My car has 3 ignition wires and my R/S has built in for 2. Can I just hook a relay up to the third wire the same way I would for a second on a normal R/S?

Why not? As long as it powers up when it is supposed to

Sounds like a Chevy?

If your RS says the Orange wire on your RS is Accessory: Yes connect to Brown because that is the last wire (Orange) that powers after vehicle has cranked & started
So your New Relay would go to White at ignition switch

On your 97 grand am the only wires you need to connect are the pink(ignition), white(2nd ignition), yellow (start) and orange (heater). The orange wire is not an ignition wire, but rather your heater wire, it does not stay at 12v when your car is cranking. The brown wire is your acc wire that turns on with your radio. You do not need to connect this wire. Hope this helps in anyway.

How do I get the heater/AC to work then?

My car has:
Constant 12V-------Red & Red--Ignition harness
Ignition #1 12V(+)-Pink-------Ignition harness
Ignition #2--------Orange-----Ignition harness(heat/AC)
Ignition #3--------White------Ignition harness(Inst./Trans)
Accessory----------Brown------Ignition harness

I think bourigiridis meant to say something like this:

Hook alarm ign1 (often pink) to your ign wire (also pink).
Hook alarm ign2 (often pink/white) to your ign2 wire (white).
Hook alarm acc (often orange) to your Ign3 wire (orange).

The reason you can get away w/ this is because your heater doesn't need to be powered during crank. If that's the only thing on that circuit, I'd certainly agree...

Leave your car's accessory wire (brown) not hooked up, because you rarely need the radio (or anything else on the acc circuit) in a R/S, and if you do, you're probably in the car anyway and can just turn the ignition...

But if I hook the Orange to ACC. the R/S doesn't work. I have to use the brown for the R/S to work.

Ooppss!! I BAD.

This is the way I had it hooked up.

Car R/S

RED----------------------RED
RED----------------------RED
PINK-------------------IGNITION #1 Output
WHITE------------------IGNITION #2 Output
YELLOW-----------------STARTER Output
ORANGE-----------------ACCESSORY Output

R/S will start the car and run heater, but when I get in the car and take over with the key, heater goes OFF and rear window defroster comes on. I don't understand that.

When you say the heater goes off-- does it come back on when you turn it back on? If so, I would guess that you're just turning the key past the on/run/II position into the start/crank/III position from habit-- no big deal and easily fixed.

Did you hook up the remote start's rear window defroster wire? If you did, I think this is what's happening: it's getting turned on (correctly) by the remote start, but getting no power, because it's on the ignition 3 output. When you start the car w/ the key, that wire gets power.

These are just guesses-- I don't know that car,
