Judging from the TC/TCS workshop manual, it is on all TCs. It's on page M-12 of the workshop manual. I wasn't able to find it in the parts manual. That's not to say it's not there, just that I couldn't find it. My car is farily late (3635R) so of course it has it. The bulb is very small and it fits in a plastic socket, IIRC. If you still have the mounting bracket for the heater and choke cables, there should be a slot between where the cables mount. That's where the light comes out. There should also be a clip that holds the bulb and socket so it shines out of the slot.
