I have a 1986 DL wagon. I want to instal a 6 gang switch. The panel needs to be wired to the accessories fuse, the one that powers when the key is in. Which one is it?

 

Time to break out the test light. Turn the key to the position, accessory or on, that you’re wanting power and find the fuse that is powered when it’s in that position. I don’t suggest hooking it to any of the engine related systems.

That is one way. Thought a guru would know

I’d be pulling the power from the accessories wire that comes from the ignition switch, add an appropriate fuse between the factory wire and the gang switch setup. 

This way a factory fuse doesn’t have to do the load of what ever its task is plus what ever load you add to it. 

There are also a product where the fuse is replaced by a block that adds two fuses and a power wire - one fuse operates the factory wiring and the second fuse is for the added power wire. Easy to use but not the neatest looking when you pop open the fuse panel’s cover. If there’s one it’ll look better than having two or more in there I reckon. 

I hope this helps. 

Cheers

Test light did its job. Used the cigarette litter fuse for the panel. Thanks for the advice.
