    Hi Kevin

    welcome to the forums :)

    gosh I have pulled many of these out of old gear
    do you have any old sound gear, DVD's, VCR's stuff like that ???

    they are full of that style of connector of varying pin counts.
    I recover many of them for use in other projects
    maybe you can do the same :)

    I don't know where you would find a ready-wired plug. You can probably find the necessary bits at Digikey though. You need to buy the "housing" and the pins separately. The pins normally are connected to the wires using a crimping tool but you can bend or cut off the crimp "wings" and solder directly to the terminal (using minimal solder).

    Here's the main Digikey page for the housings:
    http://www.digikey.com/product-search/en/connectors-interconnects/rectangular-housings/1442556
    Use the table to narrow down your options. Number of positions = 8, number of rows = 1. I'm not sure about many of the other criteria. In the past I've tried choosing options that sound right, and the part I want turns out to be described differently from the choice I made.

    Can you measure the pin spacing? Measure the distance between the centres of the end pins and divide by 7. That will narrow things down even more. Then try to match up the shape and features (bits that slide into grooves or gaps, bits that clip in) between the header on the board (which I assume you have) and the housing options. The crimp pins are separate and you'll need to search for them by description too, or the data for the housing may give you a part number for the matching pins.

    Good luck!

    The problem with Ebay is that you can not guarentee the quality of the parts, you are better going direct to a specialist catalogue distributor like www.farnell.com or using a sourcing website. One I have used is www.oemsecrets.com. If you search by description you should return a number of results which should help you to find the 8 pion plug you require.
