Single to Variable Wiper Speed Changeover

OK you would need the bottle/pump assembly - 65/66’s used a washer bottle and separate pump (you could also use a later bottle with the built in pump). Once the washer pump feed from the wiper switch is installed in an unused electrical cavity in the bulkhead, run another wire from the correspondent engine side bulkhead cavity to the pump. Install washer nozzles and the hose from the pump to the plastic Tee and from there to each nozzle. Any further questions, drop me a PM.
