More tests
I unplugged the lamp on the way home Sunday morning. No codes. The PCM appears to be happy with a 450 Ohm resistor and the relay coil in parallel.
Surprisingly, it's looking like I'm better off...

It works!
I wired up a circuit today with a couple of relays, a couple of resistors, an indicator LED, the 12V light, a momentary-contact pushbutton switch, a cigarette lighter plug and some leads for the PCM...

No such luck, unfortunately. After work, I pulled apart the PCM output and TCC lead, turned to IG-II and put it in drive. No codes without starting the engine.
I'll hook the relays up this...

A minor setback
I didn't have time to wire up a couple of relays, so I wired up a simpler circuit last night: a Schottky diode (.525V forward drop) between the PCM lead and the TCC lead, and a heavy-duty switch...

A blinding flash of the obvious
Duh! How about plugging into the lighter socket instead of tapping 12V permanently? Hmmm....
I could connectorize the TCC cable and run it up through the ashtray. Put the relays, switch and...

Good to go
Frying switches, maybe burning fingers. I found a couple of 12V relays in my parts bins, so I should be able to use those for breaking the circuit instead. I should be able to use these for a crude...

Current draw is ~1.0±.03 Amps DC. I'll set up the speaker tonight to check for AC waveforms.
The cable I used appears to be 16 AWG (26/30); at a current draw of 1 Amp, 20 feet would come to a...

Hackmatic
I finally hacked into the wiring last night. I hated to splice into the OEM harness, especially given it's location, but it's the only way I had to accomplish what I wanted. It's my car, darn it,...

To revive an old thread....
After doing some more thinking and research in my Haynes manual, I located the wire for the TCC solenoid at the transmission end this weekend. To make sure I located the right one, I wired up an LED...

Ugh.
If getting at the ECU wiring is anywhere near as bad as replacing a heater core, I'd skip it. Ripping the dash out is a lot of work, and I'd probably screw something up in doing it. (Take...

Any indication of a service plug that can be used, like the pictures in the original link for the ECT? I'd rather clip onto a plug than munch up the OEM...

ECT Analyzer/manual TC lockup
