Is this what you are looking for? FWIW I did this and am now thinking of putting a switch in where I cut the wire giving me the option of disabling the ABS/TC in the rare event I'd want too. I haven't heard of anyone else doing it that way but I may become the guinea pig.

Cheers,

Mike

1) Disconnect the battery. Unscrew the four hex screws in the glove box hinges. Reach round the side of the glove box with each hand and pull the closing mechanism upwards. Slide the glove box out

2) Pull out the 3 push-studs on the black cardboard panel underneath the glovebox, and undo the screw stud at the back. Remove the panel.

3) Near the outer side of the gap behind the glove box, you will see 2 or 3 ECUs, depending on whether you have ACE, I think. The SLABS ECU is the centre of the three, or the outside of the two. It has 5 black connector blocks underneath. Remove the centre block of the five from underneath the ECU.

4) Look for the black & blue wire running to pin 9 of the connector block, which is the central pin on the lower row, i.e. the row furthest from the retaining clips. At this point, make sure you have the right connector, and the right pin!

5) Cut this black & blue wire & tape off the ends. (Give enough space to solder it back together if you find out you have cut the wrong one...) Reconnect the connector. Replace the panel and the glovebox. Reconnect the battery.

Please note :

This is not needed for 2003 on (facelift) models as the ECU has been reprogrammed to take care of NOT disabling traction control/ABS when CDL in engaged, when ignition is switched on.

To test: engage the CDL and start the car up. The CDL light should be lit, but the ABS/TC lights should not be lit up. This is correct - it means that the SLABS ECU is not disabling ABS/TC when you start the car up with the diff lock engaged

I'd be interested in your switch experiment ... I didn't snip any wires, but I like the flexibility of a switch ...

I snipped the wire, works great.. been almost a year, nothing negative.. just the fact I can turn my truck off and back on without having to activate/deactivate the CDL..
