Customers are mixed about the diagram. Some find it helpful to print the wire diagram online, easy to understand, and etched. The convenience of color-coded wires greatly simplifies the setup, reducing the likelihood of errors or confusion. However, others say that the diagram is not helpful, labeled incorrectly, and provides contradicting information.

CONFUSED about photo REVERSED #85 & #86 and "Wiring Specifications."

CONFUSED about photo REVERSED #85 & #86 and "Wiring Specifications."
Image 5 from top - shows a REVERSED wiring directions for position as Positive TRIGGER #85 and #86 as the GROUND, then contradicts this, under "ABOUT THIS ITEM" under Wire Specifications: shows the Black as- Ground (#85), and the Trigger as (86), Yellow. I know coils are reversible, BUT b/c of the CONFUSION, I will RETURN for REFUND.
