how would i connect output from a (used) timing loght pickup (automobile) to my sound card?

I'm looking at using a free software scope to watch the spark patterns
fromthe distributor. I always felt that told me a lot about my ignition.
I'll find a cheapold computer to use--maybe an old notebook with a sound
card. TIA Georg

A Google search will turn up several of the usual suspects for the
software.

If I wanted to scope my auto ignition, I'd go to eBay and pick up a used
scope. Almost any of the cheap "service" types like B&K would do the job. The
prices are often less than a cheap used laptop.

A 12 volt to 115 volt inverter, also cheap, would allow you to scope
without an extension cord.
