installed well on my '96 tomos st. i think that spot 3 is the positive but i may be wrong. plugged it in opposite and it started smelling funky. didnt realize there was a big bulb in the box and started trippin thinking i only got the amber mood light. dont be fooled. my p26(s) bulb only had about 3 months of use, buy another while you're here
found out the resistor wire broke. I don't like that. my bulbs are popping like corn rn. should just be a solder
