We are installing Holley RetroBright High performance LED headlights. Can anyone recommend a good video or pictures of the installation other than what's in the manual. Any information would be appreciated.
Thanks
Just found an excellent video by Banging Gears

What information are you looking for specifically. Holley's site says these are plug and play. If they are anything like the amazon ones I got you install them the same as standard headlights. Maybe with a plug adapter. Are you using the RF Harness, some other brand, wiring yourself? I wired the RF harness to a weather tech. Then wired the weather tech to pigtail that came with the headlights. I used the RF manual and the little wiring card that come with the lights to figure out which wires to which wires. Hi/lows work fine so far. here is the old bad photo I have of the wiring.

On other thing I will point out. I did end up de-pinning the weather tech to put the pigtail through the headlight bucket. So you probably want to do that for initial wiring.
