hello everyone,
i have a question about fanc.

my car did not had a stock fanc output, (no wire in A12)

currantly i have a wire going from pin A12 TO the green wire on the thermoswitch to activate the fan. is that ok?

or do i need a to wire separate relay.?

thanks,

 

What car?

Typically, as long as you tapped it to the correct side of the fan switch it should work fine. You're just adding another possible ground to the signal side of the fan relay.

Example:




And yes, you always need to make sure there's a relay.

 

thanks for the reply spadam, but if i tap into the the correct (green) thermoswitch wire isnt it already relayed? thanks

 

Yes, that's what I was showing you in the diagram.
