alrighty my 1998 civic EX GSR is obd2a. i know there's a harness to convert it to obd1 but is it just a simple "plug-and-play" or do i have to re-wire a bunch of things in order for my tuned obd1 ECU to work properly without throwing CELs all over the place...?

im not realy knowledgeable when it comes to ECUs or harnesses so don't flame TOO too badly lol

help would greatly be appriciated.

 

Plug-and-play, assuming you have the correct harness.

 

thank you!
