This this increases voltage to the headlights by bypassing the stock headlight switch and routing power from the battery right to the headlights. resulting in brighter headlights. Has anyone done this? Information?

All work done at front of the car near the lamps. I did a 69 Barracuda for a customer, but we replaced the intire harness with an EZ brand harness. And that was about 4 years ago so my memory has faded. Brad Check out the Dorn's 69 Barracuda "Switchblade" in the Nov.2010 MCG Check out the Dorn's refurbished 36 Ford in the Feb.2011 Street Rodder

Worse place you could choose as the power source. Tap off the alternator output stud. They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

I have done this a dozen times or more. https://www.youtube.com/watch?v=Tw9QkkT2ptU http://www.lindamaki.com/wp-content/uplo...ing-diagram.bmp The relays are available at all auto parts stores. Use the one that is pictured in the video above because it has the mounting tab made on it. You do not use the middle spade, only the 4 outside ones. The starter relay is the power source that I use due to it's convenient location. There are other videos on UTube if you need more reference material. And I think there are other threads here on Moparts on this subject with even more info. If you have anymore questions, just ask. Master, again and still

I think he has a listing on Moparts, but here is his listing on A bodies only. http://www.forabodiesonly.com/mopar/threads/plug-and-play-headlight-relay-kits.216514/

Agreed, feeds em right from the (power) source/increases brightness from less voltage drop (which is your intended purpose)/takes load off of the bulkhead/keeps the ammeter honest. as said trigger em with the hi/lo beam wires live every 24 hour block of time like it's your last day on earth
