Default Headlight harness for 1963 GMC truck

Hope all are well. I am needing to replace the headlight harness wiring for 1963 GMC truck. I bought the headlight harness that LMC has for that year of truck and they say works for both GMC and Chevy. But the harness from LMC has the red wire going to starter by itself and a single black wire by itself and then a double connection with two wires on it. On the 1963 GMC the light harness that is on truck has a three wire connection going to starter that connects with another 3 wire harness near the air filter that then goes to the starter. Does anyone know where to buy a light harness that will fit the 1963 GMC truck with the 3-wire connection set up? Or has anyone retro fitted the LMC light harness so they it connects into the existing 3wire connection that goes down to starter? Here is a picture of the LMC type headlight harness with connection highlighted in yellow that talking about above. Thanks.
