How to build a conversion harness for a Honda VX (p07) ECU
<style type="text/css">
<!-- .style1 { color: 1; font-weight: bold; } .style2 {color: 1} --> </style> <p>This is for the people who want to put a Honda Civic VX Engine/ECU into their obd0 Civic/CRX (1988-1991). This writeup is assuming you are using a MPFI ECU/wiring harness. This comes standard on the Civic EX, the CRX Si, and the CRX HF. If you have a Civic STD, LX, DX, or a CRX DX you need to convert to MPFI before this harness will work. There are plenty of write ups on the internet on how to switch from DPFI to MPFI.</p> <p><strong>What you need:</strong> You will need the female plugs from an obd0 ECU. I recommend going to the junkyard and finding a pm5 ECU from a Civic DX or LX. Rip out the female plugs from the ECU and desolder the connections. You will also need the male plugs from a obd1 civic. ANything made between the years of 92-95 will do, but might require a little modification. If you are lucky and can find yourself a Civic VX in the junkyard I'd recommend taking the ECU plugs from it as the wires are all there.</p> <p>Assuming this is all true, make a conversion harness using the pinouts below:<br> <table width="100%" border="1"> <tr> <td> It seems that some of the pinouts were incorrect. I just ordered a conversion harness from a company that specializes in them. I will reverse engineer the pinouts and upload them here at a later date. </td> </tr> </table> |

i got some of the wires u dont have (egr for ex.) i'll get the wire collors. also the missing colors on the obd0 side are: injector is yellow, egr control is red, egr lift is yellow. if u give me a list of what u need i'll look for ya.
