Hello,
I too am looking for an answer to this question. I recently purchased a set of Bowens, Traveller, Linear heads, which were reportedly converted to Speedotron from Bowens. However, upon receiving the units and testing them with Speedo packs, they blew my circuit breakers. I tracked down the original owner and turns out, per my suspicions, they were actually intended to be used with Norman packs. So, I'm also looking to rewire the plugs from Norman to Speedotron. Should be very simple to re solder the pins in the connecter. Any direction would be very much appreciated.
