Can I send 5V power through a serial cable pins ..... (not wires)
unclet:
Hey .... what do you mean "split the load and run it through two or three pins"?
Do I split one RED wire coming from the power supply into three wires and the solder each of these three wires to a different pin?
OR
Do you mean I should take one RED wire from the power supply and solder this one wire to three pins at one time (ie: using enough solder to cover three pins at once?
OR
(something else)?

I would solder two wires to the power supply wire then solder each to a dedicated pin. You could use a solid lead from a diode or resistor to bridge the pins together as well, either way will split the load.

I am not electrically inclined so I have no idea where to get a" solid lead from a diode" or what exact resistor to use .....
BTW: All of the LEDs I bought to connect to the LEDWiz hardware already have resistors (which came with them) connected.

I just meant to take a piece of the solid wire off of a resistor to use as a bridge. :)

Hmmm, I may have come across a sticking point.
Im using three LED Wiz's in my project. I was going to connect the first one using four 9 pin d subs. I was going to connect the cathodes from LED 1 to 8 using the first 8 pins of one of the d sub and then use the 9th pin to connect the common annodes, I guess this will be too much to send through the 9th pin? (LED's 9-32 was going to be connected similarly though the other three 9-pin d subs)
From what you guys are saying I could use 15 pin d subs instead and then bridge two or three of the spare pins to share the load from the common annodes?
Im using 18-19 (0.75mm^2) gauge wire if that makes a difference.
