Your best bet is to build your own! Most kits have to be hacked up to make fit nicely! Buy the wire and cut to length place them all together and start attaching the ends to proper location! This is the best way and only takes a few hours with a few breaks along the way! There is also a wiring code for marine colored wires! I will see if I can find it!I need a wiring harness for my 19' eliminator. Cp performance has one for msd, does anyone know how long of a boat its for?
