I would return everything back to stock and see how things work (or not). If they worked properly before the "upgrade" and work properly again after removing it...
I added a obstacle detection system to my truck. It wouldn't shut up and the red indicator lights that went on the windshield posts were so bright that they almost blinded you. I complained to the seller and they didn't reply. I disconnected the power to the system. Now I have unusable sensors in my rear bumper that fill the holes I had to drill for them. Oh well. Chap

Would some type of resistor or canbus module make your system work?

 

Are lights equipped with Canbus ? I have Colight Y6 mini projectors and they're plug and play with the Canbus modules attached to them.

 

I used Oxilam bulbs for both headlights and foglights in 2002 Sequoia and had no issues. Truly plug and play. I have a side facing garage that with a board fence that is 50 feet from the garage door. With the Sequoia backed into the garage, I marked the upper edges of the beam patterns for both dim and bright before changing to the LEDs and then after install, compared the new beam pattern with the halogen tape marks. No adjustments up or down were required. The bulbs were advertised to throw properly in the housings and they lived up to the claim.

 

You might need a load resistor for your LED bulbs. I forget the reasoning but its something to do with not enough voltage, I think. I got this for my truck when I upgraded to LED. My issue was the high beam indicator would not turn on in the dash when I have the high beams on. It might help.

I ordered three exact ones and connected one on the right headlamp

 

I installed one that was recommended. I ordered and they came in a pair. But only installed on the right headlamp

 

When your ready for a real upgrade, try this
