I am wiring the vtec solnoid, the knock, o2 and oil to my cpu although my dx wire harness already has wires where there suppose to plug do i just cut and attach or do i need the wire that is alread there? please help thanks

 

need more info to help. what motor, ecu are you swapping in? sounds like a B-series VTEC motor? and are you staying OBD-0? or are you using a conversion harness if you are switching to OBD-1?

 

you an cut for knock and vtec and press. 02 i belive needs to be "spliced"

 

I got it thanks court, the knock, vtec and press were the ones i cut i had to add the 02 to the harness as a new pin next question would be how do i get my dpfi to a mpfi, or for a dx to a sir or a d15b to a b16a :D

 

cut c1 and c2
they are for your dizz

c1 is blue with grn
c2 is blue with yel

you also need to move 2 other pins....


do a search on dpfi to mpfi

 

I think i might of found
In order to convert your dual point injection DX to multi-point injection you will need 4 injector plugs, an injector resistor box, extra wire, a wire stripper/cutter, heatshrink and/or electrical tape, and some patience. Also, when doing this conversion I would highly recommend soldering all connections and heatshrinking them. If you do not have access to heatshrink neatly wrapped electrical tape will do just fine. It is also extremely helpful to have an extra multi-point injection engine harness laying around to take plugs from (i.e. injector plugs, injector resistor box plug, and distributor plug). Listed below is a straightforward and easy to follow set of instructions to help you complete your DX to ZC swap:
DX to ZC
Inside car at the ECU plug:

Pins B10 and B12 are empty. Unused pins can be taken from B2 or B11. Some models have a wire located at B12.
Cut orange and white wires off at C1 and C2 and connect them to wires added at B10 and B12. Orange-B10. White-B12. Leave enough wire for next step.
Run wires from C1 and C2 (direct ECU connection) into the engine compartment. Label these wires for later use.
Cut wires at A3 and A7 leaving plenty of wire. Run these wires into the engine compartment and label them for later use.
Outside car

Transfer DX wiring harness over to ZC engine.
TPS and EACV plugs are too short and must be extended.
Be sure to switch green/white and yellow/white wires on TPS
Injectors and injector resistor box

Connect the yellow/black wires from the two DX injector harnesses and run it to the yellow/black wire on the injector resistor box.
Connect the yellow wire from the DX injector to the #1 injector (brown wire).
Connect the red wire from the DX injector and run it to the #3 injector (blue wire).
Connect the A3 wire to the #2 injector (red wire).
Connect the A7 wire to the #4 injector (yellow wire).
Connect the 4 red/black wires from injector resistor box to each injector.
Cylinder position sensor

Connect C1 to blue/green wire on cylinder position sensor plug.
Connect C2 to blue/yellow wire on cylinder position sensor plug.

 

thats it. if you follow that exactly youll have no problems. it only takes like an hour once you get it down.

 

I found all that off of the site, I also have already wired the solnoid, o2, pressure, and knock to the ecu and the wires are just hanging in my engine bay i have each of the marked which is which, so my next question would be where do i connect each of them at in the engine bay, i.e where is the solnoid, knock, o2 and pressures wires that i connect them to and if you have any color codes that would help, also where can i find the cylinder position sensor on the car to wire the c1 and c2?

 

wire them directly to the sensr
ckp 's are on the dizz harness. they are both white I belive.
