I have a THAR-FORD2 Rev.1 Lot 50317 T-harness. The harness has a yellow wire, grey w/black wire and light blue wire that are not terminated to a connector. All other wires are terminated into connectors. The Light Blue wire comes from a micro relay that is part of the harness. The Grey w/ Black wire is teed into the dark blue wire that teminates into the micro relay. The yellow wire comes from the bundle in the loom. In guides # 59241 and 59411 the guides indicate there should be a Yellow, Light Blue and LIGHT BLUE w/ BLACK wire. This harness does not have the Light Blue w/Black wire, it has the Grey w/Black wire. Should I use the Grey w/Black wire in place of the Light Blue w/Black? I want to be sure so that I do not damage the EVO-ALL or the vehicle. Thank you.
