Hellooooo fellow Ef/Ed lovers. I need the pin out for the shock tower plug for the Dx STD model and if possible the one for obd1 civics also. I've been looking for them everywhere but no luck. If anyone out there has it please hook me up. U shall be rewarded with a big *** "thanks!!!", and knowing you helped out a fellow Ef lover. please help I'm going nuts looking for these!

 

Wasn't able to find a pin-out of that connector, but you should be able to find the manuals online and trace the wire colors off the diagrams.

 

The reason you can't find them is because everyone doing an MPFI conversion just adds a few wires and de-pins the connectors to perform the conversion. Using an SI engine harness on a DX car will not work without a shitload of drama, and that is IF you get the engine harness that is the correct number of pins, which is almost never the case.

look for a DPFI to MPFI swap tutorial in the FAQ, and it will show you the right way to do the conversion.

 

use your dx harness and add 4 wires..yes 4 wires. thats it. i even made my own lil plug for those wires so i can just unplug it when pulling the motor. it looks like factory.

 

having the pinouts won't be much help as the DPFI cars like the DX don't have wires from the ECU to the engine bay for the extra 2 injectors or for the cylinder sensor in the distributor - these are the wires that you need to add to convert from DPFI to MPFI - in addition, wires (yellow and red) for each of the 2 DPFI injectors from the engine to the ECU split inside the harness and become 2 wires for each injector at the ECU - this is why you need to cut wires at ECU pins A3 and A7 in order to connect the other 2 injectors

won't do you much good, but if you must have it, here is the DX connector pin-out:

 

Thanks a shitload for the pinout chart.

 

Thanks for the help guys but I mostly need it for diagnosis reasons.
