Help please

Hi guys, been a while since I've been on here, but I'm about to upgrade my headlights to a clear light with H4 bulbs, and my question is this: Do I need to use the upgrade harness with the relays or would the stock one be fine now until I re wire the car in winter. Thanks

I replaced my headlights with lights that incorporate H4 style bulbs in my previous camaro without upgrading the harness or anything.
