How do I wire a Neg. switch SPST switch so it lights when on?

Alright I cant figure this one out, and I'm sorry if I don't use the proper terminology etc.

I have an accessory that is switched-ground. I want to use a switch that is illuminated. When the accessory is turned on I want it to light up. The problem I'm having now I think is obvious at this point negative switched= no power= no light.

Any help would be appreciated.

Just add a standard relay.
So from the switch run a wire to post 86 and from 85 and 87 goes to ground. 30 comes from the accessory.

So from the accessory part of the switch goes to 85. Then 86 and 87 go to ground. And 30 is the ground from your accessory. 87a is not used.
