I bought a Painless kit then stored it for 4-5 years before I installed it. It wasn't painless by any means, but that could be more on me for the changes I made. It did go together well.
Cons
The headlight and ignition switch they supplied were junk.
I had to make every end point termination, but I guess that would be the case with anything other than a factory replacement.
I had to add relays for the head lights.
I would have been nice if painless would have included connectors in all places that Ford had them, like the firewall plugs and front running lights. I soldiered and heat shrinked the connections I made.
I didn't like the 70A blade fuse they sent for a main. Used Bullet Bob's reference guide for wiring to purchase better stuff.
Pros
The wire was long enough to route any way I saw fit.
The wire colors matched what Ford used on a 67 model, which I thought was good.
Mine came with a relay for the horn built in.
There was (1) 20 amp circuit that I could use for what ever. Can't remember what I used it for.... thinking I saved it for fog lights. The power window kit I bought needed more than 20 amps if I recall.
I liked that it was new wire and better insulation than Ford had available.
The instruction manual was very good. If you go with Painless, make sure to keep whatever instruction manual they send. When they make updates to a harness, the most recent version of the manual is all that remains on the website.
The customer support was good as well. I have a factory tach car and the instrument cluster wiring they offer does not have provisions for the tach and idiot lights. I drew up something that I thought would work and walked through it with them and they agreed that I was in good shape.
Painless offers a sleeving material to cover wire. It works great, but can be sourced a lot cheaper from other places.
I added a 3G alternator, dura-spark ignition, power windows, power seat, USB charging port and had to figure all of those out as well.
