1		9
2	Bus positive Line	10	Bus negative Line
3	Speed sensor SD436-1	11
4	Chassis ground	12	Airbag
5	Signal ground ("Sensor ground")	13
6	CAN high (ISO 15765-4 and SAE J2284)	14	CAN low (ISO 15765-4 and SAE J2284)
7	K-line (ISO 9141-2 and ISO 14230-4)	15	Battery voltage This should be L-line (ISO 9141-2 & 14230-4) but according to Hyundai diagrams it's called DCT and provides 12v+ from BCM's "V-PUP"
