jdm d15b in 91 crx dx
ok i need to know how to put it in i have already wired up mpfi acording to this(you will need to use the injector connectors from the D15B harness and mate them to your DX harness - cut the Main and Auxiliary injector plugs off your DX harness as close to the plug as you can - connect the yellow wire (not yellow/black) from the DX auxiliary injector to the brown wire on injector #1 (closest to timing belt) - connect the red wire from the DX main injector to the light blue wire on injector #3 - at the ECU, cut the yellow wire at pin A3 and connect a new wire to the piece still in the ECU plug and run it out to the engine bay and connect it to the red wire on injector #2 - at the ECU, cut the red wire at pin A7 and connect a new wire to the piece still in the ECU plug and run it out to the engine bay and connect it to the yellow wire on injector #4 - where you cut the DX injector plugs off, you will have a yellow/black wire from each - connect these together and connect to the yellow black wires from each of the injectors - this will get rid of the injector resistor - you will still need to run 2 wires from ECU pins C1 and C2 out to the distributor for the CYL sensor - you will need to add wiring for VTEC and for the 4-wire O2 sensor - you will need to swap the driver's side mount that bolts to your DX block onto the D15B - you will need to extend the wires that went to the cooling fan switch on the back of the DX block to the D15B cooling fan switch which is on the thermostat housing and also needs a different connector - you will need to disconnect the connector from the MAP sensor on the firewall and extend the wires so that the connector will reach the D15B MAP which is on top of the throttle body - you will need to extend the wires on the DX harness for the connector to the EACV, as it won't reach the location on the D15B - solder all connections) so is this all i need to do and wire up vtec and drop here in or wat

Its for an Si, but since u have it wired for DPFI already, it should be pretty similar from there...
