Product Questions
Is this the version with the removeable cable? Many thanks.
Question by: Paul
Yes, the controller uses a removable cable.
Answer by: Front Runner
Other than making an extension, is there any way to order a longer cable only or connect two together? I need a longer cable for my display. Thanks.
Question by: Wade Holguin
We checked with the manufacture and they do not have any type of extension of this item. Modification would be required to extend this items plug.
Answer by: Front Runner
Can this controller be used with deep cycle gel batteries such as the yellow Optima battery?
