I thought that solenoid kit from PATC was the same between A500 and A518? (42-44-46 RH)
One would think so, however maybe because they built the kit for trucks with the A518, they dont have any experience with the smaller A500 and dont want to sell it and possibly end up with returns if it doesnt work. I'd be willing to give it a shot, or just mount 2 manual operated switches like Mike str12-340. And be done with it. Seems to be easy enough.

Single fused hot lead to center pin on the transmission plug. One wire to lock up solenoid pin, to switch, to ground, one wire to O/D solenoid pin, to switch, to ground. Turn them off for around town, turn them on above 55mph for freeway cruising. I really like the switches Mike picked. I wonder if they are back lit for night time driving. I'd probably mount them inside the ashtray in the console, so at car shows, you just slide the ashtray door shut and they are hidden.
