On mine, you have to remove the dash cluster carefully, of course. Yes, the wires are short. (PLEASE remember to disconnect the battery first...). You won't have much room, but the wick area to oil ( I use a light sewing machine oil with a needle-like dispenser on top) is a small hole just above the area where the speedo cable screws into the back of the cluster. It's not real obvious but it should be there.
