Splicing Wiring for Navigation Lamp Circuit

I bought a replacement navigation lamp pole from West Marine to replace the broken one on my 2001 Outrage. It mounts on the front of the grab rail just above the acrylic windshield.
Where is the best place is to splice the three wires? I am replacing the original, so as far as I can see, no splice currently exists. My electrical skills are quite limited, appreciate any advice.

Can you pull the wire out some to work on them? And then are you able to pull the wires back into the console? You will need some heat shrink, silicon, and a solder iron. The correct way to splice the 3 wires is not to do them (cut them) in the same place, because then you create a large bundle of wires. Space the cuts about 2 inches apart down the line, twist the wires, slide heat shrink over each wire, twist the wires together so they lay flat in line, solder the wires then slide the heat shrink over the connection and heat it up to make a seal. I would then coat the heat shrink with some silicone to make a water tight seal. After the silicon dries pull the wires back into the console...good luck

I am not clear if you are replacing just the steel tubing for the lamp fixture or if you are replacing the entire assembly of tubing and lamp.
Is there a connector on the original lamp post assembly that mates with a matching connector on the boat?

In general I recommend avoiding making a splice in an electrical conductor on a small boat. The cost of running a new conductor without splices is not prohibitive, and installing a new, one-piece conductor should be the first option when faced with repair or replacement of an existing circuit which has become interrupted.

Splices will be necessary because the new light has short
leads. They are no problem if done right.
I'm guessing that the existing wiring runs through the grab
A. If it's a salt-water boat, the wire may well have wire
C. You know it's done right.
Here's what I'd do:
Find a buddy who can help you with #3 and #5.
1. Use the existing wiring to pull a strong cord through the
2. Go down to West Marine or other chandler and get a piece
4. Use the cord to pull the new wire from the console to

I am still not clear about the replacement navigation lamp fixture and its wiring. Was there a connector in the original configuration between the boat or console and the lamp pole? Or is the lamp pole permanent wired into the console?
If there is no connector and you must splice into the lamp circuit to install the new lamp fixture, I would try to conceal the splice inside the steel tubing. You may have to disassemble the lamp from the tubing so you can make the splice and then stuff it down into the tubing.
I like to use two layers of heat shrink tubing over the splice. This builds up the insulation around the splice. You don't need the insulation for electrical reasons, as 12-volts DC can be insulated by a few thousandths of an inch of insulation, but the extra thickness of insulation will make the splice more durable and less prone to being nicked or cut.
