Need help! 06 Taco Trac Control

I was posting the above when you posted this - Give me some time, I'll look back at my mod instructions and give you a diagram.

 

You are the man!! Even if you can just let me know what you have wired to the common, the other two go to either switch leg.

 

OK, assuming your relay has the standard pin designations pins 30, 85, 86, 87, and 87a. If for some reason your relay is one of the odd ones out there with two pins 87, and no 87a, it won't work for this purpose.

Connect the "blue wire" from my mod (again, you can use whatever colour you like, but I'm going to call them by the colours I used to try to keep it easy to follow along with) to pin 30 of your relay.

Connect the "yellow wire" to pin 87a

Connect the "white wire" (ground) to pin 87

Connect switched power and constant ground to pins 85 and 86, or constant power and switched ground - whatever is easier, or works better for you - most switches with an indicator light will need to be wired switched power and constant ground to the relay.

Use a fuse tap in an ignition powered fuse to supply your new switch, and Robert will be you mother's brother

Set up this way, closing your switch will energize the relay coil, and disable your ABS. Open the switch, the relay coil is de-energized and normal ABS operation returns on-the-fly. The "common" wire here is the one going to the ABS module (I'm gonna call it the blue wire again), it is either supplied with +12V as factory wired, or it is grounded, either or, not both at the same time. Thus, no shorts to ground, no blown fuses.

This mod is hands down the best thing I ever did to that truck in the 6.5 years I had it, though I only used it off pavement.

 

Thank you, so very much man. So much for taking your time and writing all that up for me. I have been looking to see how to do this for several months! I wish there was a way to repay you man.. I am so very grateful!! You are the man!

 

I just wrote this up to hopefully help someone in the future who finds this thread. Also, if someone does find this in the future and needs a hand, shoot me or landphil a message and we will help you out.

And again, Landphil, thank you so much. I've been looking for this info for a good long while.

 

Diagram looks good, did you get it all wired up and working?

 

I ordered the AOB switches so they will be here tomorrow!

And no problem man, just pass on some help to someone else when you can, that would be repayment enough.

 

Not sure how I double posted...

 

Yessir, will do. I'm hoping someone will find this thread down the road and be as helpful to them as it was to me.

 

Hey bud I have a question for ya. I finally made it to my buddies shop to get this all wired up. I tested it last night during an ice storm and I simply snipped the wire and grounded it to make sure it worked as I thought it would,
and it did. (Speedo wouldn't work when it was grounded but no big deal) and it left it as it was (grounded) over night. I woke up, and hopped in my truck and with the wire still grounded and ABS was working as normal, as if the wire wasn't cut. I ignored it and came to the shop and wired it all up with the relay. The switch from Air on Board and the relay works and grounds the wire just as you said and the diagram I drew up but the ABS no longer shuts off. It's always on.. Any ideas?? It's like the computer by passed the cut wire entirely.

 

Are you sure you cut and tapped into the correct wire. Or perhaps you grounded and isolated the wires opposite of how it should have been? I never had any speedometer issues, or the other issue.

Is the speedo still not working? Check the Ig1 fuse, if it's blown, I'm thinking you probably reversed the two wires where you cut and spliced the wire to pin 4 of the IB1 connector.

 

Just to clear up confusion and misinformation about this, VSC was in fact available in 2006. What wasn't added from the factory until later, was the switch to disable it.

 

Yessir I am sure it is the correct wire, I looked at the picture in your post 10 times to make sure before I cut it haha Like I said, it worked just as you said yesterday (other than the speedo) and now today, with the same cut wire, it acts as if it is a completely factory Taco. I'm so lost. I checked to make sure if the relay is functioning correctly (it is) and triple checked the connections to make sure everything is correct. It has me beat At the moment

 

Thank you for clearing that up, I thought that was the case, but wasn't sure and had no proof.

 

Is the speedo working with the switch in either position?

 

I also thought maybe I switched the wrong side.. So I reverse it and blew a fuse. So it was correct. Damn truck is smarter than I lol

 

Well, there goes that theory...

 

The speedo quit last night when it was grounded, but this morning it works, along with Trac control even with the wire cut and grounded. No lights on the dash.
