How to wire a Resistor Box for low impedence injectors

When you are piecing together a turbo kit to save money, it's hard to drop a few hundred on some RC injectors. DSM 450cc's can be bought for about $50. However, you will need a resistor box to run them. A resistor box can be found for about $10. The resistor box will make the injectors the correct impedence to use with your ECU.

Here's a diagram I made:

so then you just hook up the unstriped wires to the corresponding wire

sorry i mean no disrespect.. i just dont really like the way the topic is worded... maybe call it: How to wire a Resistor Box for Peak & Hold Injectors or (low impedence injectors)

cuz bigger injectors are NOT always peak and hold.. they make up to 750cc injectors that are still saturated(and do NOT need a resistor box)

I KNOW THAT YOU KNOW THIS ALREADY.. Just probably dont want to confuse anyone who doesnt know..

just a thought..

good luck with the site!! :D

thats a good point, I should say that when using the common DSM 450cc's you will need to do this. You can get the DSM's for about $50 If you bought a set of RC's (high impedence) for a few hundred bucks, you will not have to worry about this at all - just plug them in and go.

Thanks for adding and hopefully clearing this up for someone who didn't know 8)

here is a little something i made to help out. this is my 93 cx hatch with a b16 swap.


then put your power source wire and sensor pins back in and you should be good to go!!
