Look under vehicle wiring diagrams. If that is not enough specific information, try posting in audio.

I don't have a 91 manual but on a 90 and 93 they show two wires going to the switch mounted on the back of the door key cylinder.
Black/White is ground.
Light Green wire goes to the CCM.
When the key cylinder is turned in the direction to disarm the alarm, the Light Green wire is shorted to ground via the Black/White wire. This tells the CCM to turn off the alarm if it was set.
So your Bulldog alarm would splice into the Light Green wire. It would ground the Light Green wire to turn off the alarm. You should beable to splice into it at the kick panel.

The schematic shows the Left Hand power mirror has four wires going to it's motors. Yellow, White, White/Black (ground wire) Pink wires for heating element.
The Right Hand mirror does show a Light Green wire going to one of it's motors.
That Light Green wire that goes to the power mirror switch is for the Right Hand mirror control.
That is not the Light Green wire you want. You want the Light Green wire at the Key Cylinder.
It has to be in the bundle.

If you think you've got the wire, measure continuity to ground on it while turning the door key right and left. There's no need to remove the door panel.

The door lock system is called the 5 wire reversal rest at ground.
You cut a Light Blue wire and insert a spdt relay in its path.
You also cut a Black wire and insert a spdt relay iin its path.
You must have picked the wrong wires or wired it wrong since you're blowing the 15amp. power lock fuse..

I checked the wires at the kick panel w/ a test light and found the lock and unlock, the 12v constant to the door locks, the fasd wire, and of course the main 12v constant and good ground.
I even tried reversing the lock and unlock wires.
I don't know about spdt relays, could you explain the 5 wire reversal at ground please?

Bubba, you need to check your Helm manual to see if your car uses a pulsed 12V signal or a pulsed ground to activate the locks.
If you try to mix the two it can blow the fuses every time. Take what the alarm system gives you, then check the wiring diagrams to figure out what part of the circuit you can tie into. Worst case, you'll need an additional relay to change the signal.
