That looks about right. I have the tach control and it's pig tail. It's the harness from that connector up to the tach and down to the bulkhead connector that I'm looking for. Also the wire that goes from the bulkhead connector to the coil. It's gray wire with a black tracer. I just figured that there was a restoration company with reproduced ones since they seem to have all the other harnesses for that car. The connector is a 4 wire type, but, only 3 wires are used.
