Thanks for the tip. I got one to keep in the trail tool box insuring none of mine ever actually fail

That's one hell of a find Tools and sherpa stuff like that should be in faqI got one from Rock Auto. Selected a 2000 Tacoma, 2.7L, Under the "Electrical-Switch & Relay" category selected "Back Up Lamp Switch". There are four brands available, I went with the BECK/ARNLEY Part # 2011788, $18.19.
Comes with the washer, bolt on, plug in, fit and works great. Just did 9 days of wheeling in SE Utah, worked every time.
I was going through and found this thread of what problem I am having, now the issue I am running into is that this part number is very similar to the switch on my 01 4runner, but the connector end is different. Any ideas what this switch number might be?

Jake, do you know where this is located on the rear diff? Do you have a pic or diagram?As you know the 84222-12010 fails pretty often on our trucks. Its located on the transfer case, as well as the lockers, and causes the indicator on the dash to blink even when they're working. I recently had the one on the rear locker fail on mine and wanted a cheaper alternative than 60 bucks, so her you go. NAPA Pt# NS6421. Its a neutral safety/reverse light switch found on many toyotas and is exactly the same as the 84222-12010. Retail price is 22.49
@Greenbean I used a stubby adjustable wrench for easier clearance. Looks like 27mm to me.View attachment 1839319
OK - I’ll bite.
I am envious of that Crecent wrench with the MM etch - what’s the source?
That would be dang handy, and you ***better remember*** where you got it, I’ve got a nephew who would love one in his stocking for Christmas above the 2 I buy to stuff in my toolboxes.![]()
Channel Lock has that, I pretty much ignore it, don't find it useful.![]()
