What is Bluewire?
To extensively modify an electronic device to perform something it was not originally designed to do, usually using blue wire-wrap wire and external components that were not an original part of the equipment being modified. The result is often overtly ugly and has the appearance of being an afterthought.
The need to bluewire a solution is usually in response to a salesperson providing a marginally-performing, lower-cost item for a specific purpose it was not intended to perform, but marking up the cost to a par with a higher-cost item so that a sales margin could be met.
The transmitter did not work as the customer expeced, so the service technician had to bluewire it so it could do what was needed.
