Does anyone know any reason for bridging 20 of the wires on the MAP sensor suppressor on OFAB FRST? Was already like it on the loom I have, only think I can think of is that it may be for running a 3 bar sensor and loads of boost (I'm running standard OFAB MAP for now so can I connect it back up as it should be?)

Ran through all my wiring today with a multimeter one by one using Rab's EFI diagrams which I know many have used and this was all I noticed not right.

This is supposedly how it sould be



I have the left most two (on the box itself) bridged. So the loom wires on the plug do go to the ECU pins they should but are no longer connected to the suppressor and the pins on the suppressor are instead bridged.

Hope that makes sense. Car starts but misses and runs like a nail, just trying to rule things out.
