I got a 99 dx civic automatic engine harness that i need to convert to a bseries harness.......... i have try to do some research but i get very confused. Is there any simple way of explaining exactly how to and what to go about doing to make this harness compatible to a bseries motor?

the motor is up and running in the car but i am currently running an engine harness out of a 97 in a 99 chassis making the cabin harnesses not match ( pinouts dont match) up to the engine harness which i think is causing my speedo and fuel pump not to work?

i am hoping that since the 99 dx engine harness matches up exactly with the cabing harness may fix the problem but i would need to convert it to b series first........ any help will be greatly appreciated, thanks.


Also, i purchased a used obd2b to obd1 jumper harness that came out of a 2000 ex civic but two wires have been spliced. he claims that one is for the vtec and the other is for an oxygen sensor?
