HID Firing Problem

ok here is a wire diagram of how i have my lights wired. i wanted the kc's to work when i flipped on my brights since i didnt get the hi/lo kit from ddm. so i originally had just the high beam wire from the stock headlight plug used as the switched trigger wire for the kc relay. but i found out that when you pull the hi beam flasher towards you the highs come on and the lows stay on but when you let go it went back to just lows. but when you flipped the lever away from you where it will stay it kills the low beams and lights just the high beams. thus i had ks's only and no hid's when it was flipped away from me. so if i wanted both on i had to hold the lever towards me. so today i used the high beam wire to trigger another relay that sends power to the low beam wire on the stock headlight plug so they would still get power when i flipped the lever to high beam. so now when i flash the lights with the headlights off both the kc's and the hids come on. and when i have the headlights on and pull the lever towards me it turns the kc's on and the lows keep their constant power. now the problem im having is when i push the lever away from me. it does power the hids and the kc's like i wanted it to so i dont have to hold the lever towards me to have both on, but sometimes one of both of the hids shut off when i do that. i believe it is because when i flip it away from me the stock lo beam power shuts off and then the high beam triggered relay kicks in and the hids shut off for a fraction of a second and then turn back on again as the relay powers them rather than the stock wiring. so sometimes it works flawlessly and all 4 lights are on, other times one of the hids doesnt come back on, sometimes neither hids come back on. now to get them to come back on again i have to turn the headlight switch off and back on again. also if i put the lever in the high beam position and turn the lights on, both the hids and the kc's turn on fine. but if i got back to jsut lows and then switch it back to the high position the lights flash as the power source is switched and sometimes they dont come back on right. i could just turn the lights off and back on again every time i switch it to high beam so that all 4 lights work right....but id rather just have it work right all the time. also i tested power at one of the headlights when they wernt working and there was power, its just that the ballast wasnt firing. i unpluged the wires from the balast that come from the stock headlight plug, and hooked it back up and then it came on right. so is it something wrong with the balasts? or is just the fraction of a second power switch just too much for the ballasts? also i only ran the power wire to one of the stock headlight low beam wires. i guess it back fed through out the harness and powered the other side to. is that bad? thanks and sorry in advanced for the long post. also the square with High, Gn, and low on it is the stock headlight plug.

how about this.... idk much about hids and such but i thought of this.. what if you connect your high and low beem wire together, at that things the is just before the ballast, then go through the ballast. idk if the hids will see more power or just like an aux setting. if you leave everyhting else the same the hids should operate at the single brightness they have but off the high setting also turning on the kc's... let me know if that makes since

ya it does and that was the first thing i thought of....but since the kc's relay gets the signal from the high beam wire...if you connect them the power will back feed up the high beam wire and trigger the relay even when you have it on low beam...so in order to overcome this you would have to put in a diode (which i believe only lets power travel through in one direction) thus solving the trigger problem when on low beam....but i have heard that diode's are expensive...and i had a relay laying around so i decided to do it that way...not sure if the diode way would be better or not...
