I still can't find the right "red" wire, but I'll try that again tomorrow.

the real problem I have is finding the right CANBUS connector -- the instructions say the third from the right -- but which side is the "right" side? It says to look for a brown/brown+black set in the fourth position, but in my car, neither "fourth" position wires (counting from both side) has brown/brown+black wires. they're all brown, or brown+red. there is one brown/brown+black, but I think it's on the end. So which one is right? Which side of the CANBUS connector is the "front"? Very frustrating.

Needless to say, I haven't gotten it working yet. I'll try again tomorrow or Monday.

See post #2 and #3 of this thread.

I'd recommend to use the ATO add-a-circuit (available at Pep Boys, AutoZone and the like) and draw power from the fuse box to avoid the guesswork in finding the right solid red wire. While you're at it, utilize the factory ground near the engine hood/bonnet release lever.

With the CANBUS connector assembly still seated in its place in the wire harness/loom channel. The right side is as you are facing it from the door, it's usually the side that has one or two unused CANBUS connection. If you have version 3 (be it 3.1 or 3.2), the flashing LED will tell you if you're in the correct spot or not.
