I have 2 ACC lines on my car that need powered during the remote start process.

One I assume is for engine controls and the other controls my radio, HVAC controls.

This alarm has output for just one ACC line. How do I wire up the 2nd?

You will need a 30/40 amp SPDT relay and wire up like this:

86 : GROUND OUT WHEN RUNNING
30 : to ACCESSORY 2 wire on vehicle
85 : to Accessory wire on Remote starter
87 : 12 Volts CONSTANT
87a: NOT USED

Thanks Jeff; 2 ?s though

what do you mean by ground out when running?

Where can I tap that 12v suppl from? Would it be safe to take it off the same line as the alarm 12v?
