Crossfire help

So I purchased a second Radeon HD 6770 and its working fine as a stand alone gpu, so I bought a crossfire bridge from OCUK 2 days ago and it turned up this morning and I set about trying to install the second GPU and the crossfire bridge... and that's where I encounter a problem, there is a crossfire connector on the old GPU (the one that I built the PC with) but the second one does not have one, how can I install the crossfire bridge without a connector, or is it even nessisary, seeing as one has a connector and the other does not.
