Plug and play - Headlight Relay Kits
Just curious, Rob. We used 8X4 sheets of plywood with nails and screws to make form boards. We had a list of the color, gauge, and type of wire to use. All break outs were marked, and the pins and connectors were called out on the BOM (bill of materials). We use crimps instead of soldering, because it's quicker, and solder tends to crack under vibration. I can see you doing this in your shop. Paul.
