Now that I am comfortable working with LEDs in engines and structures, doing the work in a more “elegant way” that doesn’t cause spacing problems (under diesel hoods) or present issues with appearance (wires visible in structure lighting) is now a major concern, so looking for the right wire size is important. My quick solution for the ribbon cable wires is to paint them with a red or black sharpie marker. One of my co-workers told me he has a bunch of ribbon cable he can give me in varying wire sizes, so I guess I beat the need to buy online- for a while! Cedarwoodron
