2007 f150, viper 5901

(1) Could you tell me how would I do the wiring to turn on the factory wired heated mirrors on with the viper 5901?

I know that the wire harness for the viper 5901 has a H2/16 (-) 200ma 2nd status/rear defogger output.

Do I need connect the H2/16 wire to the back of the factory switch for the heated mirrors (pin 10 circuit 1010 (DB-OG)) or do I need to wire in another relay?

(2) I would like also to know how you do the second unlock on the viper 5901 or how it works. My son wants it to unlock the drivers door the first press unlock and unlock the rest of the door on the second unlock like the factory.

(3) How would you wire more than one sensor in? The Viper 5901 cpu1 has only one Optional Mux Port (for additional sensors). What I want to do is connect a Dei 508d and a 507m to the alarm. I was told to cut the plug off one of the sensors and wire the together as one. Does just doesn’t sound right to me but it maybe my only way.

Any help on the on these problems would be very much appreciated.
