Get well soon, Scott.
BTW, I don't think you have to have a relay. The VW I owned had a hatch release switch that worked all the time... with or without the ignition being on. Just have to make sure you have a fuse in there somewhere. Took the time to draw up some diagrams for three different ways of wiring up the switch and solenoid. Remembered how to make it work only with the ignition off and not cause a battery drain too (a 5 post relay!)
Amack: You can not use an existing relay in the VX. No way. The relay is an additional part you have to source on your own if it didn't come with Tone's rear gate popper kit. You'll need to buy some small female spade connectors to be able to hook wires up to the prongs. Take the switch with you to the auto parts store and find the right size. You'll need to buy some heat shrink as well to cover up the connectors so they don't touch eachother and cause a short. Also, don't go crazy with the wire... heavier gauge wire will be hard to work with and take up space. Use a smaller and more flexible gauge. Look at the existing wiring on the stock defrost switch harness and try to match the wire gauge. Use masking tape flags on the wires as you go so you can write on them (so you don't get the wires mixed up). Other than that... can't get any easier.
**Edit** Since the diagram didn't help anyone... I have removed it.
