4 Lo/Hi Mod

[DrummerDude70]

Hello, all! Hope everyone is staying safe. I installed the Painless lo/hi mod a few months ago on my 02 Z71. I don't drive the truck much, but travel in it mostly on vaca. The mod worked fine for a short while, but noticed a little while back, it reverted to the factory setting. I used the Painless version for the quality and ease of installation. Any ideas as to why this happened? I looked at the install, and everything appears to be intact. Not very pleased with this situation. The current headlights are the factory ones, but am planning to add an HID/LED setup soon. TIA...

What is the “painless” version?

Shoot, I keep thinking 4 Hi/ Lo in the transfer case. This is for the headlights.

Did you check the wiring connections?

just stick some kc daylighters on the roof and drive around with those on.

Is the relay bad? You could easily verify that with a multimeter or by simply swapping relays momentarily. Beyond that, make sure all of your connections are good. Does the Painless kit use quick splice/t tap connectors? Sometimes the quick splice ones can wiggle loose if you didn’t get a good bite to begin with

You can always just add a ground from the fuse block, port D4 if my memory serves me right to complete the mod as well since yours is an 02. I would have to verify the actual location, it’s been years since I’ve done this mod to both my trucks. You can also add a relay in the same fashion as the painless kit to keep your fogs on with lows/highs as well
