Today I was able to complete the wiring of the final "engine" connector, then I swapped the power wire for the fuel pressure sender from GEA24 J243-4 to J243-3 - 5V to 12V. The fuel pressure now reads 0 PSI. Later in the day I removed the mount for the engine connectors to allow access behind the engine for tidying the wiring looms, another couple of hours work should see it ready to install the EGT wires.
