What does this wire go to? (Ignition Coil Assembly) (1 Viewer)

I don't know where this is supposed to be plugged into. There's nothing I can see around that area.
I searched the threads and seen other pictures that are also plugged into nothing...

Well why you are searching it really help to have the year and market plus the model. Then you can look at the wiring diagram and usually figure out by location and the color code what it is.

Free downloads of perhaps just the manual you need. The Haynes book has wiring diagrams for most stuff.

Possibly a Tach signal for the emissions computer and/or AC amplifier. Is it connected to (-) side of the coil?

I thought that was part of a 'radio kit.' There was a capacitor attached to that wire, so when the coil fired, it would cushion-out some of the noise that you would find in a radio speaker

My first CD-stereo sounded great, then it got wet from the cowl-body seam leaking, and turned itself on with the help of some liquid-electrolyte. No problem, just the circuit for settings, time, etc. - the all-the-time power, got me sketched-out. So, I figured, well hack a pair of 12V computer speakers that have an internal amp, and hook them to something digital, like a phone, and swap the second computer-speaker for one that I had installed with the in-dash head-unit. That was okay, but, especially when it was charging from the cigarette-lighter, wow, you could hear a constant tone that changed pitch with engine-rpm - like an auditory tachometer, which was kinda neat. Then, I decided that there is really nothing to listen to anyway, and pulled the audio-equipment. So I'm currently appreciating the hole in the dash, with some wires visible. That H42-transfercase makes its own music; it reminds me of the old UPS trucks. I have a couple of "TOYOTA"-badges, which I cut-out from the original, mouse-chewed, heel-hole-torn, cracked, heat-shrunk, and rust-stained front floormat - I'm thinking that will be close-enough for a radio-delete plate, and that my trimming with scissors will be obvious, but, whatever. I might do some switches for extra lights, or some gauges like tach, volts, and O2-sensor read-out, but, I'm really appreciateing the it's-still-all-stock just missing-the-radio-look.

If radio noise suppressor it would connect on the (+) side of the coil. Trace it back and see where it connects.

I said capacitor, I think it is a condenser? Post #3

 

[Engineer8000]

same thing. condenser is an older term.

It's a 1975 with the 2F and 4spd.
I bet it could be something to do with the emissions as someone stated. PO removed the smog pump, but EGR air rail and some of the emissions stuff is still on it.

Both of my '75-engines were fully smogged on the spark-side of things. The igniter, coil, and resistor assembly was connected to nothing on that wire, this question comes up every so often. Looking at the old photos, there was no capacitor / condenser on the '75 distributor; I thought that a capacitor was for early distributors / coils, points without an igniter?

Could this also be where the Toyota-dealer Service Department connected their tachometer / dwell meter? In effort to keep the service-person from getting near the "don't touch resistor is very hot"
