Just bought this kit from oreillys. Water temp gauge, volt gauge, and oil press. Gauge. I'm excited to put this on. Had a few questions. I bought a new thermostat water neck with plugs in it for potential sensors I'm guessing. Can I mount then sending unit to this for a good temp. Reading?
Also the oil press. Gauge has a hose, I don't want to mess with the original gauges though... the instructions state a t-fitting is sold separately to accommodate the new gauge sending unit, and to keep the vehicles original sender operational.

 

The temperature gauge sender is better put in the head or an intake manifold port than in the water neck. You'll have to do some plumbing to use a mechanical oil pressure gauge.

 

****.

 

Thinking about just removing the stock sender and just installing this one. It shouldn't mess with "the computer...right? That's what the sensor on the intake is for...right?

 

Yup, senders are for gauges, not computers.
