97 mitsubishi galant remote start

First off this is my first RS and the car is a 97 mitsubishi galant (no power locks, no power windows, no alarm) 5 speed. The unit is a prostart ct-3360 (I read the reviews after I bought it). I printed out the

The part that I'm having trouble with is the "External Trigger input" it says that this input will start the engine when it receives a 1 second ground pulse. Since I dont have power locks I read on this site that I could tap into the parking brake input for this. Is this true?

And I could use some help with the clutch bypass "(-) Ground out when running" wire it says that this output gives constat 500 mA ground when the system is running. Having some trouble locating the relay.  Although I found 2 wires black / blue on the side of the clutch pedal. Is that black wire the one I am supposed to use?

And last question there is a small yellow wire and the install guide calls it a "(-) Parking light output" - Negative 500mA parking light output. I dont know where it is.

I've got a ton of help with a print out of this link but it dosnt cover everything for a RS https://www.the12volt.com/installbay/detail.asp?info=alarm&year=1997&make=Mitsubishi&model=Galant&ID=18470&type=Alarm

Thanks

I am aware of the dangers of a RS, thanks for the reminder. I do however have several hours and some money invested in this project so if anyone could help me it would be very much appreciated.

thanks
