9007 to H4 conversion

I bought a used set of bugeye lights to do the koji mod to. I just finished and realized that the lights I bought and did this to use H4 bulbs instead of the 9007's that were stock. I'm not sure if this means they're Canadian or European or what.

Can anybody send me to a link for a conversion harness, or a wiring diagram?

I've tried to search for the answer, but H4 is too small to search for and things like Google just send me to HID retailers.

Thanks.

Canadian lights are the same as ours, those are probably European. Where did you get them from?
Before you install them make sure there is no issue with the beam pattern. Our US bugeyes didn't have much of a specific LHD beam pattern, but depending on what country these were from they could be RHD.
Assuming there is no issue with the pattern, you should be able to make up a harness yourself with the appropriate H4 and 9007 connectors. Check at www.rallylights.com for these, they may have what you need.

I actually bought them from Subydude a while ago and never got to modifying them until now. I bought them when they hada sale to clear out misc junk in the warehouse. He said he had a set laying around so I assumed they were off of one of the shop cars now with EDM projectors.

I put the original 9007's in and the pattern is really strange, but it appears to be slightly biased towards the right. I think this means they're for LHD, right?

Anybody know if they have the same required voltage, or will I need to put in some relays?
Does anybody have a diagram for how the pinouts on the 9007 compare to an H4?

Thanks

OK, so it looks like the 9007 bulb's pinouts (with the center pin upand going left to right) go: Low beam, Ground, High beam.

The H4's seem to go (again with the center pin up and reading left to right: Ground, Low Beam, High Beam.

Can anybody confirm this? Will I have any problems with a switching ground or a non-switching ground?

i thought the EDM uses H1 for low beam and 9005 for high beam
from the 9007, with the center pin goes up.
it should be from left to right. high beam, ground, and low beam.
that's how my 9007 to H1 and 9005 is set up.

They're not projectors. They look exactly like our US lights, but the bulb socket and seal are different.
