94 GT Wiring Help Needed

I was having problems w/ only one of my door locks opening w/ the key fob, none would lock and interior door lock switches did nothing at all. I found an old alarm system on the car and I don't have the remote for it. It did control door lock functions etc... at one point w/ the units specific remote. I contacted the alarm manufacturer who informed me it's an old model no longer made so no replacement remote avail. Needless to say I purchased a new system from the same company in hopes it might solve my door lock issue, now I'm like 75% done w/ the install but need to find a few more wires to make this work or at least a schematic of some of the factory wiring. Maybe a pinout of the headlight switch?

I need to find the following wires to connect to: (I kinda think I know)

Horn output (yellow -) to the right of the steering column
Parking Lights (brown +) below driver side kick panel
Trunk Release (purple/yellow +) below driver side kick panel. (I cannot find the wire looked at some schematics and they all tell me purple/yellow yet not seeing it.

The instructions are very general as you can imagine. Also it is giving me 3 schematics for door locking systems and I'm not sure which I have

negative trigger system, positive trigger system, or 5 wire reversal (rest at ground)?

I'm thinking it's a 5 wire reversal?

may have answered my own question but does that sound right?
