Ok i just picked up a p28 and hooked up the conversion harness and pluged it into my 2000 HX. When i go to start it, it trying to turn over but doesn't. Also its throwing like 1/2 a check engine light, it comes on but not fully illuminated. Do i need to convert another part of my car to obd1? Any help will be greatly apriciated.

 

Please help. I think its the dizzy but i need some confermation.

 

battery dead?

 

u should be able to just plug and play with that ecu and car, are you sure u got the right conversion harness?

 

ditto

 

Yup i have the OBD2b to OBD1 harness.

 

I would recomend looking through the HX ecu pinouts if I remeber correctly some of the pinouts were difrent.

 

Ok i did some research and talked to some HX owners and some actualy said that it was OBD2a and not b. It really doesnt seem likely but im going to look into it.

 

hey dude it sounds like you have a bad ground

 

Ok i figured this shit out! Come to find out the HX is more of a bastard child than i thought. All 99-00 cars are suposed to be OBD2b right, WRONG!!!!!!! This car is OBD2a!!! So for all of you unfortunate souls that are working with a HX and are trying to convert to OBD1, get the A harness.
