Flasher to Signal Lever Harness to Blinkers
 

It has taken me a week but with the help of others on MLU I figure out the wiring connector letter/number code positions between the signal lever/flasher harness (female Packard connectors labeled as (460, 461, 460-22, 461-22, 22 & 460-461) and the male Packard blinker wires labelled as (A, B, E, J, K & L) ...they are connected as 460-461 to A, 22 to B, 460-22 to E, 460 to J, 461-22 to K and 461 to L. This wiring works for a M38A1 but I it may also work for a M151 and M715.

Hope this helps others,
