    Hi all

    I'm trying to add another power supply into my already made series ring. I built my circuit with entry points to do this but I can't for the life of me remember what I need to put in to stop a back feed. I wish to add my new fog light switch and dimmer switch to this circuit howler ever if I feed power into the circuit from the cigarette lighter It will carry on sending charge to the door relays which in turn could blow a fuse

    Here's my diagram and the dashed lines is where I would like to put my new switch, do I need a relay switch? What I'm looking for is an ability to make an OR gate

    Use diodes in the "+" wires of the various switches. This will create a virtual "or" circuit. Hope you read this before your post gets moderated.
