Looking around at getting some pieces parts, it looks like I can make a "plug and play" setup. I can get the male connectors for the existing car plugs, and wire them into the relay sockets. Pop the relays on, mount it up where it needs to be and off we go! No cutting, no splicing. It'll just look different. Good thing is if either/both relays shiit the bed, pop them out and replace them Johnny on the Spot. Boom.
