Colis reçu, l’annonce est porté à confusion voire même être frauduleuse puisqu’elle indique 106.7m total de fils, en fait c'est la longueur total de tout les fils et ce n’est pas des MÈTRES mais bien des PIEDS.106.7m est égal à 347 pieds je n’ai reçu que 34.5 pieds de longueur totale. Veuillez change votre annonce pour des pieds et non des mètres.

After having to replace my boat lights several times, I FINALLY HAVE REALIZED THAT I NEEDED A QUALITY ELECTRIC CABLE HARNESS. This is a real good one.

I purchased a boat trailer and the wiring was fried literally black on the inside from poor connections and too many splices. I ordered this and it was shipped extremely fast and the thickness of the insulation was a great sign this product will outperform the previous wiring greatly. The length was great as it gave me plenty of extra for the 28’ trailer with wiring looms going along. This was such a great value for the length and quality, and performance. It was very easy to install only taking half an hour or so to get it wired in.

Liked the gauge of the wiring for my 16’ utility trailer. Disliked the smallish eye terminal on the grounding wire…I had to replace with a more useable size.

Definitely get the wishbone style, this will save you time when wiring in side markers. I used the 35' length to wire a car trailer with 20' deck. Definitely get longer than you think you'll need.
