I'm trying to hook up the wires to my wiper motor and pump on a 66 ss. It is a two speed motor. I have installed a new harness but the old one was butchard so I have no reference. The schematic I have showes only five terminations and I have six. I have a light blue, dark blue, and black wire coming from the wiper switch. I have a light blue and yellow wires coming from the harness. I have yellow wires that some how fit in between. I'm not sure if I'm missing wires or what. Any help would be great!

Thanks

The dash/engine harness has the wiring for the single speed motor, yellow and lt-blue. When installing the optional two speed wipers a separate harness is used. The two speed harness should have a connector, with only a yellow wire, that mates with the single speed wires/connector, the yellow wire is power (fused IGN) the ltblue wire is not used, has no connecting wire.

The two speed harness has the 5 wires, the motor gets the yellow black and lt-blue wires, the washer pump gets yellow and dk-blue.
