continuity check and there are a few wires that go the pcm and a few that go to the firewall (connector)
Says its the Range Swith Siganls, powers, grounds...Is it a PRNDL or ?????


Some of the wires are
Wire------Connector
Grey------Red 62
White-----Blue 34
Blk/Wht---Blue 32
