delco1946 Posted August 25, 2019 Author Share Posted August 25, 2019 All of the '81 wiring diagrams are here: Electrical/EVTM's/1981 EVTM. The Fuse Block & Circuit Protection pages tell what fuse supports what functions. And the Radios pages tell how those are to be connected. Rather than deal with 20year old fuses I just replaced them all. Radio and 8 track are up and running!its a bummer the PO cut up the face place where the knobs are for the last radio but it actually isn’t too noticeable for now. The horn however is still not working although at least the relay is clicking again now the the horn and radio circuit is energized again. Link to comment Share on other sites More sharing options...

On the horn, put a test light at the horn to see if it is getting power. If not, test at the output of the relay. Then the input of the relay.
