That was one of many warrantee items in 2014.

My 2 cents....

The diagram of the BIRD does not look generic to me, at least for that particular model. All wires to the microprocessor have to be installed in the right location or it won't work as intended.

I agree the wiring is simple. There is one wire from chassis to measure engine battery voltage. Another wire from house battery is used to measure that battery voltage and also appears to supply BIRD power. Another wire is output to fire isolator relay when needed. There is the ground. The fifth wire is a auxiliary engine start in case the chassis battery is dead and house batteries are good enough to start the engine. That wire should force microprocessor unit to bypass most or all program logic in order to jump-start the engine.
