Yea power window question

[53burb]

I have a 2007 Ram ST quad cab. It came with no power windows/locks. I added the stock power window regulators to all the doors. For switches for the front doors, I added a switch kit from A1 Electric. I asked them a couple of times if relays were needed and/or recommended for their switches. The said no both times.
The rear doors, I added the stock switches and I added relays. They go up/down real quick.
Anyways, I know that the setup isn't on a 67-72 Chevy, but maybe the info about the relays will help.
