Hi HT!

I have an obd2 ecu harness and thinking about converting to obd1. What are the things ill need? Is it just a plug and play thing or i have to rewire other parts too? I have no idea on what i should do to convert it to obd1 or will it be easier if i stick to obd2 ecu instead?

Any help/suggestion is greatly appreciated

 

depends what you are trying to do.
depends if you are obd2a or obd2b.
google my friennd. theres much color photo tech on this out there

 

Obd2a is what i got. Not really looking up to tune my car itll stay what it has now since its my dd anyway. The only reason i asked is because i have 5speed with auto ecu on it and planning to buy a new ecu just wanted some info before i purchase it. Thanks!

 

Buy the correct ECU for the motor you have. An OBD1 will not pass emissions either.

 

Thanks i think im just going to stick to my obd2a p2p then and also since i am in washington we dont have emissions. Well thanks again!
