I’ve had an intermittent issue with my 4WD dash indicator light, and when it finally went out I traced it back to the switch screwed into the side of the transfer case. This is the switch that when engaged, closes a circuit that lights up the dash.
It’s a little confusing what part this actually is: here is what I found:
Perhaps someone who has replaced one of these can help narrow down to the correct part number for anyone who wants a direct fit replacement?
Even the dealership couldn’t figure out which one I needed and price felt a bit high, so on a hunch, I took a different route. It seemed that Toyota wouldn’t vary their switch design that much, so I bought 3 different similar aftermarket switches for the same period Toyota vehicles. One of them was a T100, can’t recall the others. These are NOT official part interchanges, just my guesses:
Beck Arnley 201-1788
Dorman 600-544
Standard Motor Products LS240
Turns out, all of these work. Thread pitch and diameter are the same. I installed and tested each with a DMM to ensure that the switch was being engaged, and all are within a millimeter of the original’s length. Of the 3, the LS240 is the only one with a pigtail and it happens to be dead-on dimensionally. You will need to clip and swap the connector end with your original, but that’s about 10 min with some butt connectors or a soldering gun and some shrink tube.
Total cost: $20-40, depending on switch.
