Engine sensors and wiring
Discussion
I am installing an LS7 engine in an Ultima GTR and using a MOTEC M800 ECU
I am building the engine myself.
I now have all the factory connectors / pigtails but am struggling to get hold of a wiring diagram / pin layouts for the main sensors.
Specifically does anyone know the pin layouts for CAM, CRANK, Oil Pressure and LS6 TPS and Coil packs.
On the coil packs I normally would just have two wires (12v and ECU taking to Earth) what are the other pins for?
Many many thanks in advance for any help.

This book contains wiring diagrams and pin info for the LS1/6/2 based engines. Cam and crank are hall, with +12v, grnd and signal. Oil press...havent a clue.
TPS is typical 5v, grnd and signal. Temp sensors are referenced to ground
Motec has information about the coils on their own website I think, tech docs section.
Then coils are a little strange, as they have build in ignitors. You should speak to motec about it, and how to configure your ecu to fire them.
