Hey guys,

Can someone with a bit of electrical knowledge tell me if something like the thermostat switch linked below could activate the engine fan(s) without causing any issues, ie with the ECU if both the ECU and this switch attempts to run the fan simultaneously?

Background info: Would like the fan to come on in the event that the ATF fluid temps spike. Car is fitted with an external ATF cooler but this is for traffic driving and/or just a precaution.

Thats the missing piece to my puzzle just what I needed to get my fan hooked up for my transmission cooler

Well I'm glad to be of assistance lol

If you haven't bought a cooler yet you can get ones that have fans on them with these thermostat switches.

Ive got a mishimoto one in storage ive just gotta work out whether my transmission in the car is stuffed or not before I fit the cooler
