I wired mine...

alternator power 1 into 2 (both fans), then fans ground to thermofan switch, then thermofan switch to alternator ground...

and it works excllent... I could prolly use an inline fuse just off of the alt power but I haven't yet...

the only good power under the hood of my car that I know of is that alternator power because my main battery power wires are now hooked up just under the starter motor..

I had to get the air filter housing out of my way a bit to get to that thermofan switch but it wasn't that difficult..

I just figured id add a successful hookup to the end of this thread for anyone who reads this down the road trying to do the same..

thanks all for the help..

edit: thermofan, not thermotime...

Thermotime switch is intended to operate the cold start injector.

Are you sure you have described your setup accurately?

I have my fans running full-time. No switch needed ===> just turn on the AC fan and they will run! PS I know its cheap and easy to replace the thermo switch, however, cracking the radiator wasn't worth the risk for me.
