The long harness is back in place. I reconnected the trigger wire that was used with the old system. It also triggers the amp making it unecessary to connect a wire to connection 20. Current status is that Seicane unit comes on. Amp is triggered. No sound. To check for sound I turned the volume way up and set to AM and listen for static because the original unit was not working on FM.

My guess is there is nothing in settings that may be the problem? What next?
