    You can use a molex connector.

    There's a real easy way to connect extra wires to a molex, and it looks like it was made that way. Remind me to do a how-to sometime.

    nice guide thanks for that going to go play later as long as i find the LED's i want

    just a question though, why put the resistor at the negative end? a few of the wiring diagrams put it at the begining and some put it at the end.

    Thanks
    Jim

    When wiring an LED you have three options:
    1.wire each LED single with its own resistor
    2.wire multiple LED's in Series with a single resistor
    3.wire multiple LED's in Parallel with a single resistor

    Your current-limiting resistor can be connected to either
    the positive or negative side of the LED, it doesn't matter.

    What matters is the direction of current flow, since an LED is a type of diode, and for a diode to conduct, it must be forward biased. This means that the positive voltage must be connected to the anode, and the negative to the cathode the shorter lead.

    Thanks for the response,
    I've already read that tutorial, i just wondered why people had done it differently i personally would have thought it would have gone at the front before the diodes.

    I must admit im unsure where to go at current as i was tempted to run 2 series of 4 in parallel, though im not sure.

    I think running them in parrallel would be better but wasnt sure.
    i have 8 Red 2.5 volt LEDs which would run at 20mA.
    the way i saw it was 1 of 3 ways.
    * 2 series of 4 LEDs in parallel with a 120 ohm resistor at 1/4w on each series.
    * 1 parallel circuit with a 68ohm resistor at 2w at the beginning of the series.
    * 1 parallel with a resistor on each LED however i have no idea how to work out what ohm / w i need for that.

    anyone got any golden advise on which way i should potentially go.
