Power Trunk

This past week a power door lock kit with keyless entry and a trunk pop solenoid was purchased. Work on installing the trunk-pop solenoid began today. Tried just drilling a hole in the latch for the solenoid cable to lift, releasing the trunk catch. There was not enough leverage and the cable was binding on the inner metal sides of the latch housing. So... cutting and welding required. Added some length to the latch to give better leverage to the solenoid. Added a brace across the top and side to keep the latch from slopping off to the side of the trunk catch and to limit the latch's upward travel. The design of the latch is such that when the key is used, it will only lift the latch so far. But the latch will actually travel further if moved by hand or solenoid, and moving it too far will move it beyond the limits that the return spring can deal with. But not anymore! Then the next problem: with the lock cylinder back in place, it impeded the solenoid cable so the bracket for the solenoid had to be bent over to the left to clear the cylinder. Added some adhesive sheet rubber to the inside of the trunk lid to deaden the noise of the solenoid. With test power rigged up, it unlatches the trunk using the solenoid and still works with the key too, so it seems to be adjusted properly. I ran the power wire up the inside of the trunk lid but I had to knock off so I still need to run the wire into the cabin. With this hot weather, I am not working too hard on it so if I don't get power run to it right away, no big deal. The trunk is back to being operable with the key and the lid latches shut so the car is usable this way.
