I finished all firewall forward engine wiring today by terminating the the EGT (4 ea.) and CHT (4 ea.) wiring probes. I also verified the Key start / magneto grounding wiring and caught one error which was that I did not have the ignition key ground wire attached.
That pretty much wraps up all wiring for the G3X system and firewall forward, which was about a four month process for me. Everything is pretty well tidied up too. Just need to swap out for some high temp zip ties in a few areas.
