Electric Fan Control?
Waiting for OEM electric auxilliary fan, was wondering if the old 99's ECM controls it or just have the A/C clutch activate the relay? I dont seem to think the ECM sees or monitors A/C high pressure. Probably hook up manual switch for shut off at hwy speed.
Anyone done this install? open for suggestions.
