Tubing Connections to 91's ABS Unit
Help! I finally got all my brakellines and the ABS unit out from under my car, and am now ready to install the stainless steel tubing. Does anyone know where I can find a schematic that shows the connection between each brake and the ABS itself. I know the unit was serviced or replaced before I bought the car (there was 15 cents lying in the cover!), but I'm not sure that it was put back together correctly. Therefore, before I re-plumb it, I want to make sure I'm doing it right. The unit is a Bosch-2, non-integral, which is correct for the car. The top right-hand port is ID-ed
as "h" and the port below it has no ID. On the left-hand side, the two ports on the top are ID-ed as "1A" and "JA" (I forgot my notes at the shop today so these may not be entirely correct) and the port below has no ID.
Any help will be greatly appreciated.

Right side with 2 total ports = rear input/bottom, rear output/top (h)
Left side with 3 total ports = front input/bottom, front left output/forward top (vl), front right output/rearward top (vr)

Thank you, BossHogg8!
Wish I had bothered to check my phone at the shop today... this would probably all make sense then. But no, this was a clean-the-wiring and rewrap-with-new-tape day instead!
