Installing an alarm on a 68 Chevy

[goodsauza]

I am trying to connect the wire from the unit to the brake lights. I already try from the white wire that is in the top of the brake pedal. Also on the white wire stering colum hardness. I try + and - and it does not work. Is there another place where I should hook up the wire from the alarm so the brake lights will blink when I turn off and on the alarm. Any help will be appreciated.

Thank you.

how many volts is your wire putting out?

If its not 12volts its not going to light anything up.

by the way your brake switch is always hot,pressing the pedal allows current to complete a loop turning on brake lights.

the easiest would be hooking up to the dark green wire that sends power to the horn,its self grounding and the momentery voltage sent out from your alarm will sound your horn.
Or you could pull your light switch and splice into the brown wire that runs your parking lights.(do not use the red wire in your light switch)


the dark green wire in headlight switch is for power TOO headlights/

horn
(drk green)comes out behind fuse box and runs to a relay on inside the cab firewall
