Here are photos of the O2 wiring harness and pulled back the tape and sheathing. It is in bad shape. You can see the purple wires which has the jumper on the left. Any idea what year harness this is for?
On the O2 harness where it connects to the engine harness: 1) the wire colors do not match; and 2) on the opposite end of the jumper wires, the wires coming out of the engine harness are purple with yellow stripe and a yellow with purple stripe
