underbody neon to dome light w/relay

It is simple to do. What kind of car will depend on how you wire the relay, so what kind of car?Certified Security Specialist

Alright, the wire in the car should be yellow/black and should be found above the passenger's kick panel. Take this wire and wire it like the diagram below. The - input is the domelight activation wire. The output goes to the neon's + wire. To add a toggle switch you will need to place a diode inline with the - input wire and tage the switch between the diode and relay to prevent the switch from turning on the domelight. As far as arm and disarm, arm probably won't happen. Disarm will turn the lights on if the alarm has the domelight supervision wired up.Certified Security Specialist

even though the dome is wired to light w/ arm and disarm it won't light?

Well, I don't know of any alarms that turn the domelights ON when you arm it. But when ever the domelight turns on the neon will turn on.Certified Security Specialist

do you think it might be better than to run it off of the parking lights then? also, is that relay a sdsp?

i mean a spst relay!

thinking a little more about what you said about the neons being on anytime the dome is turned on is not really what i am looking for. basicly, i want the neons to be able to turn on and off with a toggle switch and to also activate when i arm and disarm the system. that is the only time i want them to light. any other suggestions to achieve this? also, thanks for your help!

Parking lights is probably a bad idea. You can use the alarm's domelight supervision wire and have that control the relays instead of the actual domelight wire. It will come on only with the alarm and the switch. Relay type in this situation isn't a problem, you can use either a SPST or SPDT and it will work fine.Certified Security Specialist
