Trouble shooting the headlights on my ‘99 K2500. While testing at one of the relays in the All 4 on Hi harness, the cover on the relay simply broke apart. Testing revealed other issues and there was plenty of corrosion. So it’s time to replace the All 4 on Hi harness and I can’t remember the correct one. Is this the correct harness (note: the check fit function does not work):
