I'll try swapping out the extension cables that came with the kit however I've tried NVRAM clear and no luck as well as re-running the post install patches.Make sure your connections to the Bluetooth Wifi Cards are Correct + make sure the antenna connectors were not damaged & insulate any wires that are open and dangling.
Then do an NVRAM clear - reboot - hold down [CMD]+[OPT] + P+R for the time of (4) chimes
Download the latest OC - Then do a OCLP rebuild & Install.
This worked for me.
