step 7) since 3 of my wires didn't run thru the firewall I had to add them. I didn't want to dick with the fancy CAT connector anymore since they were hard to get to and I didn't know what I was dealing with there. So I cut the 3 wires I needed on the engine side, and spliced in 3 new wires. I drilled a 1/2" dia. hole thru the firewall, just above the other 2 big connectors, and ran the new wires thru that.
to make sure that metal edge doesn't wear thru the wires, I made a little tube out of some of that rubbery stuff you line kitchen cabinets with and passed the wires thru that at the hole. Glued it up there so it shouldn't move away.
Not too many pics at this point cause things all happened fast!
step 8 ) run those 3 wires up to the dash where you will be connecting your switches.
step 9) Find your 4th wire (the common wire from pin #5) somewhere on the interior and splice in. I had a lot of extra length of wire at the TPS, so I made my splice there. Group that new wire in with your other 3 up at the dash.
step 10) you need a lead from that common wire to both switches, so make a jumper wherever is easiest
step 11) wire in your switches. Can be a pain depending on how your switches are set up and how much of a perfectionist you are. Getting the CC to work right was easy, getting the CC to work right and the lighted switches to work/function the way I thought they should function (indicator light on CC on/off switch only on when the switch is set to on) was a different story. but anything is possible with beer and infinite time.
my switches had the control lights in them as well, that part of it was super easy to get. my bus actually had 2 sets of extra wires for this behind the instrument panel. All I had to do was connect them.
while wiring up the switches the dash lights will work whenever, but the CC wires are only hot when the engine is on. So for verifying things are put in correct you need to start that puppy up. with the bus running I was able to test out the CC while parked by turning it on then fiddling with it. I think the ECM treats it the same as an idle speed adjuster when the parking brake is set.
the right side of my instrument panel was pretty crowded, and the left side was completely blank. So I took that metal plate off, went inside and took a dremel to it. Slapped some spray paint on it and I don't think it looks too bad.
step 12) sober up
step 13) take the bus out and really test your handy work. pull up next to a pretty lady (or dude, IDC) at a stop light, give em a little smile, and tell em what you just did with your brain and brawn. Perhaps a new friend, perhaps more than that.. depends on if you washed up during step 12 I suppose
long winded. hopefully this helps someone else out. thats all
