I haven't done this mod yet... at a glance, it looks pretty straight forward. I won't get too much into the details... some of it I am not 100% sure of until I get some hands-on time with the mod.
Here are some hints that might help you to figure it out:
From left to right...
Pin One goes to a power source.
Pin Two goes to 86. For safety reasons, you probably want the switch to be inactive/disabled while your ignition is on (that way you or a passenger can't accidentally pop the rear while the VX is flying down the highway.) There's a way to do this and avoid a power drain... if I can just remember it. Basically, if you want it to work that way, you want the ciruit to have constant power until the ignition is swtiched on. It might take two relays to do this...
Pin Three goes to the pin switch... not the ground on the pin switch the other prong. When the door is ajar, the pin switch completes the circuit and turns on the indicator light in the switch to let you know the door is ajar.
Pin Four gets tapped to the Green with Red stripe wire coming out of the Defroster swtich harness.
Pin Five (below Pin Four) gets tapped to the Red with Green stripe wire coming out of the Defroster switch harness. This wire provides power for illumination. With this, when you turn on your lights, the switch will light up with the rest of the dash.
