Hey,

Im installing a haltec and aftermarket boost gauge, I am going to re-pin factory map to suit the haltec but I have unplugged the map and boost gauge sensor without realising they have the same plug.

I think the boost gauge wiring splits out from the brake fluid level sensor like I have pictured, and the map sensor splits out along the firewall, but can somebody just confirm I haven't got them arse about

Cheers, e5f57ce314168e0f47116451f7d4eb5c.jpg7d420ed2ec30caeda69ec16bd86f4a25.jpg

Gauge sensor is located on firewall close to booster, so wiring is most likely to be over there.  ECU boost sensor is located at back end of engine, (therefore central on firewall) and so wiring is most likely to be there. So your conclusion appears sound.

My knowledge only really comes from having the Neo in my R32....so my (original R32) gauge sensor is on the driver's side of the booster and the ECU sensor is attached to the bracket that holds the little solenoid behind the TCU motor....but I suspect it is attached to the firewall in an R34.  Either way, it is at the back of my engine.

      V36 2008 Coupe Wiring Differences with Android Screen

      By sausagepianist · Posted

      Hey all, I'm sorry if this has been discussed before.  I have a 2008 Japanese import V36 coupe with nav but without Bose. I bought one of those AliExpress android screens, which for the most part works really well.  The only thing that doesn't work is the air con controls (well sort of) and the factory reverse camera.  The AC can be controlled fine but it doesn't report the change in temp and mode to the screen, and the volume knob/other audio controls from the panel don't register on the learning app.  I am pretty certain that the problem is the difference in the head unit between base model (Nav but no Bose) 2007-2009 coupes and anything after 2009.  Mine is the one with the blue connector all the way to the right as seen in this forum post:  The reason I think this is there is one wire left over that doesn't fit anywhere on this head unit, or in the factory screen which also uses different connectors to more recent versions.  I've seen the upgrade from OWC, and have sent the guy a message on eBay but no response yet.  I also don't particularly need the whole kit, just *maybe* an adapter for this one cable.  Did anyone else here have the same problem, or have any insight about what I can do to get this working?  I have been in contact with the seller but all they seem to be able to do is ask for more pictures and videos. Minor edit to add:  I have been researching and found a screen on Aliexpress that actually specifies my head unit in the listing, so these things do exist.  I will contact the seller to see if the wiring adapters are interchangeable with other screens.   Thanks in advance!
