Review of Spectro Accessories and Parts 38656

Today we are going to review part number 38656. This is the Spectro trailer wiring junction box. This junction box will help provide a fast and easy way to connect your wires from the trailer connector to your trailer wiring. It does make replacing the trailer connector very simple. This part is constructed of a heavy duty plastic. It is weatherproof and corrosion resistant.

I am just going to open it up to show you what it looks like. I have got the two screws already loosened. If we move that and take off the lid you can see the junctions on the inside. The lid has a nice groove right here that when you set it down onto the box and then tighten the bolts down it would give you a nice weatherproof seal. On the inside of the box, you can see there, in raised letters on each post at the top is the color of the wire and then on the bottom is also labeled the function.

It shows you the seven post. This is designed for a seven-way or a six-way trailer connector. I also want to show you the way to run the wire into the box. Right now it just has the rubber plugs in it. It does come with five extra rubber plugs with the holes already in them for the wire to go through.

It comes with the clamps to clamp the wire down and also the other installation hardware. Basically on this end you can see there is one plug. On this end there is two plugs and on each side is one plug. There is a total of five, so you can replace all five if you want. If you are not going to use this opening, if you want the wire coming out of there you can just put that one in there.

As you can see it gives you the opening. If you do not want to use this one then you can just leave the plugged one in there to seal it. I just want to give you a few dimensions on this. We will put the lid back on lets get it right on there correctly, there we go. The overall length on this box is seven inches. The overall width is going to be three and a half inches. The overall height with the lid on is two and a quarter inches. Also, just to give you the overall width with the mounting flanges as you can see on each end here, they have a quarter inch thick mounting flange so when this is mounted to your trailer it will hold up really well. The overall with those flanges included is going to be eight inches, and the distance from the mounting holes center to center of those flanges is seven and three-eighths inches. I will show you again how it opens, and you see the post in there. That should do it for review on part number 38656.
