the gsr has butterfly valves and i dont think they are wired in the ek...

you need to rewire the ckf plug..... its easy.... i dont trust the ckf trick as its hit or miss on the boards...

the alternator plug is the same if its obd2

maybe the aic plug..... but mine worked on my 98 ex on my obd2 ls swap

the iat sensor plug needs to be swapped to b series plug

obd jumper is not needed if you stick to obd2 swap... but if you wanna run a obd1 ec use the jumper.... its better for tuning to use the obd1 ecu.... but you cant get emmisions with a obd1 swap...

injectors are alike...

buy obd2 swap and use a jumper harness to convert
