A must have for aftermarket lighting.
A must have for older rigs converting to LED lights. This is a super affordable way to take the load off of your factory switch and get a dedicated 12v to your headlights. Converted my 1990 Chevy 3500 to LED and I tested with and without. First test, no harness: when the blinkers were on the headlight would flash quickly and they seemed slightly dim. Second test, WITH harness: full brightness, no flashing with turn signals, super clear. Such a simple solution!

Determine what side the control lamp is by unplugging each one until both go out.
Great product! Installed with Uni-Shine 7" LED headlights. Only issue was that on 87' Suzuki Samurai the headlights are designed with a control and slave lamp design, the control lamp can be on either side. Mine was on the driver's side and the positive wire was too short to reach the battery on the passenger side, easy fix. Harness installs easy and blends in well with original wiring harness.

Still Ground the Old Sockets
Definately plug & play. I've wanted to do this conversion for years. AMC did many great things in building the Jeep, but the lectrical system & using the body & frame for ground was not one of them. This harness worked great for a bench test. Then not after I installed it. After more than an hour of testing EVERYTHING, I realized that the ground wire from the old headlight socket still needed to be grounded. Once done, we had lights. Thanks for this si.ple, but effective upgrade.

Works great!
Worked great on my 94 xj cherokee. Ran the wiring alongside the coolant reservoir hose, grounds to one bolt on each side of the upper radiator support and mounted the relays on the inner fender by the battery. I had more than enough slack

Direct fit in my 2000 Cherokee XJ - There is no need to cut and paste anything.
Plug & play mod for H4 headlights, it has increased brightness and flash response time by a big margin. It's a one-time investment to tune up poor headlights. Make sure you place the relays in a good place away from direct heat.
