TOWD Tail Lights Isolation Network

Beginning to wire the grounds for the relays. When wiring--work in systems. What looks like complex at the beginning is actually simple this way. After the terminals are mounted to the wires Shrink tube is used to insulate the connections. Follow standardized color standards. It makes diagnoses easier. White - Ground, Green - Right Signal Yellow - Left Brown - Tail Lights. I put a blue stripe with felt pen on this wire for ground because the whites in the connectors are for reverse lights.  (I had to digress from the standard)
