A13 is the wire for the CEL on OBD1 cars. Seeing as my EF lacks the diag. jumper, I assume wiring a 3 wire switch grounded to body will make the CEL's flash on my instrument panel.


A13----->-------Switch-------->------A13------>-------ECU

LOL that work like ----, just turned my CEL on and off, durrrr

what other wire needs to be jumped in junction with A13? No schematic I have shows it. I need to download the PDF for a EG

Bump, stayed up all nght going thru schematics, found nada


What u know bout this chris?

I'm pretty sure you just have to ground it out.

blackice90hb

well I did that and all i did was turn the light on/off. Maybe I did it wrong,

should it be like this:


Dash-------------->--------------A13--------------------->---------Ecu before

Dash-------------->---------------A13------------------>-----\ disconnected---Ecu
\
\
Body ground

EDIT: D4 is the pin for the service connector, I'll try grounding that instead. I'm wrapping up now to brave the frigid 50 degree temperatures of the Florida coldness. Will report findings when I come back inside, provided I dont die of hypothermia, or carbon monoxide poisoning

or
Dash-------------->--------------A13--------------------->---------Ecu, Unbroken wire

wow you know i nevr thought about how to check cells on an obd1 converted car. you should sticky this if yo find out how, im sure someone has needed this info before.

LOL i was so desperate I took out the conversion harness and plugged in my PG7 just to see if it would flash a code. It didnt

Well after fixing 3 pins on the "NEW" pos Rywire conversion harness i bought from a member here, and catching ------itis after a big lunch, I'm awake and ready to plug all this ---- back up. JLICRX on hondaswap tells me that D4 is the pin for the service connector for OBD1. So in the spirit of common sence, i came up with this:

ECU--------------->D4-----------=======----------->-----A13------------>-------------CEL on dash

On Eg's when the jumper is shorted, the cel flashes on dash, so If I have the circuit for the MIL and the Service connector, feeding the MIL off the serv. conn wire should make it blink accordingly

well bitches, my car is trowing a 41 and a 16.

All that is needed is to short out D4, not A13

46 is system to lean/rich, 16 is a injector code. I noticed the car was running rich for the past couple weeks, i figured the o2 was on its way out. The code 16 is baffling to me because when I first got this hatch, when it was still DPFI, it had a code 16. Now im on a different harness, engine, ECU OBD1, and im seeing 16 again. I know for a fact im long overdue for a Fuel filter, but that wont cause the ECU to throw a code...maybe a lean code, but not a injector code.
