Wiring Help

Ok...how does a novice electrician hook up the two single NMEA wires from my Garmin chartplotter to the Icom 504 VHF wiring? The confusion is with the negative outer shield and the inner positive?

You have to strip the outer insulation to expose the shield wires. Both shield wires have to be connected to a commpn ground. Here's two pictures of my install.

That's what I thought. Thanks for the photo. Where did you get that plastic buss?

The euro style terminal strips like Tom used from radio shack can be difficult because there is only the diameter of a screw inside the hole to actually hold onto the wire. Blue Sea used to sell some that had a flat plat inside making it next to impossible to get a bad connection but they no longer have them. I find myself using the one Tom used often enough, however, you might also consider a regular style terminal strip linked here with spade connectors for a more robust connection - http://bluesea.com/category/9/36/products/2408

Jim, and others looking for a good quality terminal;

Try these terminal strips. They have the protective metal barrier plate inside, and the screws cannot fall out when loosened. Inexpensive, too

Nice find, probably the same ones Blue Sea would sell. I bookmarked that page.
