Hatch wiring missing switch?

I believe in missing the top switch in this car that activates the motor but I'm not 100% sure on that.




I have 2 wires out of the relay and black and white one with no connectors on them that go to nothing. I have an orange wire out of the pigtail that connects to nothing. That black and orange wire is for the light and I believe I have it correctly connected to the white plug. The final wire is on the passenger side of the car it has the 2 wires from the front and a black ground wire coming off that is attached to nothing.

You're in luck. I just put the 88-91 striker-sensing switch in stock on my web site. Look for part number 207180 on top-downsolutions.com.

Thanks I will order one - what do I do with the leftover white and black wire out of the relay?

The white wire plugs into a black with Orange stripe wire on 90-91 pull-down unit. It is a switched ground to turn on/off the rear hatch light. Earlier model years had a manual switch for the optional hatch light. In other words, for those earlier years that white wire is unused.

Hey Lon I was able to get everything installed except the hatch relay. The connector under the dash doesn't match up to the relay I ordered unless I have the wrong connector. Also after installing the hatch release solenoid the key is much harder to turn - how can I remedy this?

That would be because you ordered the hatch release relay (706150) instead of the hatch pull-down relay (208180). Remove and reinstall the hatch release solenoid. It must match with the release tang that opens the latch.

Sorry should have clarified the hatch relay is good everything works with the motor I'm adding the hatch release button / relay and already installed the solenoid
