I did a search but cannot locate anything that tells me the fuse if any for the cigarette lighter? I purchased from WH a USB chargerhttps://www.wildhorses4x4.com/product/2-Port-USB-Socket/Dsh_switch_PartsL I opened up the hole from the cigarette lighter to accommodate it. Thinking I can use the power from the cigarette lighter to power it. I opened the hole up last night, mounted and wired it and after all done I had no power! %) Help!
