I have been using a Edge w/ Attitude for my guages, now I'm going to install a boost and pyrometer guages. How can I be sure the probe for the new pyrometer will fit the old Edge fitting in my manifold? Anybody know what size that is?

Thanks

I'm using the old Edge probe with Isspro guages. Works fine.

However, check this thread, I could be wrong.
