is there a way to do the mod to switch from low fan to off to high fan by doing the wiring in the relay area versus the connectors on the passenger side???that's my project for tomorrow...lol...

 

Much easier/better to do it on the wiring by the pcm, IMO.

 

ok....i'll do it there then...it's a 94 z28 and i had already done a mod that cuts the low speed fan on when the key is on but it still gets warm in traffic so i figured i'd do the other one to run high and low as i needed...thanks for the reply...
