I was trying to do an HID install this weekend on my 2004 wrx and could not get it hit to fire.

I took signal from the red (positive) wire. The stock unit takes input from the positive wire and there is a ground that connects to the body of the mount.

Is there something I am missing. Do i have to reconnect the ground somewhere?

 

See those are the two connectors.

I used the red(positive) to get signal to my ballast.

Any ideas?
