A guy named Dennis Igarashi used to work for Seward. When they closed, he continued selling the harness upgrade kits.
My information is from 2015, he may have retired by now. His phone number was 1-626-374-6422. His email address was digarashi@earthlink.net
I bought it, and returned it. Not worth the money. Take the time and make your own. Direct wire from the panel to the engine, use tinned stranded wire, quality heat shrink terminals, and a good crimper. You won't be sorry.
