electric fan wiring help

[rideyamaha287]

ok guys i got done installng my turbonetics kit and my electric fan wont turn on i got rid of those bulky fans and put one electric fan. I wired it to the exsisting fan harness on the (driver side fan) and now it wont turn on. how do i wire it so it will turn on . if any one has had this problem please fill me in..?

Pretty sure thats the A/C fan on the driver side. Try turning the AC on and see if it turns on. If it does just wire it into the other fan harness.

nope im pretty sure the passanger side one is the ac one on the 420a. the driver side is the thermostat fan..

when looking at the connector with the clip on top, the left connection is positive and the right is neg.

I think you probably just connected the fan to harness incorrectly. There are at least three wires going to the stock fan; ground, power for high speed and power for the low speed. If you only connected the fan to ground and power for the high speed, yet the ECU is only signaling the fan to run at its low speed, your fan obviously won't turn on at all. My solution was to connect both power wires for the high and low speed together...

run the wires direct to battery and u can get a switch from Autozone

Or you can use a proper fused electrical system with ECU control, such as provided by the factory.
