The power source for theseis fuse 8. From fuse 8 it goes through a pair of contacts on the main relaythen is distributed through the harness to its various points.Sorry, it's a 1500cc Honda GW Aspencade and the indicator for the gas, temp overdrive and reverse isn't working. I checked to see if it was a fuse that evidently controls them all was alright, and it was. I think maybe it's a loose wire. They seem to be on the same circuit. Help!
