| | Re: Best Method to Splice One Wire into Another
There are no marine three way connectors that I know of unless you want to use a stud & have each wire connectected to it by a ring terminal.
However, an easy way to insert a wire into another is to cut the receptor wire, trim the end of the new wire & one end of the receptor to expose the actual copper, then insert them into one end of a suitable size heat shrink butt connector (probably blue for two pieces of 18 ga). Now crimp them. You are left with a single wire that will not fit snugly into the other end of the butt connector as it is too small. Cut another short piece of 18 ga, strip it & the other piece of the receptor wire, slide the appropriate size heat shrink tube on, insert the short wire & the receptor wire into the butt connector, crimp & then heat to set the glue. Slide the heat shrink tube over the joint, heat & it is done.
