Ok, I'm confused now. I've got a 10AE. it's got the red injectors. I just bought a set of 720CC injectors and was told that they'd hook right up. they look exactly like the ones in that picture, blue caps with black overspray on them . What modifications does my car require?

Then your system is high impedance and you will need to install the resistors.

Here's a link to what you need: http://www.radioshack.com/product.as...5Fid=271%2D132



$1.79 each and I bought a plastic box with a circuit card for a few more $$.

Then just tap it into the secondary injector wires at the ECU, mount the box up in your dash somewhere.

Thats all there is to it--good luck.

but you have an s4 with should be low impedance injectors. I have an 88 with no resistors but it looks like you have one with resistors??? I'm so confused.

FYI: I just noticed the pic has a 2 watt, but the link is for a 10 ohm / 10 watt resistor. Make sure you use at least a 10 watt preferrably 20 watt resistor if you can find it.

So you have an 88 then. You must've missed my earlier post...
