Hi, I already have a motorized pull down assembly in my 86 trans am and I dont have the switch. The feature didnt come with my car I guess. I know I need a relay, solenoid, and wiring. So does the solenoid just hook up to my motor assembly? I dont understand how it works. Please help. And I need to know where I can get a solenoid from. Any one have pics so I know what it looks like?
