My y5 onto y7 mini-me in a 96 EK DX hatch is running good. except for those pesky cel's. I am down to 2, and they are a result of the fact that my hatch did not have a "fuel tank pressure switch" (FTPS) and the HX ecu is looking for one.

Question:
1. do all the tanks have an opening for the FTPS and use a blanking plate- or do I need a whole tank from a 96-00 that came with the sensor? Or...

2. Is the wiring and connector in the loom unused- or do I need to wire it in?

Thanks!
