r32skizzzaaa Posted September 26, 2016 Report Share Posted September 26, 2016 Wiring a extreme into factory r32 skyline engine loom using the very short a and b loom. Is it OK to join the 4 wires into the group earth component by factory ecu plug on loom or better to extend and run the earths sepereatly to engine. Have been following the plug in wiring diagram, it says connect to a pin on ecu plug (can't renember number) but that little earth wire seems way to small to join 4 wires to. Please help me out cheers Quote Link to comment Share on other sites More sharing options...
Scott Posted September 27, 2016 Report Share Posted September 27, 2016 Hi, we recommend connecting each black ground to different locations. One reason for this is that if your earthing bolt comes undone the ECU will still have a good ground supply. The recommended places for grounding are the engine block and the chassis, the main thing is to make sure there is low resistance.Scott Quote Link to comment Share on other sites More sharing options...
