im not sure about the 90. but there should be a sensor on the bottom of the lower intake. there is a wire (yellow i think) with a red boot on it that is supposed to be hooked to this sensor, but if you just ground that wire instead of hooking it up to that sensor then your fan will be on whenever your ignition is on. take a look and lemme know what you see.

actually no. between the exhaust and the stereo I cant pick out a fan. plus my fan is from a pontiac sunbird and is not that loud. I've had my fan die on me and my car overheat before so I'd kinda like to know its running. Plus it doesnt help that I can only hear out of one ear.

sounds like your sensors are fine as well as your fans. take a peice of wire and run it from the wire that hooks to the sensor to under your streering wheel to a switch. then take a few inches of more wire and ground it to something close.
Also a good way to know if your fan is on with your stereo on is your volt meter might read 1 or 2 volts less. at least thats how i do.
