Factory Tach Wiring Harness

I have what I think is a factory tach harness. It has a red and brown wire. I am pretty sure the brown goes through the firewall to the distributor. The red actually has two connectors. Where and what goes to the two connectors??

The one at the end goes to the fuse box to ignition unfused, and the other connector is for your cig lighter,or radio, or anything you need to make hot while the ignition is on.
