As my “Beast” came with the C43 radio it did not have the vehicle harness for the Aux Input which is supported by the BM53 radio. As the next tribute to be paid to the Beast is the BM53 radio, I took the opportunity to build and fit a harness to the vehicle to support the Aux Input facility after the new radio is fitted.
