I have an aftermarket power door lock system installed.. it has one auxillary output.. I was wondering if I could wire it up so that the horn would honk when the lights flash when I lock/unlock the doors? I know I can't straight wire it because it would overload the module.. but other than that I am not sure.. please help?

is this a bsic keyless entry system without siren output?
if so, you can use the parking light output to power a relay to honk your horn too
86 - parkinglight output (assuming its neg)
85 - 12v
87 - ground
30 - horn wire (assuming its neg)

If you have an alarm system with siren output and want your horn to blow too
86 - siren output (assuming its pos)
85 - ground
87 - ground
30 - horn (assuming its neg)

it would have helped if you told us your alarm and the make model year of your car
dont need to know about your aux channel, that is used to control trunk pop, window module, etc.

It is made by Micro keyless entry systems. IT is the most basic of systems, just power locks, and it flashes the parking lights with the lock/unlock button. I drive a 2004 Dodge Dakota SXT.

HORN BLACK/ RED (-) @ CTM, 26 PIN PLUG PIN 5 the CTM (Central Timmer Module) is located in the DRIVERS KICK PANEL.

I dont know if the installer used positive or neg parking light. But relay setup goes like this
87 ground
30 horn wire
86 if neg parking light use 85 as 12v
86 if pos parking light use 85 as ground
