Hey guys I'm in the process of making a obd1 to obd1 harness so that you wont have to splice into your harness. When i'm done i will be posting the how to so you can make one. Oh im using the p30 ecu pinout so this will probable benefit b16 users and type r cause i know the gsr has extra wire that you need. So when im done ill let you know how it works.

 

FInished harness it works fine. Who wants one

 

from what i've seen apexi is selling these as directly plug and play harnesses

 

Apexi makes harnesses for other cars, im not sure if they make one for OBD1 Honda's.

So you made this harness in a day and it works good? Wheres pics?

 

Ill post pics The heat shrink i used wasnt the best but it worked. I would do a write up but I figured that everybody on here already knew how to make one.
