From memory it wasn't too hard to simply see which wire ran where when you plug that in.
Unfortunately also from memory the OEM sender does not use the same configuration 99.9% of gauges run. So in other words if you connect the signal wire that was running to the OEM gauge to your DEFI gauge you might find your oil reads at 200C or some other incorrect value.
I remember having the same line of thought and then running new wires/senders to match the gauges I have. The pinout is available in the R34 workshop manual.
Does anyone on here know which wire on the GTT triple gauge pod harness is for the oil temp gauge? my sensor works fine but I upgraded the gauges to DEFI advance. And if I can simply piggyback off the oem oil temp wire to the Defi oil temp sensor wire that would make life so much easier.
