**SOLVED**
Years back when I bought my intercooler from ZZPerformance - they recommended using a 'pink' wire under the fuse box as the power source.
A few months ago; I replaced the crappy bilge pump with a BOSCH unit.
Well.... the Harness ZZP includes was NOT weather sealed. (no rubber grommet) This caused road salt / spray to corrode the connection, and effectively short out / burn off the pump terminals, and blow the TCC fuse.
I disconnected what was left of the pump harness, and replaced the fuse. All is well. Well - except for the IC pump
