thanks for all the help guys

 

anyone know how to do this?? just need to know why i have check engine light need to check codes dont know how because of the swap

 

thanks bro for bumping the post if we cant get it running well have to go to autocrafting thanks for helping with the swap as much as you have have fun in long island

 

did you guys hook up a toggle switch? this is how i check my car if it throws any codes.

 

no we didnt how do you do that???
tell us how and do you have code sheets?

 

I'm not sure how you converted to OBD-1, but if you did the wiring yourself and did it correctly OR if you got a quality jumper harness then it's really easy.
You just put a jumper (paperclip) in the 2 prong connector under the glovebox.
It's the same connnector you put a jumper in when you go to set the ignition timing.

Search Yahoo! for HONDA ECU CODES and you should find MANY links to what the codes mean.

 

i bought a locash racing jumper harness with dizzy adapter and subv harness for vtec

 

on my harness there is a wire running from the jumper which can hook a toggle switch up to, ground the toggle switch and when you have a cel you switch on the toggle switch (ground it) and it will show you the code. that would be the same thing as jumping it with a paper clip but instead of using a paper clip you are using a toggle switch.

 

ok we did it got code 4 and 41

 

bump for help
