I could be wrong but I believe all you have to do is remove the resistor box. I know going the other way all you do is solder the resistor in and it doesn't matter which side of the injector because of how the current works with injectors. I will think about it, but I believe that is the correct way to do it. I am not sure how tough it will be to remove? I've been running around Seattle all day and am worn out so I will try and get back on here tomorrow after I have had more time to think about it when I'm not so tired.
