Ok on my sled I need to wire in my heated shield cable for my helmet, the cord is like a normal tv RCA cable with a red and black power wire on the other end. my sled does not have an aux power outlet so the only place i can think of to wire it in is with the hand warmers. should be able to just hook it up right??? the only thing i can't figure out is when i test the hand warmer power with my voltmeter on DC power it doesn't read anything, but yet the hand warmers work just fine. any thoughts would be great.
