Guys, what you're talking about is a good way to go, but you have to find that wire first. There's a bunch of them to choose from.


Which route are you talking about? There is only 1 wire going to the compressor. It's not hard to find. It comes right off the clutch and connects to the harness with a single bullet connector.

Then you'll be bringing high amps thru the firewall and looped thru a switch in-cab, which is not a good idea.


What is your idea of "high amps"? My A/C compressor fuse runs both the compressor and the internal solinoids that control the vacuum that opens the doors. The stock fuse and what is listed on the cover is 10amps. That means that the actual load on the system is less than 10 amps... probably around 6 or 8 amps. That wouldn't hurt anything coming through the firewall with a switch.

Also, if you don't buy a switch that is undesized, even if the compressor drew 20 amps, if you use a 30 amp switch, you would be fine. If you use a tiny little Radio Shack 1amp switch, yes, you will have problems... but if you use a switch designed for the type of load that will be handed out, you won't have a problem.
