Question: are all the pinouts the same on OBD1 ecu's. I having trouble locating pin outs for H23A but lots of GSR stuff. In particular i'm looking at the secondary intake runner pinouts.
The GSR pinout is A17, can i use the same A17 on the H23A ecu?

 

Are you putting a B18C1 into a Prelude/Accord?

 

go to google.com and do a search for "honda ecu pinouts"

 

you can also just drive to the honda dealership and talk to one of the techs, they have all the manuals there and if they aren't busy some of them will let you make copies of certain pages

 

Thanks
