	[* 9] There are two versions of the PSU wires, make sure you identify which are the positive and the negative wires. This is extremely *IMPORTANT*.
-	[* 5] Both wires on each pair are black, the*POSITIVE WIRE* is marked with a *RED LINE* along its length.
+	[* 5] Both wires on each pair are black, the *POSITIVE WIRE* is marked with a *RED LINE* along its length.
	[* 6] For each pair there is a red and a black wire. The *POSITIVE WIRE* is *FULLY RED* (you might still see a little black line).
	[* 9] The wire terminals must be oriented correctly when you connect them to the board. The *2nd image shows the CORRECT* orientation. The 3rd image shows the wrong orientation.
