I've kind of run myself into a jam here, and was hoping any of you great people could give me some hints/tips and check the wiring "diagram". Here's the grand scheme: I'm wanting to turn on/off my car stereo and "cabin lights". I want to be able to do so, both by remote and by a switch inside the cabin. As this is to tolerate a 23 amp current, the switch will control a 25 amp relay. To be able to remote control it, I'll be using a wireless RF relay. The problem is, the RF relay is only rated max 3 amps, so I need to have the wireless relay control the same 25 amp relay as the switch. I've made a simple schematic of the wiring. I am aware that, if the the cabin switch is "on", switching the RF relay on/off should have no effect. This is somewhat on purpose. Will this work - and should there be any complications?
