[Lee M. Lemoine]

Ford used the "one line to the rear" method of brake modulation.  There was
a single brake line which ran to the top of the axle on my '89 Bronco 2
XLT...  from there it went down in a braided steel hose (rubber covered)
into a splitter with two sections of hard pipe to each of the wheels.  Each
of the front was on its own circuit.  May be worth looking into.  I know
most of the later-on GM stuff was 4 channel ABS (4 wheel independant)...

I may still have one of these units laying in my garage (4 channel) if your
interested.  It's off of a '93 Chevy Cavalier.  I should also mention that
all GM ABS cars use different pitch and thread fittings on each of their
connectors, so you will have to run all new lines, and flare them yourself
(32 degree double flare i'm remembering correctly).  Good luck!  (BTW: i
also have the ECM and pinouts for wiring for this unit..  I discarded the
wiring harness, but it can be had for little to nothing at any junkyard with
an 91-94 j-body in it...
