Here mine, the main plug (white) has pink/black (12v+), black/white (ground), and brown (2k PPM to ECM). The second black plug with yellow wire is also a 2k PPM signal for cruise control. Yes you have to use the buffered signal for the green box.

Got it thats what i was looking for. I only have the white plug and it has a yellow wire instead of brown in it, since I only have cruise in 85. Thanks to all who helped out.
Glad we could sort that out for ya, makes sense now. My VSS was from a 1983 Malibu with the CCC system so it had an ECM and cruise, so 2 VSS feeds.
gm used 2 buffers a 3 wire output and a 4 wire output. the 4 wire was used in trucks with cruise control, both outputs are 2k pulses.these buffers are still available new from orielly's and napa
