Wiring help

What I would do is use that switched line you have to activate a 30 amp relay. That would give you an additional 30 amp circut of switched power. From the relay you could make an aux fuse box or just a barrier strip terminal to tap the power from. As far as you guages go, tap into the factory guage light circut so it will dim with the dash guages. If you need a wiring diagram for a 69 Cuda, I can email one to you :thumrigh:
