If you don't have a tach you shouldn't need to hook it up.

The computer does not need the oil pressure to run. I kept mine because you can read it through the OBDII port.

Re: Few more harness querstions

Then you only need to hook it up if you want to see the rev's, otherwise don't worry bout it.
