-The "front side" view is looking at the diagnostic connector in the car with the male pins pointing out at you.  The "​reverse side" view is looking at the connector end of our cable (looking "​into"​ the female sockets). 
- 
-Pin 12 should have connectivity to chassis ground. ​ Check that this is true. 
- 
-Pins 1 and 10 **should not** have connectivity to chassis ground and **should not** be connected with each other. ​ Check that this is true. 
- 
-Pins 1 and 10 **should** have connectivity back to pins on the ECU.  Check that this is true. 
- 
-For a 1G DSM ECU, pin 1 of the diagnostic connector should connect with pin 1 on the ECU.  Pin 10 of the diagnostic connector should connect with pin 2 on the ECU.  For 1G DSM ECU wiring information,​ view the [[http://​www.dsmlink.com/​images/​forums/​1GECUPinout.pdf|1G ECU Pinout]] document found on our [[ecuwiringinformation|ECU wiring page]]. 
- 
-For an EVO1-3 ECU, pin 1 of the diagnostic connector should connect with pin 42 on the ECU.  Pin 10 of the diagnostic connector should connect with pin 43 on the ECU.  For EVO1-3 ECU wiring information,​ refer to [[http://​www.ecmtuning.com/​images/​forums/​EVO%20I-III%20ECU%20COLOUR%20PINOUTS.pdf|this document]] put together by the fine folks at [[http://​www.evocoupe.net/​forum/​|www.evocoupe.net]].
