13.1 volts at idle seems pretty good- have somebody get in car and raise RPMs to typical highway speed and see where that voltage number goes, if it gets much higher than 13.4-13.6 I would NOT add a harness, as you will be replacing bulbs much more frequently than needed.

EXACTLY why I recommended the above!

As an aside, the MkIV Jetta/Bora H4 headlight, Ecode, is known to be pretty ordinary. High quality bulbs will help but they are still not very good. Then again, VW H4 headlights have never been very good.
