Awesome 4 year old thread!!!
I have a 14' 428ix with Sports line. I'm looking to retrofit Rear PDC and just waiting for the retrofit that should be here by the first or second week next month.
I'm doing my research while i'm waiting. I picked up REM after confirming my REM doesn't have the 12 pin for rear PDC. I picked up this REM Part #61359866978. (

Would anyone happen to know if this REM pin out and wiring colors are the same as the 700 that has been mentioned in numerous posts?
Thanks in advance.
