FOR SALE Plug and play - Headlight Relay Kits

Headlight relay kits that are essentially plug and play.

There is a substantial increase in voltage at the headlight, increasing light output performance. Light output degrades exponentially with voltage input reductions. These kits also take headlight amp loads off the fragile bulkhead connector, headlight switch and amp gauge. The only headlight load flowing through the bulkhead is a minimal current required to trigger relays.

The kit includes:
Bosch/Tyco relays (no 1$ chinese relays)
Ceramic headlamp sockets
Fuses/fuse holders
12ga wire from alt to relays
12 or 14 gauge power wire from relays to headlight wiring (no 16-18 gauge wire like factory, except 16ga to trigger relays)
All terminals for hook up to a std 1/4 alt stud and ground locations
Wiring would follow normal wiring harness paths and be covered with black shrink tube for most of the run lengths.

NO CUTTING OF YOUR CURRENT WIRING HARNESS REQUIRED!



Road lamp relay kit is not included in the standard 2 and 4 headlight kits. There is an additional charge for a road lamp relay kit.

The kits I've built have relays mounted on the yoke (front or rear), under the battery tray and inner fender uprights.

Picture of the light output difference from a 71 Cuda. Both pictures are on low beam setting, Left - before, Right - after installation.


Another benefit that most users see is an improvement in dash light and marker light/turn signal brightness.

Some other things to consider.
Unless you buy wire in bulk, you'll have about $40+ before tax in different colored wire packages from a local auto store.

All kits I build are tested prior to shipping.

Kits for a 2 headlight vehicles are $135 + shipping.

Most 4 headlight vehicles are $160 + shipping.

The assembled kits fit nicely in a USPS regional boxes, shipping in the US would be in the $15-20 range. International shipping is available. Kits have been shipped to Canada, Spain, Italy, Germany, Australia, New Zealand and a few other countries. Most all shipping is done via US Postal Service unless other service is requested.

Kits with all products and wire required to build one yourself are $85 for a 2 headlight and $100 for a 4 headlight + shipping.

If you would like some other iteration of a kit, parts only, please PM me.

Thanks to all my customers, I appreciate your patronage!

I installed one of these kits on my '68 Charger. Fit perfectly and worked great!

I'm thinking about this install for one of my winter projects. Not being familiar with the kit, it's mentioned there's 'no cutting of the existing harness required'. I have a new engine harness in two years ago...what's done with the existing headlight wiring? Thanks.

Just received my relay-harness kit from crackedback.All looks first class and very well constructed.Looking forward installing it this winter. Thanks Again Rob.

You have to leave the existing harness in place, but won't use the old headlamp plugs. Just tape them up.

As Joel mentions, you leave it in place and will use the low beam plug closest to the relays as a trigger. The others can be taped and zip tied back against the harness.

It's tough to take the headlight runs out of an existing harness. All the markers and turns are in there too, so best to leave them there. You can always return the car to OEM if the kit was removed. The benefit of not hacking up a perfectly good front harness.

Good arrangement so as to avoid cutting wiring, etc. And you've gotten great feedback on the kit. Will plan to order after I tackle a couple other hassles that've cropped up on my car.

Subscribed for when I hit this part of the build...

Thanks for the purchases.

Have a couple to finish as I ran out of shrink tube... heat gun popped today as well... LOL it's always something.

Hey I would love to know more about this Wiring Kit.

I have a 1970 Satellite and would like to use Hella H4, H1 combo for High/Low and High beam to replace the old sealed beams.
I have read through the thread above and sorry for being a bit challenged
Outside the lights is this wiring all I need to complete the installation?
