I replaced the abs hydraulic Control on my truck and I think I messed up the lines that come out of it. There are 3, 1 left front, 1 right front and the 3rd to the rear. They all go down the left side by the wheel well. Does anyone know where I can find a diagram of which is which?

2002 3500 4x4 with 4 wheel abs.

Thanks

Quick update, when I stand on the brake pedal, the rear locks up.

Thought the service manual had something, but it doesn't. Here is a printout from the parts manual, not much better, but you might be able to figure something out.

Thanks, I got the lines straightened out, bought new from dealer. They only go in one way. Problem now is the rears are locking up under hard braking and it does not seem like the fronts are working right. ABS light comes on after hard braking (abs not activating), no codes and light clears on a restart. I am thinking possibly the combination valve or master?

I'm watching. My right rear locks up under light braking and ABS does nothing.

when I put my disk rear axle onto my old 1995 I was super worried about one wheel lockup as the sensor is on the ring gear- so as long as one rear tire is spinning the abs thinks all is good... lucky for me my abs sensor dropped right into the new 2002 axle and is performing perfectly.

That's a specific brake issue at the wheel, as has been said, the rears are a single channel, so your ABS doesn't even see 1 side locking up without the other.
