There's the cold start injector time switch too.
It would help if we knew what you are trying to do.
jdub;1229458 said:The two stock fan switches operate well above those temps. One functions on @ 234 degs & off @ 225 degs. The other comes on at 212 degs & off at 203 degs. You will have to find an aftermarket switch to do what you want.

It does work off ground. I wouldn't use it to control an electric radiator fan though...a 180-190 deg on switch is a better choice. Once coolant hits ~210 degs, the ECU starts pulling timing.
