I have a problem with my AC cooling when I remote start. The motor blows but its not cool until I put the key in the on position. I think I have a 2nd accessory wire because my radio does not come on without the key. I was wondering if anyone had any ideas on what to do. I have a 1991 Buick Regal and the Viper 791.

check with the vehicle information on this site, looks like your car has a second ignition and a second accessory, if all else fails use a meter and check the wires behind the ac/ radio until you find out which wire is in the ignition harness.

Thanks for the info.

So with the Viper 791 there is a 2nd acc output but its negative. So the use of a relay is required right. Does anyone have a diagram on how to do this? So I'll know I'm doing this right.

at the end of the relay pack, theres a 3-4 wires harness and use one of those wire to power up the another relay.

click on second acc

Your Welcome. I will be updating some images on the site to have a better diagram for installer's so that there is no guess work.
