Converter Box for Separating Out Combined Trailer Wiring Circuits

Question

Question:

Product Recommendation. Is there a way to convert the flat 4 left/brake and right/brake into separate leads? Im not towing a car, just connecting lights. Would it be better to replace my car connector with a 7 conductor round for the separate connections? Thank you,

We do have converters that are designed to take a combined stop/turn signal circuit and separate them out with the converter part # 118158. You'd wire the combined circuits to the input side of the box and on the output side you'd have separate circuits. You'd need more than 4-way wiring though. We have a 5-way with a 60 inch lead with the part # C58531. Then for a matching connector for other side you'd want the part # HM37918.
