Hoping someone can help with this as I'm having trouble finding matching colours via google. A phone point in the office has been kocked while some furniture was being moved and it's knocked the jack off the wall and pulled the wires out of the punchdown block. I want to punch them back in but don't know the order and as mentioned, can't find anything via google with the same four colours to be certain of getting it right. I have a White, Blue, Red and Black wire. Which goes to which pin on the RJ45 jack?
