Ok i have i set of odb1 h22 injectors i would like to install on my B16 motor in my 92 DA what all do i need to do to install these besides re do the clips with ones that fit the injectors? I heard some where that i need a resistor box but which box and where do i wire it in at?

 

Crx resistor box will do the trick

 

i can use prelude one too right? also when wiring up the box to the injectors which wires go where?

 

resistor box depends on what h22 injectors they are

 

OBD1 345cc H22 injectors are peak and hold and require the resistor box.

The colour wires from the injector clips go to the ECU as they are already and the power wires are the ones that you cut and splice onto the 4 black resistor box wires.

 

Thank you for the diagram, very helpful.

 

Just to make sure there is no confusion. The stock power wires going to your injectors are probably YEL/BLK not RED/BLK like I have pictured above. It is still the same basic wiring just different colours.

Note.
You only need one of the original YEL/BLK 12v power source wires to splice onto the RED resistor box wire as indicated above. You do not require all 4 spliced together. Remove, tape up or cap off the other three that you are no longer using.

Good luck

 

not calling you dumb or anything but just for safetys sake you know you need a retune when going with larger injectors right
