can anyone explain exactly what a conversion harness is. does it convert the harness on the motor or the one in the firewall. can anyone recommend any good websites with wiring info

you need to start with the DPFI to MPFI swap
use the search function and enter in MPFI and search in this forum and make sure you search the archives. you'll find a **** load of stuff and solutions to any problem that you might have

 

see the dpfi is only 2 injectors and the mpfi is 4 injectors, so you need to convert from 2 injectors to 4 injectors, its not really that hard, its only runnin 4 wires to the ecu then another 4 to the resistor box, and lengtening a few wires

and since the gsr is obd 1, you either gotta convert yoru car to obd 1 or convert the motor to obd0. if the gsr motor is obd 2, well thats not even worth the hassle, just convert the motor to obd 0

 

If you are serious about this, I think it might be easier for you to get a wiring harness from whatever car your engine came out of, get the integra gsr gauge cluster too. Do you have the ECU yet?? The obd-1&2 computers have different connectors from your current setup and for the amount of wires you are going to have to add to make it obd-1 or 2, you will almost have to create a custom wiring harness, if not then a really extravagant adapter harness. There might be issues with certain items if you try to turn your b18c to obd-0, you may need a new distributor, injector resistance, etc

 

contact Hasport, they have the conversion harness to change it over.
It will probably be the easiest to do since you don't already have an HF or SI harness
