I know I will probably get bashed for this post but after trading around I ended up with this usdm H22 super cheap. I figured what the hell Ill slap it in no problem. I have all the parts to put it in my 89 CRX si. After much reasearch on this swap the last of my research ends at the resistor box. I have a p13 ecu, using stock injectors, and my extended 89 Si harness. Do I use my Si resistor box, an OBD1 resistor box, or cap the end plug like? While im doing this swap I will post my complete process with pictures . I know not many people are doing this swap but it would be nice to share my swap with others to make it easier. The info I have found on this swap doesnt cover everything. Hopefully I can help out the next guy.
