The wiper motor from Finishline doesn't come with a gear as I remember. Their seperate gear is special, it offers about 100° sweep, distance of the drive pin from center determins sweep. When I was doing my car they offered a electrical plug body to go on the wiring harness that fits into the park switch on the wiper motor. Problem was you are on your own to come up with wire ends that fit the wiper switches pins and snap into the plug body. I was able to buy just the park switch for my wiper motor at Brooklands. The wire ends were available from Waytek,Inc. box of 100 #31073 , they are .187" for 14-16 gauge wire. The ternimal ends are listed as intended for relay. They also have the correct crimping pliers . They have loom ,wire etc. The lucas dash switch make two speed and auto park.
