TPI electric Fan HELP!
1988 tuned port injection setup with stock electric fan. i went out and bought a new fan, that does more RPM to keep the motor cooler. I noticed that on the stock fan it had a plug directly on the casing...i want to install the new fan so is it possible to just cut the stock plug from the harness and replace the plug with a new one?? like add the male end to the fan and the other plug to the harness? would that work? or is there something in the stock fan that it needs? Also.... is the stock electric fan good in irocs?? doesnt it turn on when the motor reaches a certain temperature? ive heard of people just re-wiring the fan to a switch so its always on, whats your guys' ideas/oppinons??????? :thumbup: :welcome: :P

Yes you can add the plugin onto the new harness. Just make sure you have the power and ground wires in the right places.

The fans are programmed via the chip to come on and off at certain temperatures. You CAN wire them to a switch but I really dont see much point as long as everything is setup properly.

ya i was just wondering about the switch thing, cuz i read somethin a while ago on a different site, and they mentioned a fan being hooked to a switch instead. Anyways thanks :)

I like to wire it to a switch and still keep the auto kick on feature. That way if you know your going to be heating up you can pre-turn the fan on. I have always thought that they wait too long to bring the fan on. When I had my celebrety the fan came on at 240 so I put a switch on it and at 200 I would turn it on. That way it never got to 240. But when my wife was driving and she never looks at guages it would still come on at 240 to protect the engine. I even tried to get a lower temp switch but couldnt seem to get one from the local stores.

When you get a chip burned for your setup, you can tell the guy you want the fan set to come on at a lower temp. Just make sure you run a thermostat that will compliment the newer temperature settings.
