I have a 2012 RS with an older MXL dash that does not have the ability to add the AIM shift light module. I have a Cartek shift light module on its way and am trying to figure out which wire from the Life ECU to the MXL dash is the Tach/RPM feed so I can tap in to it for the shift lights?
I found a wiring diagram online and it looks like it is the wire going in to pin 8A on the 12 pin connector at the MXL is RPM but wanted to see if anyone has more info or has done this install before? Or can tell me which wire color combo it is?
Thanks!
