Wire Action
A3 cut, connect ecu end to Injector #2 wire on First harness
A6 cut, use harness end later
A7 cut, connect ECU end to Injector #4 wire on First harness
A8 add, connect to VTEC solenoid wire on Third harness
A10 cut, connect ECU end to harness end from A6
B2 cut, we will use harness end later
B4 cut
B5 cut, connect ECU end to oil pressure switch wire on Third harness
B7 cut
B10 add, we will connect to this later
B11 cut
B12 add, we will connect to this later
B19 add, connect to knock sensor wire on Third harness
B20 leave alone
C1 cut, connect harness end to ECU end of B10 above,
connect ECU end to crank angle sensor wire on Second harness
C2 cut, connect harness end to ECU end of B12 above,
connect ECU end to crank angle sensor wire on Second harness
C8 cut, connect to second O2 sensor on Third harness
C9 cut

 

ok.....what are you wiring up??

 

b16a jdm to a 88dx

 

obd-1 or obd-0??

 

ok im putting a b16a into a 1988 crx dx it came with the wiring harness for i bought the whole swap, I have a couple questions at this point after i have already wired somethings.

I so far have wired
- A8 to my vtec solnoid
- B5 to my solnoid pressure switch
- B19 to my knock sensor
- C8 to my 2nd o2 sensor
- I swithed my C1 to B10 and C2 to B12
- I then ran new wires from C1 to the blue/green wire on my distributor
- As well as C2 to the blue/yellow wire on my distributor
- I ran A1 to injector #1 (Brown wire)
- Then i ran wires from A3 to #2 injectors(red wire)
- From A5 to # 3 (blue wire)
- From A7 to #4 (yellow wire)

I already have the engine harness that plugs to the resistor box into the injectors so do i still need to cut the red/black and connect them straight to each injector or are they okay since i have the harness that goes straight to them?

 

Oh yes it is OBD-0

 

Sorry i gotta get this motor running theres alot of money into and i now someone out there can help me out so imma do a little bump

as far as this questions goes. if you are using the whole harness that was giving to you w/ the engine I do not know....
But if you are using your old harness where as you would only need to add a couple of wires then...You would plus the red/black wires coming from the injectors directly to the resistor box. Yellow/black wires connect that one directly the the dash harness which leads to the inside of the engine bay and then the correct positive wires from the injectors directly to their designated ECU wires/pinouts

 

well my car wouldnt start and i figured why i was using the b16a engine harness with the dx chassis harness so it was telling everything in my engine to do the wrong thing But i am working on the old dx harness I have already did my dpfi to mpfi and all the wiring is done at the ecu so it should be running by the end of the day

 

yeah that's the best way to do it. Just use the your original harness and just add the needed wires which should only be 2 extra wires from the distributor, then you have to switch around to existing wires from the distributor. 2 wires for vtec and then the two extra wires from the injectors...and there might be one more that i can remember off hand..

oh yeah switch around your tps wires. the two end ones. i believe the color is green and white
