if the bulb is burnt out, i kinda janked one together, i took a bulb out of the gauge cluster (had one extra layin around) the little bulbs, and i unfolded the two wires that are folded around the actual bulb. then i pulled the stock bulb out of the holder its in and put my new one through, connected those two little wires and soldered them to where the stock ones were soldered and plugged it in and it worked,, just a thought lol
