yes you can either use the orange/dark blue OR dark green/red.

It's better to use the MAP signal dark green/red.

wire it just like the diagram shows, and solder all connections.

does it matter if you take the white and gray wire from the SAFC and put them together it the green/red on the ecu ??? im having a problem with mine and a P0108 code... i just took the wiring off the green/red wire that was coming from the SAFC.. and now my car runs normal again... any help would be appreciated..

The grey and white wires need to be soldered inline in different locations. One wire is ahead of the other so that it can see what the pcm sees and the other is there to alter what the pcm sees. If the pcm is seeing the alterations as they are happening, it's going to throw a code. In your case, it would be P0108

Hey guys, im running Stage 0 with Stage 2 injectors stock turbo at the moment, I just got my safc installed, i havent touched the settings yet and im running 100% default setup because i dont want to no adjustments until my AEM uego air/fuel is connected. On idle the engine is very unstable.. drops rpm like its camming, seems to be ok on throttle and boosting but it backfires alot when im off throttle.. Is it ok to drive the car on default safc setup or is there a basic setup for our engine so it runs safe ? noob questions 4tw this is completely new to me

sell the stage 2 injectors for stage 1's. and yes, it will be ok to drive, but if you can swap the stock ones back in for the time being.
you will not need stage 2 injectors no matter what mods you have with a stock turbo. sell em, get some money back, use the money for other parts

thanks.. well the engine is fuel cutting like shit when i push the throttle to 20-30% and backfires alot, running way to rich right ?

Can you guys give me a advice what settings i should change to lean it out ?
finishing to install the UEGO tonight so i can do some adjustments safely

you cant hit fuel cut without going into boost,, which is something you should never be able to do with a big turbo and at 20-30% throttle.
its backfiring cuz its running so rich and the PCM is not calibrated to run that large of injectors.
now you might see why its worth the wait to do everything at once so that it all works together..

Here's a question fer ya guys. Why is it that we have to set the correction to 15%? Why can't we go 30 or 60??? This Q is for the NEO.
