Horn Relay Location

My reference Buick repair book doesn't state where the horn relay is located on my1991 Park Ave Ultra. Can someone tell me where this rascal is located?

Thanks

open the hood, and look near the firewall, see a black plastic cover with "maxifuse relay center" printed on it, pop that sucker off, and it should be in there!

I suspected that the above location was where the horn relay could be
located after submitting my question, but none of the 6 relays had any
identification as to what they were for. In checking the numbers on the relays, all were identical. So, I pulled one off the end of the row and moved everyone over one with no negative effects on any system com-
ponet. However, pushing on the horn areas on the steering wheel has
no effect. The horns themselves work when jumped to the battery. So..........

1. Which of these six relays is the HORN relay?

2. What is the simplest way to check the circuit from the steering wheel
to the relay?

look for the relay with two orange,green and black wires
