I have a line lock on my rear wheel only ABS truck so it was easy for me. In looking at other guys 4w ABS trucks (because they asked me about it) it looks like you'd have to use two line lock solenoids to make it work rather than one. You need to have the line lock on the brake side of the ABS controller. On the 4w ABS trucks it looks like there are seperate circuits for the left and right front brakes and one for the rears (3 circuits total). Therefore you'd need to put a solenoid on each of the front lines wired to one switch. Hopefully someone here has actually hooked one up and can tell you more. The other possibility if you are using it for racing purposes only then you could pull the fuse for the ABS to disable it (from what I've read on here that will also disable your speed - don't know about the tach) and then have the solenoid before the ABS controller.

Scott,



You don't need line locks as you aren't even a DHRA member... . :{

Steve my truck is rear wheel only ABS, could you please tell me how to install the line lock.

I bought a TCI roll control and a hurst install kit from jegs. The install kit came with several brake lines. I took a piece of flat and made a bracket to attach the roll control to an existing bolt. near the proportioning valve. I found a local shop that had a double flaring tool to put the ends on the line and arranged to have them do the ends. I installed the roll control solenoid and the lines in their parking lot. I cut the stock line on the brake side of the proportioning valve and had them put a double flare on it, then installed the roll control. I bent the line from the hurst install kit to fit, cut it to length and had them put the double flare on the other side of it. Then I bled the brakes in the parking lot (used the gravity method - just opened the bleeder and kept the master cylinder full until no more bubbles were coming out). I put the switch to activate it on the shifter in the truck, ran 12v to the switch, then a wire from the switch to the solenoid, and grounded the other wire on the solenoid. That's it. Here's some pictures of the installation:
