I have a 2006 EZ loader that the electrical connector came undone and sheared off part of the pins. I still have lights, brake lights, left blinker but my back right blinker is now intermittent. I was looking at installing a junction box to utilize the 7 pin connector, but my 5 flat has 11 wires coming into it. I believe they ran two sets of wires down each side?? How do I connect them to a junction box?? Just stack all the same colored ones on each other??
