Where to hook up Tach on 82 toyota to set idle

[DenCo40]

I have a broken tach on my 1st gen pickup. I have been working on the carb and need to do some adjustments (idle speed and such). Where can I hook up my diatgnostic tach? I have been searching but haven't found any definitive answer....Thanks in advance!

The ignition coil, that's the location for a stock first-gen tach feed.

If you've got a FSM, feel free to use that, otherwise, I'll take a look at mine, and post up later.

Yeah, man!

for me, there are two wires coming out the base of the coil, they tie into a Toyota connector that leads through a bulkhead plug into the cab behind the gauges.

If your tach's in good shape, then it's worth splicing it back into those lines, and keeping around. I'm pretty sure I use my tach more than anything. Especially now that i don't have a speedometer.

Yeah My tach is fried. Hasn't moved since I bought the truck. I figure I will just buy a used one that still works one of these days. would be nice to have. but for now I just need to know rpms...I will look at those wires and try to hook into one of those and see if my dianostic one will pick up a reading.

Good luck man!
We're keeping the first gen spirit alive.

There should be three wires comming off the ignitor. A white one (turns brown at the connector), a yellow one and a black one. The black wire is your tach lead.
