I'm having trouble getting my wife's BT to get strong signal. I took tcu from 05 e46. I put one of these tcu in my 03 e46 m3, I added antenna and mic. The prewiring was all there including cream fakra connector. Work greats paired easy. So I tried same thing in her 03 x5. I can't find that cream colored fakra conn. I could only find light blue one. I put that in the coded blue terminal on the tcu. Then the pin harness in other end. Also found black fakra with purple clip with male and female together. I unplugged it and attached a BT. Antenna to female end. Left male end hanging there. I was able to pair put signal strength seems good but quality is poor. Do I need to do something with eject box? There's nothing there but a small harness and another male black & purple fakra conn. can u please help? I've checked all forums and can't find anything were a cream colored fakra is missing
