Thanks for your comments Danny. I'm not having any battery drain problems (yet) but I do have a problem with lamp warning light always being on even though all the bulbs have been checked. I'll have to investigate further. If you get a chance I'd appreciate more details on where the "24 screws on it interconnecting 12 wires" are located. Is it in the tailgate or in the body?

I don't think the switch in the door is the problem since I just trigger the alarm system and according the the wiring diagram it uses the same switch.

Looks like the pump is actually under the "floor" under the right rear seat bottom in the wagons. Shouldn't be too hard to get to since the seat bottoms are easily removed. And since it require removing the carpeting I might be able to get at that power distribution point under the floor.

Any more comments welcome. I'll let you all know where this leads.
