where do I drill and tap to install the thermcouple for my pyro? I thought that info would have came with my new gauges but nooooooooo

 

There are plenty of posts with links to the install of the probe.
Here's one on the Piers site

I just did one last weekend and it was real easy. The hardest part was getting the turbo off the exhaust manifold.

thanks Den, and what makes me realy feel dumb is I ordered the gauges from piers

 

Might want to pick up a exhaust manifold to turbo housing gasket. Around $2

Just as an addition to those instructions...drill straight and when you do the tapping don't go too far, it's a tapered tap and you don't want to make the hole too big or the pyro insert won't have a tight fit. You are trying to get about 3-4 full turns on the pyro fitting. That is enough thread to hold for you and will make sure that you don't have an overly large hole.
Also, try to keep the pyro tip about 1/2 way down the passage and be sure that you don't let it touch anyting...like the bottom of the manifold passage...it has happend and they can break if you do that.
