I'll have another look tomorrow. I've had the whole thing bar engine and tranny off today to asses. Didn't see any rogue wires bar ones for a water temp display, could be those... snipped and linked up to the gauge in pod.
I'll take dash out, got some wiring behind there to do anyway. It's a monstrosity! I know it's going to be a track focused car but I don't want spaghetti mocking me while I drive
