The thermocouple probe for my pyro is in the downpipe. I'd like to relocate it to the drivers side manifold? Any issues with this? I know not to cut the lead wire. There are not special probes meant for post turbo are there? Also how the hell did you all get a drill and bit up in there to drill the manifold. Mine is an Isspro gauge and I think the thread for the probe is 1/4 npt. Needs a big hole to tap and it's a long bit.

 

I had my manifold off when I "tapped it" . I was fixing an exhaust leak and doing my up pipes. But a drill will fit in there just fine. Remember to wear safety glasses, collar shirt, long sleves.

 

Tapped it! That's a good one!

 

It's pretty easy to get to, really. Drilled mine from underneath the truck. This is 1/8" npt. I believe that is the most common size.
