For the moment I'm turning the horn relay 180* and using a jumper for the horn, which will not function for a while anyway since I'm temporarily using a cadillac steering wheel and can't figure out the connection at the steering wheel for the horn.
lots of little things to hook up; I started the car and its running, sounds fantastic, seems like the engine wants to rev. in a good way!
tonight I have to repack wheel bearings in front, plug everthing into the dash, see if the lights work - maybe pull it out under its own power for the first time since '84 when some california hot rodder took the engine & trans and left this poor GS to rot.
