This video will let you know how to obtain the radio code for the Volvo SC-series radios. If you call the dealer and they refuse to give it to you (or don't know how) contact another dealer in another area. If you pull a radio from a car in a salvage yard, pull the door vin sticker to help you get the code.
Making the world better, one answer at a time. The thing under your tongue is classifed as the frenulum (fren - yuh - lum). this is a membrane connecting your tongue to the bottom of your mouth and is a thin layer of tissue.
Lay the trailer tongue on top of the 2 by 4 precisely 2 feet (0.61 m) from the scale and 1 foot (0.30 m) from the brick. Read the scale's measured weight. Multiply the weight by 3 (to adjust for the fact that the entire weight of the trailer tongue is not actually on the scale); this is your tongue weight.
