I got the fan switch installed and the hypertech powerstat, but how do i get the switch inside the car? like I didn't see any holes in the firewall.... should I drill a hole? does anybody have any pics of where there switch is? thanks

 

Disconnect the battery, then remove the PCM. There's a gromet on the firewall. I also removed the kick panel to make it easier to see.

 

what's the PCM? and what gromet in the firewall?
Thanks

 

pcm is up against the passenger side firewall and a gromet is a little rubber thing you can stick the wire through.
