You're on a Toyota COP, it appears, which are notoriously difficult to test with a secondary pickup. Strange as it sounds, but you may have better luck with just an alligator clip. Here's a couple threads worth reading:

There's no instructions to link to. It comes down to fishing the pickups out of the distributor, then grinding enough plastic off the outside to remove the mounting bracket and magnet. You're left with the pickup coil itself and the wires connected to it. Connect one end to a scope channel, and the other to ground. I'll try to grab a picture of mine at work tomorrow.
I will say that the wires are quite thin, and in your case, 20 years old. :lol: They have a tendency to break if they're not braced/secured. A setup like Noah's will stop the wires from flexing too much.

The magnet is still in there, so start grinding on the end furthest from the wires. Eventually you'll uncover two Phillips screws that hold the magnet on. Spin them out and you're home free.

Here's the one I made if you're interested.
"Ground cannot be checked with a 10mm socket"

"Stackable banana plugs" should pull them up on amazon and ebay. It's either those or "safety banana sockets" you really need for something like that pick-up so you've got a female to plug your test leads into. If you use regular plugs then you'll also need couplers to connect them to your leads.

Pretty sure I got those from Digikey:
www.digikey.com/en/resources/connectors/...a-and-tip-connectors
Their site is horrible to navigate. :silly: But they have a huge selection of quality stuff to choose from. If you want to be specific, these are the ones I ordered:

To be honest, I wouldn't get these again - they're excellent plugs, but the stacking feature isn't needed for the secondary probe.

Absolutely, as long as it's a two-wire coil. Three wire or more won't have a primary waveform that can be tested without tearing the coil apart. :silly:
