Default Where does the ECU Ground? LC-1 related.

I'm installing my LC-1 WB and need to run the ground to the same ground as the ECU. Does anyone know if the ECU is grounded to the body or the engine? I tried searching, but couldn't find anything. How did everyone else hook up their LC-1? Did you use a relay for the heater wire or just tap it into an ignition on wire? Thanks

The ECU is grounded to the chassis right where it bolts in under the passenger carpet.

The motherboard has two ground planes on either corner of the case near the front where the plugs go in. If you connect to one of those two spots you should get a common ground.

Nice. I might have to run a ground wire from the corner to the engine block.
