How do you wire up an injector resistor box?

[G3-TEG]

Anyone have a wiring diagram on how to install a resistor box on a high impedance (saturated) b-series motor?

Assuming you are using a honda resistor box.

Thanks.

No diagram...
But I can describe it.

Simply run your 12V+ source to the input wire of the resistor box... and then each of the four remaining wires to a corresponding injector. The GROUND wires from each injector trace back to the ECU.

Thanks Jim.

Sounds easy enough.. Just to clarify, the 12v source can be any ignition switched 12v source correct?

And each of the 4 remaining wires from the box goes to each of the injectors - meaning instead of the original 2 wires that go into each injector, the GROUND remains going to the ecu, but the power is CUT and now runs to the resistor box, leaving the original power wire unattached now?

Would that be correct?

Here would be MY suggestion:

Trace the four 12v+ wires coming from each of the four injectors until you find the common wire that they originate from. Cut the four injector wires from this point and then connect them to each of the four output wires in the resistor box (you may have to extend some or all of the injector wires). Then connect the original 12v+ feed wire to the input wire of the resistor box. This inssures that you will be using a suitable reference voltage source for the injectors.

Does this make sense ???

Ahh.. yup, it makes total sense.

Basically I will be splicing the resistor box into the existing injector wiring.

Where the single 12V source wire branches into 4 wires (one for each injector) is where I will splice the resistor box. The original 12V single wire will feed the 12v input wire on the res. box and each of the 4 wires coming out of the box will go to one of the 4 wires that was original cut in the existing harness.

Voila?

to run peak-hold instead of saturated injectors.

It's powered by GASOLINE damnit!!!

By Joe... I think he's got it !!!

This makes me think that maybe I would be smarter to just put ONE resistor in line for all four injectors instead of having 4 resistors with one on each injector harness for my setup. Although I bet having 4 of them helps with thermal management some.

Your using resistors rather than the OEM resistor box?

What size resistors?
