I am trying to find the @#$% thing?????
I actually want to find a location where I can insert a paperclip to jump to get the error code. IDK why it wont start:confused:
 
passenger side floorpan, pull the carpet back and there it is. Jump the 2 pin plug with a small piece of wire, but im not sure where its at on the CB7, sorry.
 
you don't need to jumper anything - just look at the flashing red LED on top of the ECU and count the flashes
 
the 1990 accord dosent have the light they started that in 93'as far as i know

Exactly my thoughts as well, my 92 lx didnt have the check light but had the jumper plug, and the codes were checked on the dash like a civic.

Same way in this thread

There is a jumper if you dont have a light on the ecu. I would look for a jumper first, if its there its a 2 pin plug and probally blue.
