You need to put a line directly from the proportioning valve to the rear line, and a T in the line for the front brakes. You can then remove the entire ABS block, and light bulb. The fittings should be either double flare, or bubble flare. The OEM parts are bubble flared. Bubble flared lines will be compatible with the OEM type, and can be easier overall. I make bubble flares by performing the first step of making a double flare, and using them that way. I chose to shorten the lines, and connect them as directly below the proportioning valve as possible. Put some loops in the line to allow for flexing like the OEM lines. The only issue is getting into the limited space available.
