I have been toying with the idea of installing an on/off switch for my under hood lights, so when I have the hood open for an extended period of time I don't have to worry about the battery drain, and prefer not to keep pulling the connectors apart. But there doesn't seem to be a simple, single point to interrupt the circuit - but logically there is one. Anybody got an idea on the best solution?

 

Pull the 10 amp fuse in the fuse holder near the drivers side front wheel well. It will turn off both underhood lights.

 

OR go to lowels or home depot and buy a lamp roll switch, those cheap plastic ones that screw together and put them in-line on the wires, then roll on or roll off - no need to pull fuses

 

Or you can unplug the weather-tight plug for each light.

 

Read the post, he doesn't want to keep pulling the connector each time.
I just leave mine unplugged 24/7/365

 

When I took the C4 103 Class at Gordon Killebrew's place in Tenn. we talked about this very issue. I wanted to make a set of switches that plugged into the factory harness with factory connectors and was easily removable. Since we had some free time, Gordon and I sat down and made two switches to do this.

Gordon has a boatload of extra parts and connectors at his place, so we stripped 2 weatherpack connector sets from a junk wiring harness to use in between the original light connectors. We got two male and two female connectors that match those used on the Vette for the underhood lights. We soldered a toggle switch in between the additional connectors and covered it with heat shrink and waterproof electrical tape. Then the male connector that is soldered to the switch is connected to the female on the car and the female soldered to the switch is connected to the male on the car. It works great. I can flip on either or both lights, one at a time. If I wanted to go back to completely stock, I just unplug the connectors and reconnect with the switch out of the loop.

You can get the connectors at any junk yard that has GM vehicles. The connectors can also be bought new from Delphi or any auto supply place that carrys the Weatherpack line. You need 2 males, 2 females, a switch, some crimp connetors or a soldering gun, heatshrink, and a small can of liquid elelectrical tape (Home Depot).

You can also order them from Gordon directly. He is making and selling them now. His price of $10.00 is a steal.
