Question:

I am having some issues with my boat trailer lights. Its a standard 4 plug and there are two marker lights along with a license plate light and of course the running brake and turn are combined in one unit. Which wire kit should I get from you?

Expert Reply:

The Optronics 25 foot 4 Way Wire Harness # A25W2GWB will be a good option. This will generally have enough length to cover most trailers. I will also recommend adding in a few of the Spectro Self-Stripping Connector with Waterproof Sealant # SWC501746-1. These will make splicing into the # A25W2GWB significantly easier. Especially for your side marker lights.
