Hi guys,
I know that many people prefer putting a pyro sensor pre-turbo. How about tapping the crossover? It is certainly very accessible.
Sincerely,
Rob :)

Some have done it there, I think Kennedy sells one that works well in that configuration, I also like NVMNTLION's location in FAQ

TT,
When I installed my it was pre-turbo, it's really not hard at all. I want say that it me about 1hr or a little less to do it. Most of the work is just removing the wheel and inner finder and putting them back on.
NVMNTLION made a GREAT write up on how to That what I used when I installed mine. Read it while looking at the stuff to remove then read it while doing it. Piece of cake.

TT: I put mine right in the exhaust manifold runner coming out of the back driver's side cylinder, right before the flange connecting to the crossover. I didn't have to remove the wheel well, and didn't need to use any extra length of probe wire because of it's close proximity to the firewall. I just jacked the truck up a little on the left front to give myself a little room to work in the wheel well, and drilled and tapped the manifold thru the wheel well, between the wheel well and the top of the frame.
It's a darn good pre-turbo location, measuring egt's right out of the cylinders in the warmest part of the engine, and the pyro shows instantaneous readings when I'm on and off the go pedal. Other probe locations may result in slower pyro gauge reactions to actual in-engine egt's.
Drilling, tapping, and installing the probe where I suggest only took 15 minutes once all the tools were gathered, and I'm a shade-tree at best. Installing the gauge and wiring took up the rest of the install time.

W_Huisman, that's brilliant! That sounds really smart. Can you post a quick photo when you have a chance?
Thanks for the response. Very helpful!
