### ⭐⭐⭐⭐ Harness ok
*by C***S on June 15, 2025*

Decent harness but if you use in a application we're you use a hei distributor the wire labeled for the coil is way to small of a gage and some of the wires are not labeled But over all so far it works as it should . Instructions included are not very explained.
