ABS disable mod for 05+ Tacomas w/o VSC & locking diff write up *pics*

tHANKS bRYAN AND tRAVIS. jUST DID FINAL WIRING WITH OIL CHANGE AND TOOK 30 MINUTES.
Wired up switch and placed it on the blank yesterday, took 15 minutes.

Some tips if you do it:

Do it like Bryan and wire close to the grmmet(drivers side) Blue wire with silver bands that go around circumference(check back at the harness to check if correct wire like Travis' write up and pics). You have less primary to zip tie and closer to switch.

I try to push through the grommet with the brake cable line and use some extra thin and long needle nose pliers to push it through beginning on engine bay side, then look under the drivers side with flashlight and just grab it with same long nose pliers and pull it through. Use Bright colored primary (I use red) to distinguish it from other wires (most are black in the area).

I missed last Colorado MOD and trail run weekend, but now ready for the next with the new ABS disable MOD..

 

I'll have to throw some pictures up when I get some time. Did the mod though and everything was a success. Obviously the install is a breeze and very straight forward. Works as intended and now I can stop thing beast with confidence off road.

FWIW I spliced in at the firewall in order to run less primary to the switch. Didn't feel a need to running wire all the way over from the controller back inside to the switch.

 

Just did this tonight. I couldn't wait so I started at about 1am. finished two hrs laters bc of that dang rubber mount on the firewall. thanks again man!!!! will def. help out alot!

 

To clarify, this kills the ABS, and thus all of the traction/VSC stuff for the ones that have it? I have a 2010 with VSC/ALSD and when I flip the ABS I actually DO want all of the traction/vsc crap gone as well, 100%, none of this having to be in park and holding buttons for 5 seconds, then only being able to do it under 30mph, etc etc etc.

Also curious if it will cause any other electrical issues, either immediately or further down the road. I don't want to fry any black boxes by disabling systems that need to be on, but I suppose it's the same concept as pulling the fuse from the fuse box (as people have already said), and with a blown fuse nothing would really fry - but then again, most people who see the ABS light on are immediately going to have the issue fixed instead of be pleased.

So, if anyone with a 2010 has done this and has anything to input please let me know ^_^

 

so if we have VSC, we follow the same instructions, we just lose all traction control (similar to holding button for 5 seconds?)

 

A similar method to pulling the fuse would be to wire a switch to the contacts of the ABS fuse holder via spade connectors. I'm not sure if the light would come on or what other systems would be disabled, someone who pulls the fuse could answer that.

Used in snow 1 st time today on snow packed streets. Awsome being able to stop. Must have cut breaking distance in half.

 

this is listed for only tacomas w/o diff locker, is there any way to get it to work with a 2WD TRD with a diff locker?

 

I'm also interested in anyone that's done it on their 09+ I suspect it would also disable TRAC? which would be a negative for off road right?

 

the reason it says without locker on here is the people without the locker needed an alternative to the blue/yellow wire mod where you ground it and put a switch on it to disable abs to "trick" the truck into thinking ur locked so the abs doesn't work. i tried it and almost caught my truck on fire. anyway this will definetely temporarily disable abs on anything, w or w/o VSC/ATRAC. just cuts out the switch wire from the abs to the pedal. i have no idea whether or not it will disable VSC and/or TRAC though. anyone chime in?

 

and am i the only one that doesn't want any kind of traction control if i'm off road? i dont even care if it does work better. ha. i like being in control of whats going on where the rubber meets the road.

 

well, on bad roads I'd agree, but since I don't have a locker in TRUE off road situations, you can get stuck. Why would I take my truck off road? Maybe I dozed off and drove off road without hitting anything?

 

I did the tacogrande ABS/VSC/TRAC ground modification and blew a fuse when I was in 4Lo and I hit the rear locker switch. Can the rear differential be locked when the TRAC switch is turned on? or is the switch just for turning the TRAC on when in 4Lo unlocked?

When I am in 4Lo and have my TRAC switch on, the rear locker light comes on. I can't tell if its engaging or if its just the light. I've only tested it a couple times. Can the TRAC be turned on with the differential locked with this modfication or will I just keep blowing fuses?

The switch shuts off ABS, VSC and TRAC when the blue/yellow wire is grounded. It turns the TRAC on when the power is sent to the blue/yellow wire.

Except I blow a fuse everytime I try to engage the rear locker when the wire is powered. I should be able to use the locker with the switch.

Anyone know how to fix?

 

Way to follow directions from the link, I forgot to cut the wire...maybe that will fix it.

Just did this mod today and went pretty good. Only question is that I have a switch with a led on it and it only works when I hit the brakes with the abs on. Is there any reason that it doesn't stay on when I have it on. My brake lights work when the switch is on or off so not worried about that. Thanks

 

Anyone have a pic on which wires they hooked up to each terminal on the switch? Also do I need to ground the switch?

 

Yes. the wire you tapped into is from the pedal to the abs. its only hot when you hit the pedal. makes sense.

No you do not need to ground anything. unless you want a light to come on to let you know everytime you're hitting the pedal like ^^^^ that guy, but you probably know that. Otherwise you should have two wires. put one to the ground terminal and the other to the power out terminal. the positive terminal doesn't need to be hooked up at all.
