Best place for efan thermoswitch

My other question is that my Summit switch matches the diameter of the OEM switch but the threading is different. What about retapping that spot for the Summit switch and using the 200 deg switch to do both OEM and radiator efan? Can I use a relay to switch polarity to ground and have to go to my engine harness then also have the signal go out as intended to kick on my efan?

If everythign else in my post is correct and possible won't that have my idle kick up anytime either the efan or the a/c come on and also turn on the efan???

If that sensor is there, then you probably have the relay (or at least the wiring for the relay) that switches that fan on. Do you have the little fan on the front of your condensor? You can just use its wiring. You already have the FSM, but I'll post it for the others. To me it looks like the A/C control unit grounds the relay just like the switch does. I believe the idle control has nothing to do with this part of the circuit.



I used this adapter kit (10.99) to mount my gauge there. I believe its M16 or M14, which isn't NPT thread and required me to use an o-ring (same size as thermoswitch) to seal it.
