Details:

Has numerous repairs / splices, later fuses, aftermarket headlight switch which is broken, and has a solenoid wired into it. Definitely has been cobbled together and is sold strictly in AS-IS condition for parts only. Also an exact replacement for 318s with serial numbers 420918 to 4750 and 420s 420153 475000. Harness is JD part number AM100237 which no longer available from Deere.

Wiring harness from a 1987 JD 318 Lawn and Garden Tractor which I purchased after the previous owner seized engine. Priced accordingly. No idea why since the starter worked correctly when I removed and tested it. Harness is an exact replacement for 316s with serial numbers 420548 to 475000.
