Aftermarket courtesy lights

Guys I have a 72 Chevelle 99 complete from a body off.

I bought an aftermarket dual courtesie lights to mount under the dash that come on when doors open.

Any ways this kit from NPD requires that I unplug one of the two wires connected to the left door light sensor (push pin).

Is anyone familiar with these pre wired kits because I tried to follow the instructions and got reverse working order. If I push the pin in the damn light comes on.....


I'm lost need help.

Re: Aftermarket courtesy lights

You should have two wires coming out of each of your new light sockets. One wire will go to a constant 12 volt source and the other goes to the pin switch.

When the door is closed, the wire going to the pin switch is not grounded and then the lights will be off. When the door is opened, the wire from the light becomes grounded and it lights up.

On some GM cars, on the left driver's door switch there are two wires going to it. One is for the factory dome light and the other is for the key buzzer circuit. If your driver's side has two wires and you don't know which is which, pull the switch out and ground one or the other until the dome light comes on. That is the wire and terminal you need for the added lights.

To get power for the added dome lights , you can use the one 1/4" male terminal in the center of the fuse block labeled BAT and this terminal is also fused by a neighboring fuse in the fuse block so if a short does occur, the fuse will blow.

GM normally used an orange wire as the constant 12 volt for powering the dome light and then a white wire was the ground to activate it.

Re: Aftermarket courtesy lights

As already mentioned you need to tap into an orange wire (12 volt constant hot) and a white wire (ground) to get those lights to work. You can find them behind the dash.as they are used for dome light/ glove box light/console courtesy light and the radio may even have a constant 12 volt hot in that bundle. Easiest place to hook into the white ground would be the door switch.

Re: Aftermarket courtesy lights

If your using the original style GM add on harness it's a simple plug and play You only need to plug in 3 wires. Very simple.
