when installing my aftermarket water temp gauge on my b14 am I able to just splice into the factory wire to the gauge or will that throw off the reading to the factory gauge/or aftermarket one?

If I'm reading this correct, you want to get the temperature signal for you aftermarket H2O gauge from the factory signal wire. I don't think that will work, as the aftermarket gauge is calibrated to its corresponding sensor, which works on a certain resistance reading. For example when I bought my VDO oil temp and H2O temp there were two different sensors to buy. Unless you can verify the stock sensor reads in the same range as the aftermarket, you will have to get the aftermarket sensor and install it in an adapter (Nissport makes one for the rad hose) or you can drill and tap one of the water-necks on the engine for the rad hoses.

I'm using one of these:

I didn't want to drill the water neck, and this part works great.

I was gonna get this, http://cgi.ebay.com/ebaymotors/Megan-1-3%2f16%22-Water-Temperature-Sensor-Adapter-RED_W0QQitemZ250402736365QQcmdZViewItem

megan racing makes my water temp gauge......just not really sure on the sensor threading.

The Custom Steel piece is WAYYYY better than that junk. It's machined out of solid aluminum and you don't have to run a ground wire.

The megan racing piece is pretty much the same as the Nissport adapter I mentioned. That is what I am running on my set up.

I should have just drilled and tapped the stock water neck. Almost free and effective.

Putting it in the water neck is the way to go. Those hose adapters are just adding complexity and extra points of potential failure.
