Power and Ground Wiring.
Modified Flash to eliminate engine errors.
Serial Data to figure things out.
Likely the 1998 pickup VSS output will need spliced to provide two outputs. One output spliced to a DRAC so the 16197427 will have a VSS input and the original VSS output to the 16258825.
I'm not sure going OBD1 is the best option for the 1998 pickup. I'm thinking the option of fixing the 1998 with stock parts (spider assembly) would likely be less work and less money than an OBD1 hybrid solution? I'm thinking perhaps the OBD1 hybrid option makes more $ense if the 305 was being removed and replaced with a "Performance" OBD1 engine.
