DRL's and Heavy duty headlight harness

I have the LMC harness and have no issues.
Yes it does improve the lighting, because the lights get full voltage from the battery. Also the headlight switch does not have to carry the load of the lights.
I have a similar setup on my 65 Mustang and it made a huge difference on that application. It is noticable on the F150.
Just get rid of the DRLs. I hate them. They are annoying. They also sometimes make it difficult to see the front turn signal during the day when the sun is in certain positions.

Thanks very much. I don't think I understand most of that but electrical is not a strength of mine. If you're willing, an diagram would be great.
What I'm really hoping is that I could isolate the circuit in the original harness that controls the drl and hook it back up. Unless someone has already told me that isn't possible and I'm just not getting it.

After allot of though into this mod and looking at the headlight and day time running light wiring diagram this should work... but I'm no expert and there is no info on how exactly the DRL module works so I've made some assumptions on how the module operates in regards to its turning off when the headlights are turned on. But looking at the diagrams it's clear that the DRL module is spliced into the high and low curcuit of the headlights so it must get something from those splices other than the ability to power the high beams.

A fix to keep the LMC kit would be to get another relay for the DRL
The DRL relay's coil would need to be powered by the DRL feed, and acutated through the other relay(s) NC contact(s). IF they got spare NC contacts. that is.
once any one of the other relays are energized the contact would open and cut the power to your DRL
I'm assuming that this LMC kit has 2 relays, one for high, one for low?
