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.
