I am about to put 3 new guages in my car and I was wondering what is the correct way to wire the into the fuse panel??

 

I would simply splice into the pink/black wire going to the instrument panel and replace the gages 10A fuse in the fuse panel with a 15.

 

The most professional way would be to un-bolt the fuse box and let it hang so you can access the back of it. Then take out the connector prong in back of the fuse box that goes to the gauges fuse. Get a new connector prong and crimp the additional wire in, along with the other wires.

If you do it that way though, you'll have to find the special connector prong which probably only gm has and you might not be able to get it from gm.

But really, it doesn't matter where you splice at. The factory wiring has splices all over and its just crimped, then soldered, then has crappy electrical tape thats almost like duct tape that covers it.

I would do what pmpn said to do.

I would also use solder to connect the wires together then use heatshrink tubing to cover the connection. If you don't have a soldering iron or heatgun then get some crimp connectors and splice in that way.

 

Let me put it like this I have new auto meter gauges that im putting in and I already have all of the sending unit in place ofr them and the stock gauges are staying. How would I go about wiring the new gauges into the fuse box for power and ground ect..

 

See my above post. What's the fixation with the fuse box? It would still be fuse protected. Splice/ solder/ heat shrink. If you are putting them on your A pillar it should already be grounded and all your sensors are grounded if they are touching your engine block/ transmisison.
