Bob,
Took a few photos, pulled out a spare harness & photo-shopped a bit.

I didn't have the connector to plug in to the receiving end of the plug shown, so I trimmed the end of the tach lead & tinned it until it fit snugly into the harness end of the F connector. After it was fitted, I threaded it through the cap, pushed it into the harness side & slid the cap down & installed it. The black retainer holds the wire in just fine & never had a problem. No cutting or splicing into the harness.
