M275 Dual circuit brake upgrade question

[dilligaf13]

I'm currently restoring a M275 and came across a dual circuit brake system that I'm installing since my brake system was completely shot. I've looked at SMARPI 9-2320-209-14 and since it's based on a M35 chasis and not a M275 there a few plumbing questions I had on this upgrade. Most of it is matching up ok but I was wondering if anybody on here had done this upgrade on a deuce tractor yet?

One question I have is it appears as though a single brake line exits the top of the drive's side airpack and then splits between the front/rear and powers all the wheel cyclinders. Is that correct? Thanks for the help.

While I was looking in TM 9-2320-361-20 on page 4-45 (in the electrical section of all places) there is a picture of airpack and how to replace the stop light switch. In that diagram it shows the brake line from the top of te airpack going to the front and a brake line on the lower side driver's side closer to the frame going toward the rear duals. Anyone with some pictures or insight to confirm this would be appreciated. Thanks.
