Have rechecked schematic for ignition power distribution pin pattern for chassis 124.030.
Findings are that the previous info posting is correct..
Of particular interest will be pin 50/violet wires [ 2]. These are the starter circuit feed and will only power when key is in the start position.
I would suspect either crossed/shorted wires , incorrect pin location, or bad ignition switch..
Try the above and if that does not result in remedy, I will try to get the schematic to you............
PS .. I also note that you have a gn wire to feed dash lamp circuit, whereas the CD states this wire to be gn/w.......????????
