I don't think they have a tech line, but they responded to my emails very quick. Just email them what you have and want any they will hook you up. They sent me the bulk head to convert my bucket to the bigger 4 flat connector, a longer pigtail for the fuel pump so I didn't have a splice in the tank and a plug an play harness that plugged into my stock square wire plug and then into the bigger 4 flat bulk head on the bucket. It was very easy to install and all plug and play with bigger stuff. I think they even put together a kit will all that stuff in it.
