New brakes are electric. In this case, when the tow vehicle starts to stop, it activates the electric brakes right away and helps slow the tow vehicle down.
Installing the new brakes took a couple visits to the marina. First visit, I got 4 of them on, then the following week, I got the last two on.

I drilled/tapped into the trailer frame to mount a junction box and a breakaway kit. The breakaway kit is a battery that is supposed to activate the brakes to prevent a runaway trailer if it comes off the tow vehicle. I used blue Loctite on the threads mounting both pieces. I used smaller bolts on the breakaway battery box. When I used the tap to cut the threads in the first hole, it snapped. Took a while but I got the broken piece out. I went to the store to get a replacement and finished that hole and made another one, going slower to prevent another break.

This past weeeknd, I did most of the wiring. Used marine grade wire and marine grade connectors with heatshrink. Probably overkill but I'm sure the wires will last a long time. I also replaced the taillights and installed a new 7 pin connector to plug into my truck.

|steel line to fish wires through the frame|
|electrical tape only used to cover the center of the 3-way|
|blue wires for the brakes|
|new taillights from Harbor Frieght. nice bight LEDs|
|junction box wired up. color coded fairly well|
|7 pin connector with plastic cover over the wires.|
|left over supplies|
Wiring job itself probably isn't the greatest but I was able to get it done enough to test out the turn signal/brake lights. I still need to wire in the breakaway kit and adjust the brakes. Otherwise, it's pretty much ready to go.
