I received a new EGT probe from MGL today (for free!), as the previous one wasn't working. I tested this new one before installing and it worked (hooked it up to the RDAC, turned on the EFIS, and put a lighter under the probe).
Installed the probe in the exhaust. Again, the location would hit the cowl, so I bent over the probe with a vice and small sledge hammer.
Routed the wire through the baffle, over the engine, and down to the RDAC. Barely enough wire to get there.
