hello
ive got a '79 TA
i know this is a 3rd gen forum, but i tought maybe someone here has done something similiar already.
i want the key warning buzzer to buzz when i have the lights still switched on and i open the door.
anyone got an idea?

thanks

 

Get a seperate buzzer, wire power to it through a door pin switch (add one or get one with 2 sets of contacts, one normally open the other normally closed) from the head light switch "on" position then run the power on down to your buzzer.

Headlights on, door opens, buzzer sounds. Simple.
