Old RZT50 Kawasaki, where's my parking brake relay?

[RustyBucket]

When I turn the key I get a red light "PARKING BRAKE" warning and no turn on the starter. I unplugged the parking brake switch under the p. brake lever and have NO circuit to the switch. I read a little and see there is a parking brake relay hidden SOMEWHERE.... maybe bad relay or maybe I pulled a wire off of it, I was mowing some pretty rough stuff. I'd mowed awhile the other day, parked it in the shop and came back out to finish when it was cooler. Still trying to get to run so I can finish. I think the mower is a 2004.
THANKS IN ADVANCE FOR YOUR HELP!!!
