Question ACA HID install Need help!

I've been working on installing these ACA HIDs in my 1st Gen Tacoma for 4 days now and I cant get them to trigger on using the light switch.
Right now I'm thinking it must be an issue with the stock toyota H4 plug or something like a diode I'm missing.
I know they work because I can bypass the relays and they fire right up.
does anyone here have experience installing HIDs in an 01-04 Tacoma?

1) I know they work
2) I don't have DRLs
3) I discovered the ballast plugs were reversed

Aside from the obvious, is there some well known issue people have when installing these lights in a tacoma?

After messing with the H4 plug today I was able to get the light switch to trigger the lights on,
but only the low beam, (apparently my H4 low is on the side of the plug instead of the middle)
if I switch on the brights while the low is still connected it shorts out or something.

Another thing I discovered today,
when my lights are on I have no ground continuity at any of the three points of contact on the H4 plug,
is there some kind of anomaly with my truck?

Come on, no one has had this problem?!

did you ever have to tap into a hot wire for power? if so you probably tapped into a wire that is only hot when the low beams are on...just a guess

Here is the diagram of the positive switched wiring harness that came with the ACA's



Can someone help me design a Ground switched wiring harness that will work within ACA's parameters based on this schematic?

I have a larger pic if you PM me

Thanks! -J
