this is the subharness that has the knock, O2, vtec oil pressure, vtec solenoid, and one other plug that I can't think of right now.

Question, what is the blue and orange wire for?

 

That is for a toggle switch so you can check what code it is throwing mate...that is once checking engine light comes on you turn the toggle on and it will start blinking.

that's actually my dad in the picture.

until you said something, I always thought they were some sort of messed up camouflage. He sport's those PJ's almost every day. Pull's it off quite well.

Back to the topic on hand...

So instead of checking the red blinks on the ECU for a CEL, you can wire the orange and blue to a light bulb of some sort that will throw CEL codes? Kind of pointless if you ask me To each his own I guess.

oh i see the blue and orange for your harness is the jumper switch. just solder or connected a on and off switch to it. this way you can check your engine codes when needed. Your check eng light will flash.

 

yup or you can pay little extra and they give ya the plugs with it and dont have to do anything lol like I did....

 

give ya plugs with it???

 

Its actually really nice. I just hook mine up yesterday. Obd1 crx. Works awesome. So much better then the old paper clip trick for the EG's. I flip the swith and boom it went to town. Flip it back off and the check engine just stayed solid like normal. Nice feature. Hook up a toggle switch. You wont regret it.

 

Just get a hondata and plug the ecu in to datalog for check engine codes it's the easiest thing ever and the best money I ever spent!!

 

no, dont give dumb advice to old threads. nobody wants to read your answer.
