So I got some time to finish up the job this afternoon. I swapped the taillight jumper harnesses out with the new ones mentioned in my previous post above and everything is working as it should. Once again, I’m only using the audio portion of the BSM feature right now but plan to add new mirrors very soon.
if enough interest, I can try to tack on to the existing how-to guide with detailed steps of adding the wiring to the XY400 connector so that you do not have to drill a hole in the floor pan or splice into any wiring. its a pretty straight forward process if you read the attachment that Jimmy included previously, but I’d be willing to condense it to only the relevant information if anyone would find it helpful. Otherwise, anyone can just shoot me a PM and I’d be happy to help.
@Jimmy07 thank you again for the awesome wiring harness! First for the passive entry and now with the blind spot wiring! Amazing quality!
