Rotormotor FC3S

Early days on my engine rebuild and upgradesl mods.
Ditching the stock ECU for aftermarket one for tunability and insurance over my rebuilt engine.
The 5 speed gearbox sensors and reverse switch, the factory water temp, boost/oil pressure and alternator wiring to stock dash gauges will remain.

Removing emissions as well as not required in my country.

I will add extra separate standalone gauges and tacho later.

So..to clean up the existing loom and remove a bunch of cabling, do the above signals to dash cluster run thru the ecu or straight to the dash as in No direct link to or thru the factory ecu.

BTW my FC is JDM Rhd so ecu be in a different location to Lhd US spec.

I did have haynes manual but bugger if I can find it..

Cheers for any pointers.
