i took me a while but i figured out the horn. first the relay was bad so i took the cover off and degummed it, the plunger wasn't moving, i moved it up and down and put some p b blaster on a q tip and ran it up and down the plunger and it works now all i need is the wire to the center pad i think all that was disconnected when i got the car. the spring is there and the little plastic twist lock is there and the little brass part is there i just need a wire. i also figured out the blower motor it needs the relay and power to the brown wire to the master switch. one brown wire is 12v to the switch,the other is 12v to the blower speed switch, the green wire in the center goes to the pressure switch on the accumulator. i found my cheap harbor freight test meter,right where i left it. i also figured out why my turn signal sounded crunchy,when i had the steering wheel off i noticed one of the springs was missing and i found it i will get one at pull and save or just buy a new switch the old one is 35 yrs old along with the dimmer switch which doesn't click. the inlaws were over today so i spent most of the day outside in the car.
