OBD2b to OBD2a
Has any one ever converted there obd2b cars to obd2a. I have an obd2a gsr harness in my 99 si and the harness in the car is obd2b. I am using a gsr obd2a computer. I don't want to have to repin the whole ecu plug so did anyone ever did this conversion. Any help would be greatly appreciated. Thank you.

Ibeleive any OBD1 ECU can be chipped/tuned for any application which is why that conversion is so useful

I am not doing this conversion by choice. If I had a choice I would put the correct harness and ecu in the car. The reason why I am doing it is because my car was stolenand this is the only harness I could get with an ecu. I don't really care that the ecu is chipped. Also I dont want to go obd1.

RE: OBD2b to OBD2a
I don't want to go obd1 and even if i use the harness I will still have the same problem. In the obd2b the green plug that goes to the car's harness has less wires than the obd2a. There is a difference between the two. I can rewire it but I dont have a honda manual so I can look at the wiring diagram for the 2 ECUs. If somebody could get me acopy of that I could do the conversion and post the correct procedures so the next person that does this conversion ( I don't know why they would want to do that) but they would have the instructions on how to do it. Oh and the only diagram I need is the one of the green plug for both versions.

Does anyone have a wiring diagram of the green harness plug that comes right after the ecu plugs? I need the diagram for both obd2 ecus. Btw its the plug that links the harness to the car. Thanks.

Well since nobody on this board knows anything about automotive electrical wiring, I might as well solved my problem myself. I thought sombody would atleast done this conversion before but I guess I was the first to actually do an ecu swap without buying a harness conversion. It was fairly easy to do and took me 30 minutes to do. I must be one of the only good techs on this site. Well anyways Im selling harness conversion kits So let me know what you need and I'll see ifI have it orI can make it.
