IF you could lay your hands on a NOS wiring harness, it would be worth every penny it costs. It would likely have the correct grommets in the correct place. It would have the correct connectors, etc., etc.
On the other hand, you could try buying connectors from Vintage Connections, buy the wire (correct color/stripe will start to cost), and then you have to source the grommets, cut the wire to the correct length (probably using the old harness as a gauge). After that you'd have to wrap the harness and install it. Even if you outsourced the build, the cost would probably run near the cost of a NOS harness.
As far as a Painless kit, if you'd still need to do modifications to have it mate up to the switches, etc. How much is your time worth to you?
Frankly, I wouldn't mind being able to lay my hands on NOS harnesses for my 260Z so I could rid myself of the modifications attempted by the previous owner(s) and the ravages of time.
