For some reason Silverleaf has hidden the price on their website. It makes no sense to me, but I experienced the same thing when I was buying a new one last month. Call silverleaf, they have a plug specific for the rectangular plug that Newell chose to use, but that plug is not what normally comes in the kit.

I went the easy route, and used the rectangular plug, then simply unscrewed the port from it's location in under the dash above the accelerator and moved it under the dash so the cord wouldn't show.
