Re: FANS (and AC)

I think C1 and C2 wires are just ground signals to the Fans. I.e used to activate a low and high speed fan (fan1 fan2)

So thinking ......

Use the existing pinned C1 blue pinned 44 and associated relay to control main engine fan only. Basically come on and off as per engine temp and PCM tables.

For AC/condensor fan.
Just wire it with a binary switch like this.




Only downside is that the condensor fan will be on anytime the AC is on ..... even in highway speed traffic etc
