Hi everybody,

I'd like to contribute by making a remote start alarm pictorial for a vehicle that returns different wiring diagrams on the internet. The vehicle a 1996 Chevy Astro van has power locks windows and other extended features. I'm providing start pictures with name references for any assistance that can be provided.

Driver kick panel!?:

Center module:

Wiper/brights switch

Headlight switch:

Ignition harness:

OBD:

I'm going to start by soldering:

[RED 12VOLT 30AMP ALARM INPUT] to the [SOLID RED IGNITION HARNESS]

[SOLID BLACK SYSTEM GROUND INPUT] to [VEHICLE CHASSIS]

now I must figure out which reference to use for the door trigger either it is [PURPLE (-) HEADLIGHT SWITCH] and/or [BLACK/ORANGE DRIVER KICK PANEL]

and which+what reference for the horn wire either [Horn Dark Green (-) Driver's Kick at Relay or at Pedal] or [HORN BLACK (-) @ STEERING COLUMN HARNESS]

Anyone familiar with it?
