Unidentified MV Wiring Harness - Possible M422

[Krempely]

I have three of these wiring harnesses and planned to use them for spare parts for my M151 and M37 projects. Can anyone identify them by the pictures attached? The waterproof bag and cardboard box inside had no tag(s) or identifying information. The wiring is pliable and like new; no soft spots or cracking felt when flexing or straightening the harness/wires.

I will trade for M151 and M37 parts.

Isn't that a turn signal conversion harness? See if the cannon plug fits into the turn signal control. If the cannon plug fits into the three lever light switch, it is a lighting harness. The two prong connector goes into the brake light switch on the master cylinder.

The cannon plug does connect to a three lever light switch.
