Re: Alarm Wiring - Light Flash Output
"In the (+) position, the on-board relay is enabled and the unit will output (+)12V on the H1/2 WHITE wire."
If I read that correctly the alarm unit has an internal relay to drive the parking lamps when you select the + jumper position.
Tie this White wire to the parking lamps power wire.
Don't use Scotchloks or butt splices. They mangle vehicle wiring harness.
