Hi guys, can anyone please advise tapoffs for coolant lines? I used both pipes which go to the heater matrix and I only have warm coolant when heater is set to hot on full blast.

You need to tap the heater circuit pipes that run to/from the engine, no good tapping pipes that connect to the matrix(s) because there are water flow control solenoids between the engine and the matrix(s).
