I have a 1985 Pontiac Fiero, it is the easiest vehicle in the world to wire into because it is basic GM super-simple wiring.
Anyway, I'd like to install the new Compustar Pro P2WSSR with full alarm system and remote start.
My question is, is there a negative or positive input on that remote start to wire a push button switch to to turn it on and start the vehicle, or would you simply have to solder onto an extra remote and hide it in the installation?
Thanks for your help!

So I think there is a negative input on an AstroStart that will perform the startup feature, and then I could use a pulse after start negative pulse to engage a set of latching relays to keep the vehicle running as long as I want it to after the AstroStart timer has shut down.
Does Compustar have a similar feature? Negative input startup?

I'm not sure of the wire colour, but is the temp sensor wire.  Negative trigger if I remember correctly.
Think. It's not illegal yet.

Ok, I've pretty much figured out how to do this:
1. Use a push to start button to activate the negative trigger input on the remote start to turn on the starter. That way the remote start initiates the startup sequence correctly.
2. Use a "pulse after startup" wire to turn on 4 latching relays to control the ignition wires AFTER the remote system startup.
3. When the brake is applied, the remote start turns off, but the latching relays still keep the car running.
4. When the "push to start" button is pushed a second time, it disengages the latched relays and the car shuts down.
The only thing that I haven't quite figured out yet is how to make it actually secure. At this point anyone could walk up to it and hit the button and start it and drive away. Even if it is armed and locked, because if they break in and hit the button, the remote start tells the security sytem that it is OK to operate.
Maybe I could use a seperate security system all together as a piggyback system ONLY to offer security to the push to start button system.
OR
I could incorporate some type of RFID tag system... Hmmm, this could get tricky.

I think Crimestopper has an "infinity run" mode............ that is, you can choose your typical runtime of say, 10, 15, or 20 minutes, but then there's another option that just keeps the remote starter turned on forever.
You could install a Crimestopper, and then put a toggle switch to interrupt the remote starter's brake input.......as long as it doesn't see power on the brake wire, it'll keep going forever.
Only two downsides to this setup:
1. While driving, you're relying on the quality of the remote starter, and the quality of your installation work......if either should fail, the car will shut down, not a good thing if you're on the highway.
2. As long as the remote starter is on, the parking lights will be on too. You install a second toggle switch to disable the parking light output of the alarm......or buy a double-pole, single throw switch........you could flip the same switch to kill the brake wire, and kill the parking lights at the same time.
What is it you're trying to do? Make the car so you can drive it without keys? You're still going to have to do something about the steering wheel and gearshift locks.
P.S. Whatever you do, I would also keep the original key-based ignition system in place, so you can still drive if your setup fails.

Looks like I can get a genuine OEM S2000 start button on Ebay for $40

I'm going to try it on my Civic soon to figure out the best way to do this.

1. I'm a little concerned about the first part of your reply... I agree with you. I'm hoping though that by using good quality components, it should hold up OK. I'll have to see how hot the relays get by using them for long periods of time...
2. I'm going to be using latching relays to keep the ignition system energized after I hit the brake to shut off the remote start system. Also, these latching relays will be able to be turned off with the push of the start button again some how...
3. I'm going to disable the steering wheel lock.
4. I guess you're right about keeping the ignition cylinder in tact just in case... But this will be so cool if I could get rid of it! But, you're probably right... we'll see how it goes.

There should be a pink wire on the secondary harness which is a negative trigger start wire.

I installed the entire works into my '92 civic tonight just for trying it all out and stuff, but I have 2 issues with it so far:
1. Steering Wheel Lock - I don't know how to remove it
2. Needs 2 buttons - One for start, and one for stop. - I need to figure out how to do one button that can turn it on AND off...

1. i've never seen anyone successfully remove the steering wheel lock... keep us updated on that one...

2. use a latching relay circuit -- one input latches it, a second input unlatches it .. the diagram is on this great site
