I read the howto's, but it seems i have 4 clips from 2 different cars (so the 'common' colors aren't 'common' anymore ;p). It's like this:



Where should i put the resistors?

 

Typically there is a heavier gauge wire on the DSM injectors. This heavier wire is what gets hooked up to the power wire on your stock harness, which is the yellow wire with a black stripe.

 

On the injector side, it doesnt matter which is which - either one could be the constant +12 volts or the ground. I put the resistors on the powered side but I think you could do it either way just as well.

Or much much better yet set up a PWM circuit for peak-and-hold.
