I still don't have a service manual
or any $. But do have an electrical cluster. I found the 10G red wire cut back 6" from the horn relay I can read contanuity from the wire to the fuse box but when I apply power to it the starter turns over. Everything has been routed around the fusebox. Breaks light are pluged into the side of a fuse on the ACC side of the box.
I know get a service manual.
Get this one. When I start the car the floor lights come on while the key is in the start position only.
Original auto car now 4 speed.
