Hi guys, just bought a Rav4 03 model 5Door. Picked up really cheap as the previous owner end up with it in a ditch and damaged the front end. Replaced most of the part but, I end up with a spare plug and I was wondering if someone could help me to identify where is coming from. Looks like it supposed to go somewhere near the aircon condenser, passenger side and is part of the horn wiring loom. All I can think is it could be a sensor on the ACC line that it throw away as it was busted, but didn't took any notice what was on the line as i was 100% sure that i can find one on eBay or wreckers, but I got no luck with it.
