When I got my OKR converter I looked at the pin spacing and noticed it would not fit into the holes of a circuit board from madvapes that I ordered; the spacing of the pins on the converter were too close together. So I started looking fro another way to connect the converter to my wires. I got online and searched Mouser's site for a connection adapter. I couldn't find one so I called up Mousers and a Tech told me that there was a 5 pin female connector that plugs into the converter. He is going to call Murata and get me a quote for the part. The insert force is high enough that a really good connection is guaranteed. It is a part that Murata makes for the 3 amp, 6amp, and 10 amp converter pins; the pins are spaced the same on all three models. When I get the quote I will follow up on this thread with the part number for anyone else interested.
