You have a few options here. (FIRST, DISCONNECT YOUR BATTERY!) One, you could splice these into your dimmer wire. I didnít know where this was & didnít feel like fishing thru the FSM to find it. Two, just wire it to a switched fuse in the fuse box. Or third, you can find the switched un-used power wire up behind the dash (sorta behind the stereo). I donít know if you can read the tag in the pic, but it says ĎSwitched Auxillaryí. I found this wire tucked up behind the dash, so I went this route.
I also tied in the power wire for the compressor to this wire. I ended up using a butt splice & duct tape Ďcause my new butane solder iron decided to take a crap on me.
Note: I know absolutely zilch about electrical, so if you end up frying something, donít blame me. So far I havenít set anything on fire, so Iím happy.
Now to start hooking up some air tubing to the controller. I cut (4) roughly 4Ē pieces & connected them to the back of the controller. The little cutter Rancho gives you is a great, I found a bunch of other uses for this thing, very sharp!
Now connect (2) Teeís. You may want to trim the inside tube a little shorter, that way your Tee will point straight towards the firewall. In the pic I didnít do that at first, but went back & trimmed it a little:
Youíll have a Tee for the Front & Rear, one line for the pump & one for the bleed valve for the F & R.
Now pop the hood & scope out where youíll mount your compressor & run your tubing. I donít have ABS so I already planned on putting it on the ABS tray, tons of room there. You will need to run (2) air lines thru the firewall to the controller. When you do this give yourself some way of knowing which is for the front & for the rear. I used masking tape w/ an F & R.
I ran the line thru the grommet where my hand throttle cable goes.
Hereís a shot from the inside (just above & to the right of the gas pedal):
I know it looks a little messy right there, but what I ended up doing & would strongly suggest is drill (2) holes thru the grommet for the air lines. It looks cleaner & thereís less chance of them kinking in the chopped up grommet.
At this point youíll want to run your power line for the compressor. Thereís two red wires, the longer one will run thru the firewall (thru the same grommet) & connect to the back of the controller. From the controller the shorter wire w/ the fuse (donít forget to put the fuse in!) will run to a switched power line, already told you where I tied in. Iíd eventually like to put in an auxiliary fuse box from Painless for this kind of stuff, but havenít gotten around to it yet (famous last words eh?)
After your power wire is run connect both air lines that will run from the compressor to the controller. You should also plug the bulbs back in.
Note: in the above pic I only have one power wire connected, & the bulbs are not shown.
Once youíre happy w/ your wiring & air line connections go ahead & mount your controller in its final location. You also may want to tidy up the wires & air lines. I used some small split loom that made it look pretty clean
