Ok a couple things, If I go from a OBD2A to an OBD1 will I have to change anything one my car for compatability reasons, like the injectors or distributor maybe. Second I have a P28 that was converted by hondata to an OBD2b (not with a harness, they physically soldered in a small conversion board). Anyways I have a 96 teg ls/vtec that I want to put the P28 in. I should be able to just buy an obd2a to obd2b conv harness for that right? Thanks.
