I did find on the buickforums.com that the '96 Buick Roadmaster was the first year was OBDII compatable. Previous years had OBD1.
Obvously these diagnostics are very helpful, but can anyone speak to questions I have:
1) Since the OBDII diagnostics are more capable, do they also add difficulty when performing an engine/transmission swap to a different vehicle?
2) Will I have to also swap more systems from the donor car in order for the engine/transmission to work properly.
3) I had planned on swapping the instruments as well. Would OBDII make this more difficult to swap?
