IMHO, the nicest way is the pure stock way, like henry did it. You can get all the original looms and rubber new thru a tbird or fairlane supplier. OR scrounge it off of ebay or salvage. Here's mine, not pure stock but close enough, needs one more bracket, but close enough for me. I drilled out the rubber blocks to accept the 8mm wire.
When it comes to wire color, Jerry Christiansen and I are on the same page - it should only be black.

I will also add, this is PIA to do, but is worth it, you really don't want your plug wires hanging over the valve covers, we all know that's how those scrub guys do it, no wonder I don't like it.
The 55-56 FORD factory manual shows it very clearly.
