ok so i got a d16z6 and im putting it into a hatch witch of coarse is dpfi. im converting it into mpfi and i was told you dnt need a resistor box for these injectors. so how would i go about the wiring on this set up?

 

Anything guys?

 

Ready? Here is the ECU connections - https://honda-tech.com/zerothread?id=1319235
VTEC Solenoid - Run to ECU
VTEC Pressure Switch - Run to ECU - Ground at thermostat housing
Four Wire Oxygen Sensor - Run Oxygen Content to stock wire (shielded)
- Run heater to ECU
- Ground both at thermostat housing.

 

thanks. so am i going to need a resistor box? oh yeah im using an obd0 ecu and using the dpfi wire harness

OBD-1 & 2 injectors do not require it.

 

good someone finally answere my question. Sense im wiring it into the dpfi harness where would the other wires go? wait but wont it only work without a resistor box if i was only using the obd1 ecu? thanks your very helpfull

Don't ask me which one requires the resistor box as I forget all the time. If you are doing it with a DPFI harness first follow a guide for MPFI - I recommed Fourth-Gen-Hatch's - http://www.gutterslide.com/fou....html. From this point, find an install for a OBD-0 B16 and you should be set. Just FYI, you can't use the D16Z6 distributor with OBD-0, you will need to modify your A6 to work. You can use your stock oxygen sensor as well, but a heated Oxygen sensor allows you to change your placement of the sensor in the exhaust tract without worrying about the readings coming off wrong as the sensor is cold.</TD></TR></TABLE>

 

ok the obd1 injectors still got two wires going to them i know where the left side wires go but where would i wire the rightside of the wires if i dnt need a resistor box?

 

Note: Removal of the engine harness is recommended due to it making it easier to modify the harness. Wire colors will be listed in this manner red/grn (this means red with a green stripe). Many wires can be pulled out of plugs by pushing in the front (with a small screwdriver, etc) and giving a gentle tug on the back of the wire.

1. The injection resistor must be removed from the circuit. This is because the OBD0 injectors are not compatible with the OBD1 ECU. In order to do this, the yel/blk wire from the green plug on the injection resistor must be pulled. It will be relocated into an open space in a gray 8 wire plug from the OBD1 harness. This OBD1 plug has 8 yel/blk wires leading out from it and has a gray cap on it. Removal of the cap shows that it has an integrated metal clip that connects all the yel/blk wires together.

2. Injector wiring. To use the OBD1 injectors, the injector plugs from the OBD1 harness must be used. Each plug has a different color line (brown, red, light blue and plain yellowÂ…1,2,3,4 injectors respectively) and a yel/blk wire leading from it. The yel/blk wire from each of the injector plugs leads back to the 8 wire plug mentioned in #1. The OBD0 injector plugs must be cut off and the OBD1 injector plugs soldered on. Match the injector colors to each other, as they are the same on both the OBD0 and OBD1 harness. Note: On the OBD0 harness, the wire leading from the injector plug to the injector resistor is red/blk. These wires need not be worried about as they only connects the OBD0 injector plug to the injector resistor.

 

ok then i allready did the wiring but sense all the grounds come together at the grey plug from the obd1 harness (8 wire conector) where does it ground isnt it suppost to ground through the pcm or something?

$300. Done right. OBD1 - we need your DX harness and a z6 harness.
I don't support OBD0 z6's unless they use a pr3/pw0 ecu chipped for the sohc.
