What Harold said -lighting kits were only dealer optional accessories on the N-Series tractors. However, the OEM Ford 9N/2N Essential Manuals have wiring diagrams to use as a guide. You don't tell us, so I'll ask. Do you have the OEM 6V/POS GRN setup or has it been switched to 12V? If 12V, verify your lamps are 12V too or else you will smoke them at first power up. If 6V you should have the 1-Wire/3-Brush generator (after s/n 12500) using the roundcan cutout, front mount distributor (goes without saying) and the ballast resistor. The starter motor also is only a 1-Wire unit and des NOR use a solenoid. You don't need Amazon to buy parts from. Dennis Carpenter makes OEM exact-as-original parts and also sold at JUST8N's.com including all the wiring harnesses and lighting wiring kits.
