Beautiful! The rear hatch solenoids rarely work correctly. They get positive 12V from a brass pin pretty reliably, but they do not get a good ground. They ground to the hatch which in turn does not ground to the body. A larger grey stud is supposed to provide the ground to the hatch.
I highly suggest the same two modifications I do to all of mine:
1) Put a ground wire from the body to the rear hatch adjacent to the rear defogger if you have one. There is a notch in the trim for the rear defogger wire to ground to the body, I use that notch and ground screw to add my hatch ground.
I actually measured across the solenoid before and after adding that ground wire. The voltmeter reported 12V after this addition and only 4 volts before it, which explains the lazy solenoid action
2) I put a 3M rocker switch available at Walmart into the supplied plastic bezel backwards, then use the existing holes to mount it where the button used to be in the glove box. This sends steady 12V to the solenoid, which would burn it out. It doesn't burn it out because I interrupted the wire and put a doorbell switch above the passenger side taillight. I can now open the hatch from the rear of the car and I only hit the glove box switch to lock the hatch, not to open it.
