You should check the rating on those connectors. For the thermistor it doesn't matter, but for the heater it needs to take 25W @ 12V (or 40W @ 12V if your cartridge has all-red wires instead of blue). It'll melt if it can't sustain that load.

I do have a workbench.
So you mean use as much of the wire in the existing harness as I can, and attach the E3D to it directly. Don't use the red and black wire supplied, and hook the thermistor directly to the wiring harness?

Once again, thanks to the people posting for your help.

Some boards vary...some use screw terminals and others require plugs. But if you are using a Workbench with a stock board, which would be a Printrboard, you will want to cut the old wires a few inches away from the plug, slip on some heatshrink, then solder the wires and seal with the shrink.

There is no polarity for the heater or thermistor.

Once all the wiring is complete and you wish to insert plug-in connectors, then do it farther up the line.  The wiring directly around the finished and mounted hot end should be secured with zip ties to limit movement of the connections.

Filastruder is one of those authorized dealers and you can rest assured you are getting the real deal, and elmoret is a good guy to deal with. smile

http://www.thingiverse.com/thing:805681

Which model of the E3D V6 should I buy?

Where is a good place to buy it. I see prices all over the place from $20 to $80
