A separate/improved switch design is always a possibility - but without actually taking the door apart to get a first-hand look at the design (as well as available space!) - its hard to see if an improvement could be made to the current design. If I do go thru the hassle to take the door apart and evaluate the latch design, I would most likely replace the switch with the factory switch and take relevant dimensions of everything while its apart. And then I'd work on a new design and have it in place in case the switch fails again. Finding off-the-shelf switches, that are sealed (due to the environment it's exposed to), that has similar mounting hole patterns, with action arm that is shaped correctly and articulates in the free space thats available to it inside the door is not something one just goes to NAPA and they're on the shelf! And I certainly wouldn't want my door in pieces for those weeks while the research was being done! Luckily, I'm a pretty good machinist and have a nice machine shop at work - so creating a custom mounting plate or articulation arm wouldn't be a problem - but again, having the access to the entire design is key. Unless I just order the replacement switch/latch mechanism from my dealer and see exactly what it looks like and what I have to work with - instead of taking apart the door?!? Hmmmmmm.......
But sorry, no pics. Its just your basic "cut a wire and solder a loose wire onto it and connect the other end of the loose wire to ground". The cutting/soldering was done below the steering column at the fuse panel and I had to pull up the plastic bezel that went over the driver door threshold to expose the ground bolt I connected to. No tools/tricks needed to remove the bezel.......just pull straight up and walk off the bezel piece as it curls up the door edge by the door hinge. You just push it back into place when you're done.
All I needed was a pair of wire cutters, wire strippers, soldering iron/flux/solder, electrical tape, ring terminal and a socket wrench to remove the ground bolt going into the chassis. Oh - and a scrap piece of wire! And I won't even mention a headlamp - what sort of car work can be done in this day and age without your trusty headlamp!?!? :-)
