Fan switch hooked up,Just One ?
I hooked up a manual fan switch according to directions, One BLK wire to Green/white wire from front relay, and other BLK wire from switch to Blue/white wire on back relay, works great, My question is, if I dont turn on the fans manually, will the computer still turn them on at the predetermined time of 228 degrees, thanx, Happy Motoring :cheers: :seeya

The ECM turns on the fans by grounding the gn/wh wire. You have merely paralleled a switch with the ECM, so if your switch is open, the ECM can turn on the fan as it normally does.

Yep. Although you have a 92, what's cool for L98 owners is that even without the Hypertech chip, when you use the replacement cooling wire to be used with 160 stat that kicks on at 200 and off at 185 it replaces the original wire(that may be worn anyway) and so it can be used with the manual aswell. When manual isn't in use..........it'll kick on like the wire's set for as usual.
