93 Buick Century Trunk Light

I know the '91 Riviera uses a switch right at the trunk pull down latch- so check there- or look in side the light lens- could be a mercury switch inside it....Brcidd - Engineer That Does Remote Starter Installs on the side.

Thanks, I'll just have to keep looking. Crazy Buick. I swear at the engineers constantly and pray for the day when I own a Toyota.

Its similar to a mercury switch. Is it a light socket screwed directly to the trunk lid? There is a metal ball inside the actual light socket that rolls when the trunk is opened. When it moves, it makes the electrical contact to turn on the light. To prove this, you can unscrew the light from the trunklid and connect a jumper wire to ground it. Then move it around and you will see that it will turn off when lying horizontal, but turn on when you tilt it. So basically, you cant tap in to use it as a trunk trigger. You have to install a mercury switch or a pinswitch.
