Issue with 18 sport LED head lights I added back in 2018 to my 2016

I remember almost nothing of the specific's but there was some kit I needed to wire in the new 2018 sport LEDs. Had no trouble till recently. my drivers light is out, running light and headlight. This happened a few months ago but started working again. Can someone help me ID what I need 5 years later.

 

Mine were done with crappy T-type taps that ended up splitting the wires (thanks dad ) and I had to replace the harness. Maybe check wires for damage from the connector?

 

True, I did make the connections and I know my quality is meh.

 

Didn't mean to come off any kinda way. Sorry if I sounded rude. It was ridiculous of him to use those on such a skinny wire

 

No!!!
You're right, I wasn't thinking about 6 year old connection that I made with what I had in my old HVAC service van. More than likely crimp on spades and wire nuts.

 

Hello, probably the Morimoto H4 relay went bad I remember your bought the harness from me a while back (01/24/2018) and was the very first version of my harness and by that time used the Morimoto relay to supply power from battery to the LED headlights.


My recommendation is to unplug the connectors and clean all the metal contacts and inspect for any loose wire or water damage. Same symptoms reported from other members and ended being the Morimoto relay seals that went bad and let water corrode the metal pins.

 

Can I order a new relay from you or a link. Both headlights and running lights out now.

 

All better thanks to @iHacker harness and his Saturday support of this dumb ass. Plan to keep her forever so I replaced the entire harness, and over thought it.
