2001 Monte Carlo headlamp issue

I had a bad highbeam headlamp connector. I cut out the old one and replaced it without thinking much about the polarity, assuming it wouldn't matter. The bulb now lights up but is considerably dimmer than the other side (really no brighter than the parking lamp). I am assuming that this is a polarity issue but before I cut it out and redo it again I wanted to confirm.

Thanks.

(if it isn't any suggestions to why it is very dim would be appreciated)
