Does anyone have a diagram or access to tell me what two pins do on a RR4 ECU? Im running (or not running at the moment) a US ECU non HISS on my UK RR4 loom and I need to know what functions these pins do on the ECU There is a Green/black wire on ECU connector A pin number 25 and a Black / white wire on pin 29 on block B. I think one of these is a power feed.. Any help here chaps?
Should add the wires connected are on a US ECU, on the UK ECU these pins are not connected on the loom.
