ABS disable help

I want to install an ABS disable switch. I don't want the failsafe function, just a plain on and off toggle type switch. Only thing is, I am a little confused. In my owners manual it shows several different fuses that have something to do with the ABS. Fuse #20 in the passenger fuse panel is for the ABS MODULE, back up lamps, flashers, etc. It also shows Fuse #15 in the power distribution box to control the ABS (SOLENOIDS)... #17 is ABS (MOTOR)... I'm not sure where to tap from, if the 04+ is different, etc. Hopefully Rwenzig or Griggs can help me out? Thanks in advance.

i did mine with the reset button and stuff... but im an 03.

i would recommend pulling fuse 20 from the passanger fuse box, then see if the abs light comes on. if it does then you will need to tap into that wire.

if you want it real simple you could just pull the fuse when you dont want it and put it back in when you want abs agian.

Unlike the 2003 model, the 2004+ has several other items powered from the same fuse that supplies keyed power to the ABS. Removing the fuse would disable the ABS and those other components as well.

I am not recommending that you disable your ABS - that decision is up to you. The wire that enables the ABS when the ignition is on is the solid red one at the ABS control module.

OK. I went out and tinkered with it. When I pull #20 in the pass. panel, it kills the reverse lights etc. It also leaves the park brake light on, when the brake is off. #15 in the dist. box disables the abs, but still leaves the park brake light on. #17 works well, it only displays the ABS light and doesn't take away any other functions.

So basically, if I trace the solid red wire to the ABS module and put a switch in that line, it will do what I want, correct?

There are two red wires to the ABS module, a larger 14ga from fuse 15 (underhood box) and the smaller 20ga from fuse 20 (SJB). Interrupting the 20ga red wire to the ABS module would keep it from operating.

So, I will have to sacrifice my reverse lights, etc in order to do this? There is no way to do it from #17? Thanks for the help...

Off-Roading, ABS doesn't work too well in sand, gravel, etc..

Switching the 20 gauge red wire is the way the factory does it. When the ignition switch is turned off, it interrupts power to the 20 gauge red wire, signaling the ABS module to turn off.

If the #20 fuse is pulled from the SJB, it kills several components on several wires. If the 20 gauge red wire is cut at the ABS module, it would kill the ABS only, not the other components.

Depowering the yellow/light green from #17 would disable at least part of the ABS, too. Since there are other power wires in, the overall effect of doing this is unknown. AND, it is important to remember that it is a major 40 amp power circuit (!) and would probably require the use of a relay to switch it.

Ahh, thanks, I got it. I'm usually pretty good at figuring out electrical stuff but this kind of threw me off. Thanks again...
