how do you hook up a exhaust temp gauge? and also why does it matter what your exhaust temp is?

 

You hook one up by welding in a new bung.

It matters because if you see the temperatures increasing under load, and then suddenly dropping, that's a big sign of detonation.

 

I believe most company EGT that you get come with there own bung, i dont think the o2 bung will work. Also if your a b series you want it on the number 3 cylinder because it gets hot the fastest.

Bah, that's what I was thinking of. Yes, they do come with their own bung (USUALLY).

 

You sure its not red green blk? Did it come with any instructions?

 

Wait, you got an EGT gauge, and you didn't buy one that came with a probe?

No. You really seem confused. An EGT gauge uses its own temperature probe, which is installed in the exhaust stream (normally somewhere on the exhaust manifold / header). This probe connects to the gauge, and the gauge is then also wired for power, ground, and illumination.
