1. Boost solenoids - are you using the Haltech ones? You can wire both of them in parallel to the same output. Use DPO #1 on the main ECU I/O for this. 2. Are you running the GM 4 bar MAP Sensor? Use AVI1 on the main ECUs I/O. 3. Thermo fan - no idea as I am using the clutch fan still. 4. Intake Air Temp - use ATI#1 on the main ECU I/O for this. 5. Fuel Pump - is this a second pump or your main pump? Main fuel pump doesn't need to be wired in as it is controlled via the main EFI harness. 6. EGTs - I drilled and tapped each MSP manifold on the back, just above the turbo flange. There is a nice beefy bossing there.
