So, there is probably more than one way of getting this to work without a switch but this is one way that I did on my 95 GST.

1) Disconnect your battery (always when working on an electrical project to prevent ecu damage)

2) Locate your fusebox which should look like this:

3)Locate the radiator fan high and radiator fan lo relays (they are linked to ac fan high and lo as well)

4)Ground pin 1 on both high and lo relays
Note: Fan pins are located as follows

You can do it the way I did which was to run a wire from which sits between pin 1 and the relay to a local ground or make your own ground.

5)DOUBLE-CHECK ALL WORK! When youre positive that everything is done properly, reconnect your battery.


Hope this helps! Feel free to comment or leave feedback. Special thanks to luv2rallye.

Have you noticed any lower coolant temps? Did you have problems overheating before? It would be nice if you had a logger and could see if there was a decrease in coolant temps.
 
the prob. was before the fan wasn't kicking in when it should so the water temp would rise about 3 quarters of the way up on the stock water temp gauge. after i did this, the water temp sits a little under the half mark at all times... only difference i noticed is my voltage dropped by .2v. sorry no logger though
