Redline Lumtronix Headlight Power Upgrade Harness For Two Headlights 1965-1973 is rated 4.9 out of 5 by 12.
Rated 5 out of 5 by from Definitely made my lights brighter! So everyone knows you would better off driving with a flashlight than with stock wiring and bulbs. I bought this kit just to give it a shot and wow! The set up was as easy as could be and definitely made the lights brighter. I have sealed beam Silverstars in my car right now (plan on upgrading to the H4 bulbs) and it works great on them. I have my '68 stored for the winter so I haven't been able to see the improvements on the road but it lit my garage up with the lights off. Definitely worth putting this on your car for safety and looks, and it's less wear and tear on your old wiring.

Rated 4 out of 5 by from Awesome mod and great product I bought this because I was getting that "blink of death" on my 64 1/2 mustang which this product totally eliminated which was awesome but the install on the 64 1/2 is a little different than the 67 in the video. I gave it 4 stars because wiring it for the 64 was a little more of a pain and the cable that connects to the positive terminal was too small. One other small complaint was it didn't come with any hardware for the grounds

Rated 5 out of 5 by from Very Impressed This was definitely a worthy purchase. Since the upgraded Halogen LED's these are made fore require more current than the normal factory bulbs, there isn't really much that can be said. The wiring is great quality, no shorts or opens in the circuit that needed to be fixed from the factory, nothing really difficult was required in this. Just works as advertised.

Rated 5 out of 5 by from Really Helps I was a leary about this product. My headlights were not flickering but they also were not bright. I had the LED outlined Halogen lights on my 66 Coupe. This wiring harness has improved the brightness of the lights significantly. If you are having problems with dim headlights, this is an easy fix taking just 30 minutes to install.

Rated 5 out of 5 by from Easy to figure out. Watch the video first! I installed my harness a couple of weeks ago and it was fairly easy. The lights work great now and it was clean and easy. My only problem was figuring out where to mount the relays, but I mounted them up by the battery. The really only difficult part was fishing the wires into the headlight bucket, but I got it done!

Rated 5 out of 5 by from Great harness I bought this over a month ago and it came in just as advertised and was easy to install. Fixed my flashing headlights issue and I recommend this harness to anyone who is having issues with headlight flashing

Rated 5 out of 5 by from Great Quality, Easy Install This was a great upgrade and an easy install. I did this at the same time I shopped to HID lights. The light sockets are ceramic so no worries of overheating and melting the connections.

Rated 5 out of 5 by from headlight relay harness I am totally happy with this headlight relay harness for my 1966 Mustang. It was very well built and easy to install and works very well with my Sylvania halogen headlights.

Is there enough wire to route the wiring through the radiator support like the existing headlight harness?  What should be done with the original harness driver side headlight connector?

Asked by: 65Rick
I had more than enough wire to tie- wrap new cable to existing cable along top of radiator and into hole at driver,s side headlight. The original driver side headlight connector is not used and is just stuffed back into the headlight housing. It worked very well on my 1966 Mustang coupe. Bill127

where does the connector with the red/white/blue wires plug into?

Into an existing headlight connector, that you unplug a headlight from.

Redline Lumtronix Headlight Power Upgrade Harness For Two Headlights 1965-1973 Video Transcript
By Bill Tumas: As the regular viewers of our YouTube channel are going to know we've shown you a lot of ways to upgrade the factory headlights on your classic Mustang, including the H4 LED's shown here on our '67 Mustang convertible. The H4 bulb is going to be a lot brighter, and a lot safer than the factory halogens, but unfortunately it's going to draw more amperage, which can be an issue with the factory wiring. The factory headlight wiring harness on this car was never designed for that kind of amperage, and it's also over 50 years old, so there may be some issues.

If you've already upgraded to an H4 bulb and have issues with the headlights going out, or are considering this upgrade, we're going to show you how to upgrade the headlight wiring harness on your '65 through '73 Mustang.

This headlight upgrade harness is going to fit your '65 through '73 Mustang with the exception of the '69, but there is a '69 version available as well. Basically what this does, it replaces your headlight wiring, uses the factory wiring only as a trigger. The trigger will come off the factory plug here, which goes to a pair of relays. These new ceramic tip ends will go to your headlight bulbs themselves. It has a zone dedicated 12V power source, as well as ground, so it puts less stress on your factory wiring, giving you much more power to your bulbs.

For this installation you need a Phillip's head screwdriver, 3/8 ratchet, 1/2" deep socket, 1/2" wrench, drill, small pilot drill bit, and safety glasses.

You'll want to start the installation by pulling up both of your headlights. The process is pretty much the same for most of the years. You're going to pull off the ring, and there's a retainer underneath it.

Our H4's already have this adapter, which we're going to want to remove, and get back down to the original wiring harness. Overall the connections for the headlight wiring harness are going to be pretty simple. There's only four connections on the passenger side, and then two simple ones on the drivers side. The passenger side, this here is going to actually go to our headlight. This is going to plug into the original headlight plug, this little good ground, and that's going to go to a 12V store battery.

What you want to do is pretty much fish the harness up from the bottom. This can be attached to your factory plug, but if you've done so underneath you'll have to stuff everything back into the headlight bowl. The only thing really coming in the bowl should be this plug here, and then an RK is going to be a separate wire here with the four LED plug. We're going to plug in our headlight again, just to make sure we don't pull it down while we're pulling the wires through. You don't need to mount it yet, just leave it sitting there.

We're going to move up top now, and disconnect our battery before we start fishing our wires up. In my case now I'm actually going to take off the bracket, or loosen the brackets and battery, so I can slide it back, because I want to fish the wires up through the front. These are the three things I've fished up through the side here from the headlight bucket. I'm going to put them through this opening, put them up in behind the battery. This is where the two relays go, and this is our 12V connection.

I'm going to mount the two relays here, including the kit down here, but I actually want to hide them a little bit further down on the bottom. I'm going to pull the battery so we have more room. I'm going to mount the relays down here to hide them, so we drilled two small holes to mount them. The relays mounted, now we can reinstall the battery. Make sure you have your positive fished up towards the positive terminal, and reinstall the mounts.

We're going to scrape a small section behind the headlight bucket here down to bare metal, so we get a good ground. There is no defined spot for this ground, so wherever you can get a good bare metal ground, just go with that. Now we're going to fish the harness over to the driver's side. You want to stay towards the bottom of the radiator supports, and make sure you have enough wire to get it over there. Once all the wires are run, the grounds are done, we're going to plug everything in. You don't want to mount them yet, but plug them all in. You want to put 12-volts to them and make sure everything works.

Once everything's connected you want to install the fuse to the power wire; now let's try our lights. We're going to make sure everything works, turns on like it should. Now we can go back, hide our wires, reinstall your headlights, and your installations finished. I'm not sure the camera's going to pick it up, but in person, the headlights on our '67 are noticeably brighter after installing our new headlight wiring harness. If you install the harness with aftermarket headlights and still have an issue, make sure you check the headlight switch, because that could also cause an on/off problem.

As far as installation, figure an hour or two depending on how particular you are about hiding your wires, and you'll be back on the road in no time.
