Im installing a e-fan and i am confused as to which one of these is the thermoswitch to tie into. Thanks.

 

#1.

 

Alright good, the other one would of been a PIA to splice into to. Thanks!

 

If this is on an automatic NA, that will be a 195F switch, which is a lot more useful than the 207F turbo version. If you have the turbo one, I'd suggest finding the lower temperature switch, or getting an aftermarket one to use in its place. I used that same location for my SPAL fan controller's thermo-sensor.

 

this is a N/A 5 speed.

 

#2 is sender water temp..


by the way...this weekend i put my E-fan from BMW (bosch)

 

I wouldn't splice into that one anyways,as it tells the Ecu what temp the water is,so it can compensate Fuel.
THAT little sender there is one of the Things to check if you are Hot Starting/Flooding when cold.If it is Shot or Disconnected then it will give the Engine more fuel and when you start HOT,then it Over Fuels the engine and them you have to deflood.

 

Im alittle confused about which one now. Is #1 one ok? If not where is the correct one? just looking for a straightfoward answere. I wanna get this done tonight.

 

Lol.
Its #1 period.

 

thank you
