These are for:

2002 JDM HID Sti factory ballasts
Wiring into 2002 US wrx

Would the ground be the Large Black/Small Orange combo, or the Large Blue/Small Brown combo? The Large gauge black wire used to be a part of the bulkhead harness. the Small Orange wire on the other end goes to the ballast.

I've already done quite a bit of searching and reading, but no one seems to mention which wire is the ground on a real JDM HID ballast.

The other side looks like this w/ the Ballast:

Logic would say assume the large black wires are the grounds and assume the large blue and large red are the power wires. But with expensive ballasts assumptions are never good

This thread was of good use as well:

Thanks in advance
