You don't need a diagram because you can look at the back of the PC board and follow where the traces go. Get the shop manual and look up the cluster connector, the pins are all labled.
You don't "bypass" the bulbs and I don't know why you'd want to. If you want them not to work just remove the bulbs and sockets
Or.............are you just trying to test the turn signals with the cluster out? In that case you don't need to bypass anything-----just connect the two ammeter wires together and make sure they are taped "safe"
