Green wires that go from the switchbox to the ignition coils (one wire to each cylinder, etc.). 1983 150 V-6 Merc. Mine are crumbling and I accidentally bumped one yesterday and it pretty much schreded. I want to build new ones rather than buy and wait for delivery. Is this a stupid idea? What's the worst thing that could happen? What type of wire is this and where can I find some? Thanks in advance for your help!!
