I just verified this on mine. MY setup: R33 S1 RB25 + DiF fan controller.

SIGNAL wire is the purple, Ground is Black with Blue stripe.

Yes, the two-wire coolant temp sensor that goes to the ECU. Not the single wire, (which goes to your instrument cluster).

That is all for stock, unless you changed something..

Capiche?
