On our Ultra Super C, Gulfstream used a 30A headlight relay to control the slide interlock. Look around your fuses and hi-amp breakers for a small black box with several wires going to it. Take a peek at the e-brake wiring and see the color of the wire gulfstream used to tap the e-brake system, you should find that same color at the relay. On ours it's yellow.
With a volt tester at the relay you should find 12V hot on 2 legs if you have your parking brake set. The 3rd leg should have 12V as well, if not, the relay has failed.
You can go to any automotive store and get a generic 40 or 50A automotive headlight relay. Just make sure you put the wires back to the same numbered terminals as they came off. If the relay is exposed to the weather check for corrosion and buff the connectors up if there is.
