I have SARD Power Band but all the instructions are in Japanese, does anyone know what each wire does in a colour format? I am fitting this on my 2003 Nissan 350z Jap Import - would like to know the fittings for the ECU as well???

Your help would be appreciated!!

 

What exactly is this "powerband?" I've heard people say, "I just put a powerband on my bike." And that is complete BS. At my old job, we actually put a label on a box and told a guy he could buy a new powerband and he was about to buy the thing. I guess you're talking about the powerband indicator?

IMO, I'd just call it a shift light. Do a search for shift light installs.

If you have to, call or e-mail the company. I'm sure they can send you some instructions or have tech support.
