Curious, why not build your own?
Hi Mark, how are you? This is my opinion answer.
'Why build your own? It's more work, Have to buy wire, can't get all the colors easily. Have to buy connector shells, have to buy contacts for the connector shells, have to buy terminals, have to buy, and wire, a fuse panel. Have to buy boots, switches, flasher, fuses.....Wires have no markings every 6 inches. Terminals, packard 56 shells and contacts have min quantities at some vendors. No returns, no instructions, no free shipping and same price or more. No advantage whatsoever.
Been there, done both. Buying one is the way to go.
