The "Two-Low" mod
101 - 107 of 107 Posts
The 2-lo mod on the non-pushbutton shifter version of your age of truck consists of undoing the blue plug on the passenger side of the gearbox, and substituting a switch for that connection. You can either add a switch in series with the wiring leading back to the t-case (allowing you to selectively override engaging the ADD), or in place of that wiring (giving over control of the ADD completely).

ok so what i get from this is that you are suppose to seperate the blue plastic piece and put a switch on either one of the two wires in there and then ground the switch? is that all? no fuse for the switch or any wires leading to the fuse box? does anyone have a picture of how the switch is suppose to hook up to the wires? sorry for being such a noobnot2XS said:
OK, here is my simplest suggestion:
1. Find the blue plug on the passenger side of the gearbox, there will be two wires running through it.
2. Leave the plug connected and cut one of the wires. One is the signal and the other is the ground-return wire for the signal - you can cut either one (but the white-black one might be better). Splice extension wires to the two cut ends and insulate around the splices. Make sure the resulting insulation is waterproof or it will get wet and corrode the connections.
3. Run the wires to where you want the switch, connect the switch between the two wires.
4. The switch should be normally kept closed. When the switch is closed, everything works just as it does now. Open the switch to disable the A.D.D. for the front drive.
5. If at some time 4WD stops working or becomes intermittent, one of your connections has gone bad.

i have my version of the 2 low mod on my taco, i do not have a switch on tranny lever, unfortunately i have the ADD front end : (, when i pulled my tranny and transfer out to replace clutch, i forgot to unplug the blue plug and when i did i snapped the wires, well when i put it back together i just wired up a simple switch and wired it up with those 2 wires going to ADD actuator (i extended them so i could put them where the TRD rear locker switch is), so now i have electronic lock out hubs, i can pull the transfer case back and have 2 low or lock in the hubs by hitting the switch. word of advice, dont lock in hubs while going over 5mph, she has a tendancy to grind a lil bit. besides that i love the little mod!
i'm interested and that actually seems like a very nice idea i will probably look at doing it too i need to keep my wiring intact for now while its my daily driver i'm not the wiring type i dont have much experience with it lol :saw: but eventually it'd be a good idea so can i get some details
