Re: OBD help swap
right or wrong??
i think you can leave the obd2 harness still on the engine and just plug right up to the harness at the strut tower, correct me if im wrong... and then just run a obd1 ecu a p75 or p28 well do...

Re: OBD help swap
Yes, if you have a '93 Del Sol Si, it should be a plug-n-play affair. Source a '94-95 Integra GS/RS/LS ecu (part number: 37820-P74-A00, 37820-P75-A00.. or versions up to A03) and you should be golden. Some '93's had the MAP sensor on the firewall instead of the top of the throttle body... if so, you will have to address that. There are three ways to do this:
1) plug the firewall MAP wiring into the throttle body instead of what is plugged into it from the engine harness... you may have to lengthen it a bit to make it reach... and it certainly doesn't look pretty.
2) connect a vacuum line from the bottom of the MAP sensor on the firewall to a port on the intake manifold... you may have to "T" it into something else like the cruise control or fuel pressure regulator.
3) unplug the MAP sensor wiring from the firewall area and route it over toward the passenger shock tower. clip the plug off and solder the appropriate pins to the three wires and insert them in the appropriate open locations that correspond to those of the engine harness. the colors may not match up, so you will have to take note of the position on the plug for comparison. this is the most difficult way, but it looks the cleanest.
Good Luck.
