welcome aboard

did you test the relay with a meter to see if the relay is good?

The older Cobras use the big relays like the old Ford starter relays. Make sure all the terminals are clean; and they have power and ground. From the remote control the blue wire is the up signal and the green is down. Sometimes the wires break inside the control.

Exhaust bellows not critical at all but the one above is critical.
You need to make sure each relay has power, ground and is getting the up or down signal. The problem can be in the connections at the relay or at the remote control switch/wiring
Concentrate on the blue wire that is the up signal to the relay

+1 on the wiring at the remote control, but if you're getting an audible reaction elsewhere to the switch activation, it may not be that. The hidden wires were pinched/damaged in mine, and I had to cut and splice.
