Where is the fusible link on a ’66 Toronado?

I'm not sure if it has one. If it does its probably on the red wire that feeds to the bulkhead connector from the horn relay at the horn relay side.

Thanks, would that be on the engine side of the firewall or under the dash?

As oldcutlass said, there does not appear to be a fusible link in a '66 Toronado. In looking through the electrical section of the '66 chassis service manual for the Toronado, I can find no mention of a fusible link.

Here's a portion of the '66 Toro wiring diagram from the '66 service manual. The junction block is shown at left, and none of the wires coming off of it pass through a fusible link.







Here's the '66 Toro fuse usage chart. Nothing shows a fusible link, including the heavy duty power draws shown at the bottom (headlights, A/C, etc.). Each has its own protective circuit breaker in various locations.

How about we go about this another way. What is the electrical problem your having that brought this question up?

1967 was the first year for fusible links in GM cars.

Thank you very much for this good info and diagrams; it will be useful now and in the future,,,

I was just about to do that when I was informed that was no fusible link on the '66 Toronado. The reason I asked is because I would be cruising along about 40 mph and all of a sudden the engine would shut down, as if I ran out of gas, which of course I did not. This had happened about a half dozen times to me, after the car sat for several minutes, it would start right up and run fine; since I only drive in the day light hours, I wouldn't have any lights on and can't say if I noticed any of the gauges shut off, just wasn't watching for that at the time, only to get the car safely to the side of the road,,,

Intermittent gremlins are a pain. Check your coil wire connections to start with.

Check: Wiring connections at the coil, then coil itself. If those pass muster I think it will be in the distributor. My 69 Toro used to do that exact same thing; upon pulling the distributor I found a poor connection on the coil trigger wire that the advance plate would sometimes kill completely.

May be time for a distributor rebuild.

Thanks for the suggestion, I've been thinking about getting a new aftermarker HEI distributor anyway, one with a conventional cap so it looks more like the original, being in the back, it hard to see anyway,,,
