Default I inherited an EMU and injectors...

But, the injectors are low impedence, 3.8ohm. I plan on going to radio shack to pick up some 10ohm resistors and wiring those inline. My question is which of the two wires in injector plug harness do I splice them to? I have tried searching and I keep coming up empty.

Thanks.

You have a '96, yes? Then you have four injector wires currently going to your ECU. You will cut each wire in half, the half which goes to the ECU shall be connected to the EMU's "IN", and the half which goes to the injector will be connected to the EMU's "OUT". The resistor shall be placed in series with the "OUT" wire. So:

Thanks Joe. I have a boomslang as well. Maybe I should have metioned that. I dont have any manuals other than the operation manual and the CD.

Then ye shall have the installation manual as well, that the wiring might become obvious: http://greddy.com/img/PHP/products/pdf/806.pdf

Long story short- I've never actually seen a BS harness, and I understand that every single wire on it is the same color. You need to identify the four wires that are the Injector to EMU connections, on pins C34 (1), C35 (2), C36 (3), and C42 (4) and that's where you'll cut and install the resistors.

You are freaking awesome. I also changed my sig to better identify my car and set up.

Thanks.

My awesomeness is indeed great.

Seriously, it shouldn't be too hard. Just be aware that the resistors will get plenty warm in operation. They should ideally be rated for at least 15 or 20 watts, and located in an area where they cannot cause damage to any surrounding wiring- it's unlikely though possible that they may become hot enough to melt the insulation off of adjacent wiring if they are in physical contact with it.

I went by radio shack and the only 10ohm resistors they carry in the store are 10ohm-1/4W and 10ohm-10W. I know JGS Tools has them with the heatsinks, 10ohm-50w. I was hoping to find them local.

Didn't know JGS carried them... (searching web...)

I was going to send you a link to the DigiKey catalog, but $19.99 for a set of four is a good price. Buy 'em.
