Ok, I need a 12V Power source and a ground under the center console (where the stick is).

What would I have to tap into but making sure I don't mess up the electical system.

Also, whats needed to setup a A/F Ratio Gauge?

 

I can help you with the question about the A/F gauge cause I have only ever looked at using the expensive WB O2 gauges.

However here is a pic of my 12V source and ground source that I use for my water temp gauge. The 12V source is in the cab next to the clutch pedal. The ground is under te shifter console, and I use it for both my boost gauge light ground and my temp gauge dimmer ground.



ground, left or right bolt on top middle of page (I used the left).

 

Can you like circle what you are talking about cause All I see are wires. =P.

hehe, sorry.

 

The top picture shows the fuse box just to the left of the clutch pedal. If you look just above the black cover, there are two connection points. The one on the right is a 12V ignition source. In ludeowner's photo, you can see that the red wire is connecting to this. Put a spade connector on the end of the wire, and plug it in.

For the ground, just use either bolt that the second photo shows (connect the wire directly to the bolt).

Hope that helps. I'll see if I can add some circles in his photos if you are still unclear.
