A couple months ago I got my car ref'd for my twin turbo engine swap (90 na 2+2 z32 shell with a 93 twin turbo engine). One of the problems with my swap was that my spal fan was not controlled by my ECU (as is shown on a stock 93 twin turbo 300zx). After talking to the tech from spal, he advised hooking up the grey wire, which originally connects to the coolant temp sensor, to the ground control for the cooling fan relay. My question is where and what does the ground control wire for the cooling fan relay look like?
