it connects to the red and yellow wires coming from the edge box

you drill it where the exhaust manifold meet the turbo flange, and yes put it on the back side where the 4/5/6 exhaust cylinders would flow out through.

heres a pic of where to drill it, its in the lower left part of the picture.

yes the temps will be lower after the turbo, its usually around 200 degrees cooler, until you get up above 1000* then its around 300* cooler

PRE POST TURBO
600 400
700 500
750 550
800 580
875 620
900 640
1000 700
1100 750
1150 800

As you can see, there is a 350 degree difference at the upper end of the scale. Based on this, I would try to keep the post readings at 900 or less if that was the only reading I had. I used to push it to 950 and a little higher when towing which put me up at 1300 degrees. Sure glad I put the new unit on as it is a much more realistic reading!
