I have my radio pulled out of the dash, it has a plug in the jack that would normally house the new one and a single green line coming out.
I got this cable
JVC KD-NX5000 KDNX5000 REMOTE /VIDEO IN/ OUT RCA CABLE *PAY TODAY SHIPS TODAY* | eBay
The pink speed sensor line from the above matches up to the single line in the existing connector so I guess my radio knows if I'm speeding
My plan is try to find the other end of that green line or otherwise adapt it so I can use the new plug and have the speed sensor and reverse signal (when I figure out what to tap), video etc all connected up..
Agree?
