I have a 66 model 1206. The transmission lube pressure light is beside the key switch like the 56 and 66's. Every 1206 I've seen is like this. According to the wiring diagrams only the 1206 had it like this. My 67 806 has it wired in with the engine oil pressure light inside the fuel gauge cluster. Also the wiring diagram for a 706 and 806 is like that. Just wondering if the 65 models were the same, and what the other tractors you've seen or own had. Maybe it's was just something unique to the 1
