With jumpers? You have severed a Ribbon, there is no way you are going to be able to jumper a ribbon cable break, what you need to do after a ribbon cable is damaged is locate the part and buy one that is not damaged and then replace it. if the ribbon comes attached to something with no release you will need to bu what ever it is factory mounted to. if both ends have a release you can just replace the cable.
The problem is easier for you than some one that has a internal cable separation since the break is obvious.
check this out and see if it the one you need, if it is Not then locate the one you do need. this one costs 2.60 USD how cheap is that?
