Hi guys
I have a compustar 920s that comes the cm-900 module
I have the basic wiring figured out. I just need help with the unlock/lock/ Parking lights/horn. I’ve spent 2 weeks trying to wrap my head around it and I think I’m just over complicating it.

Power Lock.........lt. blue (+).........@ either door boot \ Need relays to make (-) to (+) conversion
Power Unlock.......black/red (+)........@ either door boot / Use Door Lock Relay diagram in Relays section
The CM900 outputs (-) Door Lock/Unlock signals, your vehicle needs (+) signals.

Parking Lights.....brown (+)............@ headlight switch...................CN1-2 Green/White
Horn Trigger.......black (-)............@ steering column harness............CN3-7 White
Main ignition harness
The two Red wires are +12V constant.
The Starter wire is Yellow or Violet.
The Ignition wire is Pink.
The two Accessories are Orange and Brown. Use the CM900 Blue at CN1-5 for the Brown ACC wire and set CM900 internal jumper to ACC.

Soldering is fun!

That wire outputs a low power (-) Parking Light signal. Your vehicle needs a (+) signal to turn on the Parking Lights. The thick Green/White at CN1-2 is a (+) output rated at 10 amps.
