Wiring new VHF

I am replacing my VHF, but can't how to connect the new wire to the existing one. You can see that I have disconnected the old VHF, but can't figure out how to break appart the wire on the new one. Even after I break appart the new one, I am doubting that it will be able to connect to the existing wire. What do I need to do? Sorry about the poor image quality.

you will need to splice the new connector block to the existing 12 volt leads beyond the old connector. Red to red and black to black. Use Crimp style butt connectors with heat shrink and you should be just fine. If you search the existing wire down, you may find that it terminates at a power block and you could then add the new wires there....

Cut off the modular connector and butt splice the new radio's power wires to the older wires. As KD said, you should use good crimp-type butt splice connectors and cover them with adhesive-lined heat shrink tubing. If you cut the wires and notice that the existing wires are copper-colored, rather than silver in appearance, I would cut the wires away and run new, marine-grade duplex cable for the power to the VHF. Untinned wire can be a serious problem on a boat. It tends to corrode and may become a fire hazard, as a VHF has enough of a current draw to be a problem if the wires are corroded.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
