    Here is a wiring harness I bought on amazon, came direct from china, but the quality appeared very good.

    http://www.amazon.com/dp/B00H5JFHR0/ref=sr_ph?ie=UTF8&qid=1420144346&sr=1&keywords=relay+wiring+harness

    It was just long enough for my 65 (no extra) and the nice thing was that it has a plug to tie into the old harness without any cutting/splicing and even the battery power cable all seemed cut to the right length.

    Separate fuses for high/low so you shouldn't lose both beams at once and ground straps hanging from each headlight socket.  Overall was pretty happy with it.

    The only negative was the sockets exit out the back instead of the sides like the oem style .. there is not much room behind the headlights so the wires were a little tight.

    That's an insane deal.  I was gonna build my own harness using head Light connector ends and other impossible to sourc factory ends.  But for that price I dunno if I could buy everything I would need cheaper.  There use to be a place online that sold pretty much any wiring connector known to man available.  I can't find it anymore they must have went under to bad it was a U.S.  company to.

    I built a new harness, it's not hard and we'll worth the effort.  I am planning on doing the same harness on the convertible.

    65 coupe, 351w, c4, power disk brakes, power r&p, vintage air.

    Why are you doing this? Is it because of the amperage draw? Wouldn't LED's be better? Just askin.

    This takes voltage directly from the battery and supplies it through the relays to make the headlights brighter, bypassing the headlight switch for power.  It makes a noticeable improvement in lighting without having to buy new bulbs.
