1 Our vehicle has a 7 pin round plug on it. The van we looked at had a flat 12 pin plug and a separate Anderson plug. The manufacturer gave us the paperwork for the auto electrician to adapt the wiring for a 12 pin plug - but then said we could probably leave the 7 pin plug and have what looks like a double Anderson plug wired to the car.
The4 and 12 ground pins on a SATA power connector are longer so they make contact first when mated. Similarly, SATA devices have longer 3, 7 and 13 power pins for the same reason. These 7-pin to 7-pin transition cables, like the P952-18i, connect external devices with an eSATA port to an internal SATA controller.
TheIOREF pin is there purely for switching between 5V and 3.3V on the IO pins. DO NOT CONNECT 12V DIRECT TO ANY PIN EVER!!! nickn4 March 9, 2013, 12:26am 5. 7-12 Volts" so at the beginning I guessed yes but then I also found that "input pins operate on 5V". The 7-12 volts goes into a voltage regulator which turns it into 5Vftk8C.
