Wiring

I have a couple questions on wiring. First is how to wire my universal wiper motor. It was just laying on the floor. There are three terminals on it a (-)and (+ )and and (S ). Can anyone help with this? I know (-) is probably ground and plus is hot but what is the(S)? I looked on line and nothing at all. Second while wiring the LED turn signals. I can only them to work if I touch a ground to the signal wire it's self. Does this mean I need to add a ground to the taillight housing? It is confusing because if I take the lense off there are three wires. A red and a black and a white. But, only two wires come out the back. They are black and green. I hooked the black wire to park and they work. I hooked the green to the signal wire and if I touch a ground wire to the hot signal wire they work fine????? If you can help I would really appreciate it! Thanks!!

I'd say (s) goes to the switch for the wipers......

On the tailghts the housing must be grounded the 3rd wire inside should go to the housing inside for ground......

Thanks! I will try putting a ground to the light housing. I figured just going through the body was enough ground. Thanks again!!
