Adamw Posted June 11, 2023 Report Share Posted June 11, 2023 Can you make that question clearer. Do you have a grey plug ecu but blue plug engine loom or the opposite? The pinout for all our plug-ins are in the help file. Quote Link to comment Share on other sites More sharing options...
alsimports Posted June 11, 2023 Author Report Share Posted June 11, 2023 Hi my car has grey plug but RB25 non turbo but ecu plug not same pins as turbo car less ignition wires for coils not same place as turbo model Quote Link to comment Share on other sites More sharing options...
Vaughan Posted June 11, 2023 Report Share Posted June 11, 2023 A multimeter set to continuity and having a good look at wire colours should give you most of the pinout. Is your car 4wd or Rwd? Are you using the RB25de Neo loom on the RB20det? if so you will have to either run S2 coils (built in ignitors but same mounting as S0 coils) or you will have to cut off your engine loom to coil loom plug and wire in the igniter pack from the RB20det Series 0 motor.

alsimports Posted June 11, 2023 Author Report Share Posted June 11, 2023 Hi my car 2wd non turbo when checking my plug to turbo ecu plug there are no wires for ignition on ecu plug. When checking my main ecu plug for ignition coils no power no wires there on plug Quote Link to comment Share on other sites More sharing options...
Vaughan Posted June 11, 2023 Report Share Posted June 11, 2023 Can you attach a picture of your ECU plug showing where the missing wires are please Quote Link to comment Share on other sites More sharing options...

Vaughan Posted June 12, 2023 Report Share Posted June 12, 2023 Are you using the factory coils from the RB20det? Are you using the coil loom from the RB25de Neo? Quote Link to comment Share on other sites More sharing options...
