in a ef with a b series obd1 swap... how do i get it into diagnostic mode... it has the ecu adapter but not sure if it has the diagnostic plug... also anyone kno where i can get a breakdown of the ecu pins and also the daignostic codes so i can trace some wires... i think its wired wrong... im getting a cold start... its hard to start and doesnt stay on until its warmed... i wanna trace the coolant temp sensor back to the ecu... thanks

 

your jumper harness will have extra wires that can be hooked up to a toggle switch.you use your cel for codes.

 

any idea which wires it would be

 

i also need to kno the layout of an obd1 ecu
