No sound from radio

I've seen this discussed in other posts, but did not see a response about factory audio amps. Where is it located on a 2003 Winnebago Itasca?

Page 7 of the Front End Wiring Installation diagram for your coach shows the audio amplifier forward of the passengers feet against the forward bulkhead.

Found it! Right front corner under the dash.

If you are adept at wiring issues, can you tell me where these yellow speed sensor wires attach to?

Wiring Identification Guide says

GGW / 16 YEL GPS (GREEN/WHITE WIRE) VEHICLE SPEED SENSOR (CHASSIS SUPPLIED)

I didn't see anything else in the diagrams in a quick look at yours, but here they all are: IPL39T Wiring Diagrams.

Thanks again Chris!

Just found out from the techs at Brazel's RV Performance www.brazelsrv.com, who are closely tied to Workhorse, that the factory commonly uses one universal wiring harness for the model being built, and depending upon the features offered, will have an excess of terminals that are not required to be connected.

Brazel's is a great source for information!

I might guess this is true of almost all RV as each unit may have different options installed but the same wire harness. Digging around, I often find loose connections but that situation also has some hazard built in for us DIY folks.
When we find a loose end that has some form of quick connect on it, I always have to stop and look around a bit to see if it is something that has gotten pulled loose and is really needed or is it just a spare?
Once an RV has gone through a couple owners, there are often changes made that leave some loose ends to sort out.
