I have a 90 civic dx, d15b2 dpfi, I’m doing a mini me swap with a y8 head and y7 injectors every where I look it says to wire injectors to ecu a1,3,5,7 ports and then to the resistor box but my car doesn’t have a resistor box nor a spot for it on my wire harness do I need to run a resistor box with high impedance injectors like y7? If not how do I wire the injectors?

do NOT use the d16y7 injectors. They are 190cc, and not the normal 235/240cc size you need.

Unless you are trying to learn about lean detonation and its effect on piston ringlands.

any of the MPFI conversion harness's have pinout diagrams.

a simple OBD0 ecu pinout diagram will help you get it done.

There is far more than just the injectors to wire up.

And nope, you do not need a resistor box with high ohm injectors. Test each individual injector for 12-16 ohms.

But depending on the ecu you are going to run, no matter what, if OBD0 or OBD1, you will need different injectors

you want to do wiring and conversion shit, yet dont own a simple multimeter? 5-10 bucks at harbor freight or walmart.


Good luck on your adventures.
