Icon3 How to rewire my DLR for new headlights

TLDR i want to rewire my daytime running lights to only go to my new halo rings and wire my lights so both lights come on in high beams instead of switching the projector low beams off and turning on the reflector style high beams
So recently i bought the spec-d projector one piece headlights and with them comes a halo/led pod for Daytime running lights, as im in Canada its required, but ive noticed when the DLR is on the halos are super dull and it turns the high beams on low too, only going to full bright when I've properly put my high beams on, so i was wondering if anyone knows how i could rewire it so only the halos/led's get the power rather then the high beams when the DLR is on, another issue i have is with these headlights splitting the OEM style single bulbs into a dedicated high and low headlight, when i put the high beams on it turns off the low so i was also going to see if there was a way to keep the low on when i flip to highs, one

I had those headlights. The LED halo's are super weak and I was going to attempt putting my own halo in to make up for it but sold the car before I did.

The day time running lights (DLR) are only on when the head lights are not. There is a separate control box in the left kick panel that kicks them on under specific circumstances and cuts that circuit out in others. One part that may or may not help you is, the DLR runs through a resistor box to reduce current to the headlights as they are normally halogens. Lower current with same voltage means the low beam element doesn't burn as hot aka lower light output. If you bypass the resistor box, the full normal low beam current goes to the bulbs. With LED that probably won't affect it much as I noticed with my LED bulbs, the resistor didn't drop the LED output hardly at all.

The basic layout of the system is you have two hot wires to the bulb, high and low with a single ground. There is circuitry between the battery and head light switch on the steering column that either puts out full current or partial current on the low hot wire. You would need to do a lot of work to bypass the DLR circuitry beyond just DLR resistor box.

Thinking about it a bit I think you could run your DLR as separate wiring to the reflector lights and the LED/Halo and then your regular low and high to projectors. Or you could run your DLR separate to the reflectors, AUX power to the LED/Halo and the regular low/hi to the projectors.

Later today I will take a picture of the DLR ETM page for you so you can see the circuit.

so im wondering if i bypass the DLR box then take the hot wire for DLR and remove it from the main bulb connector and just run it to the halos if its take that, its got in line resistors on the headlight harness and when its on high it doesn't fuss so ill make some jumpers and see how it will take to that. the second thing im still trying to workout in my head is trying to get it to keep all 4 lights on when i switch to high. It would be real nice to have both projectors and reflectors on when i click it into high rather then solo reflectors, ive noticed if I hold the high beam switch to just before it "clicks" to switch on high, it will run all 4 lights. but once its actually switched into high the projectors go out, more then likely would probably have to do some bypass in the column switch itself no?
