If you wanted to retain the KARR system, check into the wiring of the 4040a for an auxiliary output. Aux outputs are usually triggered by a combination of buttons on the key fob. Say like pressing lock and unlock at the same time, then the brain provides a neg pulse on a wire in the harness. (just a for instance). Then use this wire to tell the RS to start the engine.
Some of these RS stand alones can use a double pulse. In which case, you would tap the unlock button twice to activate the remote start. I think this is kind of cheap compared to using a RS/Alarm Combo or using an Auxiliary output from another alarm.

I may be in luck with the AUX OUT. I found some wiring info (below).IN BOLD (12 & 14)
From past experience when I first started using the KARR 4040a system just finding a users manual proved to be very difficult. I'm surprised I found the wiring info as quick as I did tonight.
But I think I may consider looking deeper into a complete newer Alarm and RS package from Computar and DEI if someone or rep of these companies can offer me any reasonable situation that would out perform what I have now.
Karr 4040A wiring
1. Red = 12V Constant alarm power
2. White = Parking lights output
3. Red\White Stirpe = Parking light selector. Cut this wire and connect it to a ground if using a (-) parking light, keep it connected for a (+) parking light
4. White\Black Stripe = Siren Output (+)
5. Purple = (+) Door Trigger
6. Yellow = Ignition
7. Green/White = Domelight
8. Black\White Stripe = Horn output (-)
9. Black = Ground
10.Orange = Ground when armed
11. Brown = Door Trigger (-)
12. Light Green = Accessory input (-) trigger
13. Dark Green = (-) trunk trigger
14. Dark Green\Black Stripe = Accessory (-) output trigger - Must use relays.
There is also a four wire lead ( red,green,red,blue ) that plugs into the side of the unit that I have no idea what it is for?
Red = (-) lock motor
Green = (-) unlock motor
Red/Black = 2nd unlock
Blue = Trunk shunt
2pin:
red = (-) power lock
green = (-) power unlock
