I took the plug out of the bottom of the headlight that used to plug into the original ballast. Cut the brown and yellow wires which is the power for the ballast. Yellow being positive, brown the earth. Where the hole in the bottom now is, i glued a strip of foam rubber and cut a slit in it to feed the wires through.
Since the igniter is built in, take the igniter off the bulb and use a AMP/D2S plug, $15 ebay.
Also buy some standard 2 pin 9006 plugs for the power.
I bought Hyluxtek 50w CAN BUS ballasts and have no codes. They were $50 each
