Ford Ranger TIM Controller

The new ECU for the Ford Ranger TIM (traction inverter module) is based on the openinverter design. It uses the original TIM's power eletronics, IGBT drivers, current sensors and voltage sensors.
So most of the information for the openinverter V2 board is also relevant for the Ranger inverter.
Just started to make the "Ranger TIM" Wiki, so most of the information is at the openinverter forum Ford Ranger section

Modifications to original wiring
MODIFICATIONS: (Please read the Ford Ranger treads, for details)
- Replace temp sensor in inverter
- Reuse old connector in inverter ECU
- One new wire, from backup light to inverter.
- Cut old J1850 bus, and connect to CAN bus
- Cut some wires going to accelerator pot, connect to BMS, cruise switch, oil sensor and display.
- Cut one wire going to the gear shift switch, use for 5V to the oil pressure sensor.
- Remove two fault lamps, or reconnect to BMS.
