POWER ADAPTER HARNESS
Now that you've done the ground harness, the power will be easier. This is for the right side:
1. Take factory turn-signal cable recovered from old turn-signal and cut off 1/2" from end of Lb-light blue wire
2. strip 10mm insulation from the ends of Lb and Lb/W wires
3. take diode and cut leads from both sides evenly so you have 1" length
4. place diode in-line with Lb wire with Lb bare-wire overlapping diode lead (end with silver-ring facing away)
5. twist wire over diode lead and solder together
6. slip 1" of 1/8" heat-shrink tubing over end so it covers the soldered joint and diode body, leaving 1/2" lead at the end
7. twist bare-end of Lb/W wire over end of diode lead and twist together
8. cut an extra piece of wire to GAP-X length + 2-4 inches extra, strip 10mm insulation from both ends
9. crimp a
female connector onto one of the ends
10. with the other end of the extra wire, twist that end over the diode + Lb/W combined twist (all wire-ends face same direction)
11. crimp a
female connector over this twisted end, then slip a 1" section of 1/4" shrink-wrap over that joint and connector. Heat to shrink the wrap
12. plug the connector with the Y-connection into your yellow/male power wire of one of your lights
13. plug the other connector at the end of the extra wire into the other light's yellow/male wire.
14. plug 2-pin square-connector into factory harness
15. Then repeat for the left side. The complete wiring will look like this, four separate little harnesses. It actually doesn't matter which light you plug into which connector. I swapped between the flush-mount & mirror lights on each harnesses for simplicity in drawing the diagram. You can have the Y-connectors going to the same light to keep the wiring clean:
Remember, it's easy if you look at and do just one wire and one connector at a time. If some of the steps doesn't make sense, I can add pictures.
