The reverse light harness on my car seemed to be a little messed up. One end was completely wrapped in electrical tape. So I bought a new repop harness and started removing the old one. Turns out, for some reason this harness was in between the transmission and the stock 4 speed harness.
As you can see each end has 3 connectors, but my transmission only has 2. On the end without a connector, the 3rd wire was bent down and taped to the other wires. I ended up just removing this and connecting the correct original harness back to the transmission. Everything is working great. Any idea what this would have been for?
