In regards to the 25, I'm not 100% sure on that, never was too sure, you'd have to check up on it yourself. But as mentioned before, and as shown in the pic, it does come with the loom. You'd need to re-tune it regardless of what motor/setup you are running it on.
As for Auto RB20, same deal. I'm not a tuner, I'm just selling what I had one my car .
