i have mine wired like above and if i have it open, the light will still blink (no sound) w/ TRAC on. if closed, it acts like it would if unmodded. if i want to get into 4L TRAC on and i'm already in 4L, i have to get out into 4H, flip the switch, then put back in 4L.

I think it must be something to do with the relay in the circuit. It must allow enough current to ground the light without completing the full circuit shutting off trac?

^^ Try flipping the switch on and off while still in 4lo. If I kill the engine on mine while in 4lo it automatically resets to the blinking light. I just tap the switch again to set it solid.

If I could, one more question. What relay did you use? I think that might be why it works so well. Thanks again.

Radio Shack #275-0241 (alternate #275-241), SPDT (single pole double throw), 1 amp. Its a tiny relay that I mounted to a small piece of breadboard and wrapped it with a piece of soft foam to keep it from rattling and shorting out something, and then put it behind the switch. http://www.radioshack.com/product/in...ductId=2062481

Try to use 20AWG wire if you can find it...just makes it easier to work with and I believe the yellow wire is 20AWG or 22AWG.

^^ I dug out the diagram I made nearly 5 yrs. ago and honestly think there would be some confusion generated by posting it. Namely, at the time I did this I tied both the power for the relay and the light for the switch into that colored spaghetti mess of wires at the rheostat. I works but is the really hard way of doing it. Plus my diagram is pretty cryptic and specific to my '09. IDK it may be better and less confusing for one of you to get the switch and/or the relay and I can post instructions to walk you through it once you have it in hand.

Otherwise, if I get real motivated I would have to redraw the diagram but don't know if 2 different versions would have to be made: one for 2011 models and earlier, and one for 2012+.

33yrsoftoys, Chepo and others. Shazaaaaam! Found an error in the parts manuals today. Looks like the only OEM A-Trac switch for Tacos may be 84988-04060 with an amber back light and it is intended to go next to the cigarette lighter. This is the one I got for my '09. Note that Post No. 592 above has now been edited to reflect this.

Just curious, what are your experiences with the YWM in snow? I did the YWM yesterday and took it out to try in the snow. Four different times I tried starting in VERY limited traction situations and it did NOT get me out. Two times in 8-10" all 4 just dug myself deeper, then had to shovel my way out. Then twice on hard snow packed/icy hills. I would stop in the middle of the hill try to start from a stop. I would either just sit and spin or wheels would spin while I would slide backwards.

I am pretty sure that I did the YWM correctly. When I was stuck in deep snow, the 4Lo light would blink, and I would watch the left rear tire spin, then stop and I could hear the right rear spin and it would go back and forth.

Now, I am assuming my BFG AT's with 4/32's tread left didn't help the situation. I am long overdue for new tires. But that is a subject for another thread. :-)

So, two questions:
1. What are your experiences in snow, either deep or hard packed?
2. I am assuming I did it correct (I have limited mechanical experience)? Since in 4lo I saw the tire spin alternating from side to side. In the past, while I was in 4lo the tires would just spin.

Just for the record. Disconnected battery. Pulled out first white clip of wires. I cut the second yellow wire (with the thin black line), and installed a switch that I attached to the inside of the glove box. My truck is 5+ years old and paid off so I am not worried about dealer and warranty. When I switch it off, the 4lo goes solid and tire just spins.
