As far as I understood you plan to build ignition with "wasted spark" configuration. What other devices you plan to control on your engine using SECU-3 unit?

Do you know which type your tachometer is? Low voltage or high voltage input? If it is connected to the ignition coil, then it is high-voltage input.

I guess it is low-voltage input.

For wasted spark ignition control and output for tachometer you need SECU-3T unit and 3 BIP373. You will reassign any free SECU-3 unit's output to HALL_OUT and it will output pulses for your tachometer.
IE and FE outputs are high-side and 12V, others are low-side and 5V.

It is a throttle position limit switch. You can use either simple limit switch or TPS.

Correct.

No. There are a lot of wiring diagrams for SECU-3T unit on the our site. Take a look of them http://secu-3.org/wiring-secu-3t/?lang=en If you need, write your own diagram and show us, so we can find possible mistakes.
Also, please read installation manual http://secu-3.org/installation-manual-secu-3t/?lang=en
Our site is fully translated to English.
