I decided to completely rewire the 145, since the old wiring harness was a complete rats nest that somebody had cut and spliced a million times. The schematic in the manual is semi confusing, as it's difficult to know if you're running the right wire to the right plug or slide on post. The safety switch on mine was present when I got it, but was unused and bypassed. None of the wires coming off the 5 wire key harness were going to the right place near as I can tell. The PTO switch the guy had only had 3 terminals, the book shows a 4 terminal switch. I was able to get a 5 wire harness with the right plug for the key, but I've got no clue if I'm wiring the right wire to the right device. Does anyone have a "cliff notes" schematic they've done? I found a 5 terminal PTO switch from NAPA that's as close as I can find to stock, some pics are below, anyone make heads or tails of it's configuration and if it'll work/which of the 4 wires that need to go to it will work?
