Both harness need to be connected-- the 4 pin supplies power to the unit and has the starter (and 1st ignition) wires, the other has the 2nd ignition and accessory (think blowers!) wires, as well as the brake wire, which is necessary for shutdown. You can program the settings-- instructions for doing so are in the manual. (Basically, once you've got it hooked up, turn on the car, hold down the valet switch for 10-15 seconds until you hear three chirps, push the valet switch 2-4 more times to get to the different programming menus.)
(All wiring info comes from
the 12volt's wiring database here. As always, you
must test each wire that you hook up to w/ a DMM before hooking up. Please do solder the connections. No cold solder joints, please!)
W/ that alarm (and it is an alarm, as long as you hook up door pin, and if you don't hook up door pin, you can't program it!) you'll hook up as follows
In the 6-pin and 4-pin plugs (mostly to ignition harness):
12 Volt (red) wires jumped together (leave a fuse on!) to White.
Starter (key side-- green) wire to key side of the cut BLACK/ white wire.
Starter (motor side-- purple) wire to motor side of the cut BLACK/ white wire.
(Can leave out green and not cut starter wire if you don't want starter kill/anti-grind.)
Orange to Yellow.
Pink to BLACK / YELLOW.
Pink/white to Yellow. (2 ignition wires because many cars have 2 ignition wires)
Orange to WHITE/ black (make sure is accessory, not starter!) (2 of my 3 sources think this is unnecessary...)
BROWN / red to GREEN / WHITE (above brake pedal in switch).
Blue/back-- probably unecessary.
In the 3-pin door locks harness:
Green to GREEN / WHITE, blue to GREEN/ red (both wires located in a 2-pin plug tapes behind the fuse box).
In the 22-pin connector:
BROWN / black to (I have conflicting information-- let your DMM be your guide) either blue w/ a relay or blue/red (relay not necessary?). If you find the blue wire that goes negative when you honk the horn, hook up the relay as follows: pin 85 to 12V, pin 86 to BROWN / black, pin 30 to ground, pin 87 to blue.
I would hook up the horn, else no auditory confirmation of lock and unlock, and it will be very difficult to program....
Violet/white to tach (blue wire in tach test connector [possilby by the battery?] or at the distributor)
Black white jumped to Green, both to Light GREEN/ red in the driver's running board. There will be two wires of this color there-- make sure you test! (and make sure you put the fuse in the low position).
White to RED / black by the fuse panel or in driver's kick. (make sure you put the fuse in the high position!)
Blue to GREEN/ black (above the fusebox in a blue plug). Only necessary if you want the alarm to monitor the trunk.
For defrost, you need to find the wire coming out of the defrost button that (hopefully) goes to ground when you press that button (and back to 12V after the defroster times out). Hook the blue/black wire from the 6-pin harness here (if you want defrosting to always happen in remote starts, which I think is reasonable). Otherwise, hook it up to one of your output channels, and you'll have to remember to activate it.
(Those are the 4 pin harness that's all pinks...)
Sorry if this is a little confused, I'm at home sick (which is the only reason I have time to give so much detail, but also means I'm a bit fuzzy-headed. Have I mentioned that you really need to check every single wire w/ a DMM before you hook up anything to it?)
