Pull the old harness out toward the front, leaving the string in the frame. Tie the new harness to the string and pull it back through—this saves hours of fishing wires through the tight internal frame sections.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,1,0\"\u003e\u003cb data-path-to-node=\"6,1,0\" data-index-in-node=\"0\"\u003eGrounding is Key:\u003c\/b\u003e Honda CT90s rely heavily on a clean frame ground. Use a small piece of sandpaper to remove any paint or rust where the main ground eyelet (green wire) bolts to the frame. A \"floating ground\" is the #1 cause of blown bulbs.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,2,0\"\u003e\u003cb data-path-to-node=\"6,2,0\" data-index-in-node=\"0\"\u003eDielectric Grease:\u003c\/b\u003e Apply a small dab of dielectric grease to every bullet and multi-pin connector.
