Right, harness straight.

Pictures below, right to left: (2X) twin tube snap connectors at input end. - First break-out of short wires at 11-inches.
Short wire output tips. - Long wire output tips at 31-inches.

The original main harness brings two wires to the low note horn on the right side of the car as factory issue. High note horn goes on left side with a mirror image mounting bracket. Wiring between the horns is a separate accessory AHH5453 Harness -horn, four 16-ga wires, two short 15" and two long 31", cloth covered horn harness. Brown/Green for the power wires, Brown/Black for the ground return switches wires, one long and one short in each color.

All four wires start together flush at the input end. A few inches along they branch out, two short wires in one branch, two long wires in the other branch. All four wire ends have bullet connectors. The horn harness will be attached to the frame with two rubber straps, AHH5506. The horn harness cover should be same as the main harness, black with yellow tracer threads.

If you are a concours enthusiast, then also pay attention to how many black and how many yellow threads in the braid pattern. This is also on my web site, but if your harness maker is already doing this, they should already have that information.
