Help with talking to 1995 4.3 "W" NON J1850 VCM

[EK]

Greetings,

FNG here needing help trying to figure out what will talk to the oddball 1995 flash based VCM-A on a 4.3 W vortex motor, 5 sp stick, 4 wheel anti-lock. This thing has a OBD2 16 pin DLC, with all the right pins stuffed for J1850, but won't respond to at all from B&B Electronics OBD2 AT1 Autotap. Sticker underhood says OBD1 compliant. Anyone had any luck or know if the Rinda Diacom stuff or a custom programmed Hughes Auto Xray unit will talk and/or give anything useful? Both of these units only seem to support 12 pin ALDL. Is a 12 to 16 adapter all that required for either of these to talk? BTW, the B&B unit does give plenty of useful info back on a 1999 OBD2 full size truck, including ability to clear trouble codes.

Eric
