LMC Heavy Duty Headlight Harness Problems

I tried and tried to figure this problem out on my own going on 2 weeks now. I've done some researching online and on this site and have finally windled down to nothing... as in, I'm out of ideas of what's causing my problem.

Short story long, I purchased the 4 square type euro lights with push-in style bulbs and the recommended harness to go with it. Needless to say the instructions might as well not even be printed on the back because it was lacking lots of instructions and whoever wrote the English must have flunked English Grammar 101 over there in Taiwan. Anyway... I wired everything up the only way that made sense to me and the only real questionable thing is where I plugged the harness into the existing low beam headlight harness on the passenger side. The other is where each harness was plugged into the headlights.

OK here's the problem. The first time I turned the headlights on the bottom lights (high beams) turned on and then when I clicked the high beams on the top lights came on leaving all 4 lights on. I figured this was wrong being that the top lights are the low beams. So I switch the plugs around on the headlights. That corrected it but for a while there sometimes it would work and sometimes the low beams wouldn't come on at all just the high beams. I end up running out of patience.

The next day after being fed up with it the day before, I tried it again and now the low beams were not coming on plus the parking lights were flickering and I traced the clicking noise (flickering) all the way to the headlight switch. So I bought a new headlight switch. Tried it, no low beams, still flickering, turn high beams on, they come on & flickering stops. Got fed up again.

Next day I open the door, turn the headlights on (low beams) to check and to my surprise they come on after doing nothing. I stand back puzzeled. Low beams work, high beams work & no flickering. Yay! But that was short lived. I go to crank the motor and everything trips (I have a circuit breaker for my main power). Now I'm really puzzeled. I reset the breaker, try to start the motor and it trips again. I reset it once again but this time unplugged the power to the headlight harness. Motor cranks right up. So... looks like I have multi-problems. And I'm out of ideas. Anyone?
