Knock Sensor Pin-Out

02-23-2020, 01:28 PM

Installing a 550-601N in a Third Gen Camaro. Factory 1-wire knock sensor. Holley instructions say Pin A (sensor #2) wire A21, Pin B (sensor #1) wire A29. But in the schematic, is shows knock sensor pin A going to A29 (Knock #1 In), and Pin B going to A21 (Knock #2 In). Typo maybe? Any suggestions?

Correct, that's an error in the instruction manual. The wiring schematic is correct.
