I'm installing an asian wolf fm2009 in a gmc 2005 yukon and the problem is: this car needs 2 acc / 2 ign. wires, the alarm has only 2 options 1.- (2 acc / 1 ign). 2.-( 2 ign/ 1 acc). and also the alarm does not have a (-) output for extra ign-acc-str-relay. what should i do?

Thank you

You don't need to power up both the brown and orange accessory wires. You only need to power the orange wire to activate the climate controls. Use your built in relay to drive the white wire as it is a second ignition. You do need some sort of extra circuit like a negative out when running to trigger a interface for the Passlock II factory immobilizer. Check your install manual again as almost every system has this nowadays. If it doesn't, then it must be very old and I would shy away from it.

that is correct what sparkie said. the unit should have ground out when running, and u can use that to activate/triger ur passlock system.

The easiest way to add a 2nd relay would be to in fact add two extra relays.

If you tie both 85s of the new relays to ground and both 86s to current single ACC output you will be left with two high current, completely isolated circuits.

It doesn't sound like you need them, but that is how you would do it if you did.
