I am trying to install a remote hatch switch that goes with my car alarm into my '92 Camaro and I am having problems. I tapped the hatch wire at the switch(brown wire) but it isnt working. The wire from the alarm is a 200mA (-) wire that is supposed to drive a relay only... I assume that the switch in the console runs to a relay for the hatch? Any ideas on what I may have hooked up wrong?

Thanks.

The brown wire at the hatch release switch can have +12V present on it under certain conditions. If the low current pulsed ground trunk pop output of the keyless entry unit is engaged when +12V is present, you will permanately damage the controller. To avoid this complication, use a seperate external relay to send a +12V pulse to the black wire at the hatch release relay under the center console.

More info is avaliable here:

I wired it up without the relay...do you know what circumstances cause the wire to get 12V? Thanks for all the help on the other posts, and that alarm info webpage makes it so much easier to do.
