Description

****READ ENTIRE DESCRIPTION BEFORE ORDERING Used ignition coil harness. This harness is from the square truck coils (ACDELCO D581) and truck brackets, and is a 3061 harness. This will correctly conform to D581 coil brackets, but this harness will plug into D514A, D510C and D585 coils, just not contour to those coil brackets properly. This harness fits either cylinder bank (1, 3, 5, 7) or (2, 4, 6, 8). You must properly identify cylinder 1 or 8 when installing this harness, otherwise the coils will fire in the wrong order. Price is for 1 harness. The item in the photo is the exact item being sold. NOTE : There are 5 different factory LS ignition coils, 2 coil harness connectors, and 4 different ignition coil brackets and 6 different coil harnesses. You cannot mix and match coil harnesses on brackets, the brackets are specific to each style coil and so is the harness. Make sure you are ordering the correct coil harness for your application!!
