Right now I have the headlight wire attached to the terminal for power to the headlight switch (#12 on instructions). As for the instrument feed, I haven't changed that yet, but was going to. That terminal is fed by a 10 amp fuse. Should I change that, or leave it as is?

The horn relay, I used the Painless one, but would very much like to keep the buzzer. So, I need to keep the violet wire hot? Also, what about the black wire from the instrument panel? From the 1970 Plymouth Valiant wiring diagram, this wire feeds the electricity to the printed circuit connector, which (I believe) feeds the voltage regulator for the instruments. On the rallye cluster, the voltage regulator is built into the fuel gauge. Does this wire need to be attached to the fuse block at the dash B+ terminal (#11 on the instructions)?

I know, lots of work on your part. But, I don't think I could make this work without your assistance, so I hope you don't mind all these questions!!!
