Denver,
I have attached a photo of the non abs set up in my car.
Is this the same as what you have?
Why do you need to plumb into the lines at all? Why would you not just tee into the rear brakes straight at the master cylinder.
On the other hand I had a good look at Kim Ledgers Evo 9 and they had plumbed the braided cable straight down to the rear caliper and hooked it in there. Figured you could just tee straight off the back of the caliper.
Any other ideas?
