hey guys, i'm doing an obd1 ls vtec swap on my 96 civic ex. i've got the obd1 distributor, ecu and jumper. now, does anyone have a diagram or know which plugs to rewire to make the engine harness obd1? any help would be appreciated. thanks!

 

Hasport has a wiring chart for this. Another option is a JDM P73 (ITR) ECU. It uses OBDII plugs but is actually more like an OBDI ECU (but is actually neither OBDI nor OBDII).

 

you wouldn't happen to have the link would ya? thanks.

 

The distributor doesn't matter OBD1/2 distributors are the same with a different plug... Their firing order is the same unlike the difference between nonOBD and OBD1/2... The problem that you have now is you gotta repin the connector as the OBD1 style use two ugly connectors... OBD2 uses one big connector as you may have noticed on your Civic... If it came down to it I would actually cut the connector off your D16Y8 distributor and solder it onto your OBD1 one. By the way, is this basically an OBD1 LSVTEC (OBD1 distributor, alternator, injectors, etc.)?? If it is you'll have to cut all the OBD2 connectors off your EX harness and find OBD1 ones so that they plug on... If not then don't even worry about it... I'm pretty sure StorminMatt was talking about the jumper wiring on the HaSport site... That's all I know of and it doesn't do you any good as you already have your jumper... Here's the link incase you want it... OBD2a-OBD1 jumper pinouts Good Luck and let me know if you need anything else... Peace
