How do I turn off my seatbelt alarm in my Wrangler?

I just installed a 4-point harness seatbelt system in my 2008 Jeep Wrangler and the alarm won't stop going off in my Jeep. It's driving me nuts and I cant do the turn off the ignition and buckle it 3 times thing because I took the old seats out that had the buckle attached. Can anyone help?
