I'm considering using the blue colored Splice Connector and then completley sealing with an Ancor Adhesive Lined Heat Shrink Tubing? Have any you tried this setup? I need to splice into the wire for the side marker lights. On this forum, members have advised: "Throw away the Splice Connectors that come with the kits".

You mean the 3M connectors that have a slot that cuts through
the insulation that makes contact? Walk directly to the
garbage can. Those things are junk even if the they don't
get wet. And the hot melt heat shrink that's big enough to
cover them won't shrink enough to seal to the wire (not even

What's wrong with those connectors:

- No significant strain relief.
- Major stress wire where the slot contacts (and cuts) the
- Sharp edge on the wire.
- Slot must be precisely size matched to wire size and strand

Here's how to splice it right: .

Chuck is correct, those connectors are crap, I don't think they are even worth the material they are made from. Use a butt connector, crimp the connector, solder the connector, use heat shrink, then coat it with some type of silicon. Unless you physically pull it apart it will pretty much last forever...good luck

Pet peeve of mine. You buy a big-bucks boat with high-quality wiring, but you can't spend any amount of money for decent trailer wiring unless you do ALL of it yourself to marine wiring standards. And even then you can't make your own lights from scratch and you'll have to buy some elcheapo so-called-waterproof lights made of thin plastic on a par with kid's toys.

The boating public is known to pay for quality goods.What is the big issue producing quality trailer electrical parts ? They would sell with no problem.

Hear, hear, what swist said, at least mostly. There are some
decent lights out there. The problem is figuring out which is

You can get very high quality trailers and with high quality lighting systems, but they come with a steep price. I tracked down the manufacturer of the trailers used on commercial Boston Whalers, looking for a quote on getting one for my boat. The price was quite a shock, over $6,000 as I recall. I bet the wiring was probably nicely done.
