Connecting wires between modules

Anderson  powerpoles,  hands down the best going.  Asexual, 12 colors, any connection configuration.  Best website is Powerwerx.com.  Been using them for 15 years.  I always keep a nice assortment.  Buy their crimper.  excellent investment.

This is the default standard in Ham Radio circles.  Ham Radio stocks them in their stores.

I use their 15,30,45 amp housing.  That is a one size designation.  Three different crimp  on ends for which ever wire size you are using.

Powerworx will sell you an exact size/color  count on any order.  great product, great vendor.

The photo below is a wired lift out with power supplied to the last 3' of each R.O.W, on each side of bridge.

Note male dummy plugs on each end.  just to provide a larger body for my ham size fists.

Magnets to hold the lift out in place.  Brass dowels to index set the bridge.
