HKS EVC… does anyone have this installed?

I just acquired an HKS EVC that was never used. I think it’s the original EVC because it only has a High, Low, and Manual setting. On the back, there are two pots to adjust High and Low settings.

My questions are… does anyone have a manual for this unit? If so, could you scan it and e-mail me a copy?

On the Electronic Valve there are three ports. The port on the left is the smallest and I think connects to a vacuum line. The center and right ports are the same size and I believe they should connect to the intercooler and wastegate. Which one goes to the Intercooler and which one attaches to the Wastegate?

What size and grade of hose should I use for these connections?

How do you set the high and low pots on the back on the cockpit control unit?

Thanks for you help in advance.
