As I'm preparing to rewire the engine compartment of the 66 Toro, I read some posts, especially from ourkid2000, alluding to mistakes in the 66 CSM wiring diagram. I've looked at a 67 CSM diagram and couldn't see any obvious differences, but I didn't compare them side by side. Is there a thread I can follow that has these differences identified so I can make sure the car is wired correctly? Also, I see the diagram for the 66 shows a resistor in the ignition switch and the coil. Can anyone tell me where these resistors are? I cannot recall seeing one near the coil or the ignition switch. Were they originally inline resistors? Thanks for all the assistance.

In the '66, look at the wiring to the tail lights. One black/white wire goes to nowhere. Also, look at the wiring going to the tail lights. Black-Yel goes to five lights (3 left, 2 right), while another dark green wire goes to the 6th light. I don't know what they were smokin' when they drew this one. They corrected this mistake in the '67 wiring diagram.

More:
- No fusible link off the junction block shown, while they were produced with fusible links.
- The colors of the wires on the cluster connectors are wrong.....completely wrong.
- Unlabeled switch above the headlight switch (this is the interior lights on off switch.....no dome light in this car but similar thing).

On '66 Toronados, with manual AC at least, the wiring for the blower motor isn't shown anywhere in the manual. We figured it all out on here a few months back. That's all I can think of for now but I'm sure there's more I've forgotten about.

The resistor for the coil is a "Nichrome resistance wire" spliced into the ignition wire. It starts maybe about 2 feet before the termination at the coil + connection and I think it's a white wire with red and black cross pattern in the insulation. That little length of wire drops the voltage to the coil when the engine is running to like 9V or something. I haven't stumbled across the resistor for the voltage regulator yet.
