Hi all, I'm trying to install a new satnav head unit into my car, but have a few issues that are cropping up and hoping the guru's here could help me out.

Firstly, where can I find the reversing lamp wire for the reverse gear input? Is it located on the passenger side or drivers side footwells?

Secondly, when connecting the speed sensor input, the manual doesn't specify what sort of signal is required and the ecu signal is different from the dash speedo signal, which one do I use? Would either one cause issues?

Lastly, I wired everything else up and went to test the system, no issues other than there is no sound coming through the speakers... before I go ripping apart all the soldering that's been done, there are a couple things that I thought might have caused the issue. I'm not 100% sure the grounding point I used (I used the metal bracketing behind the dash), is there a better place to use a ground point or would this even be the trouble with this? The head unit also has no input for "Amplifier on" in the wiring harness, so I blanked out that wire coming from the aerpro harness. I'm guessing this is the most likely cause of the problem, but I've scoured the device manual and it has no mention of any wiring to connect this particular wire to.

Anyone able to give some advice on these?

I'm not 100% sure the grounding point I used (I used the metal bracketing behind the dash) OK in my 33 but test with a multimeter, is there a better place to use a ground point or would this even be the trouble with this? The head unit also has no input think you mean output here, use antenna triger instead for "Amplifier on" in the wiring harness, so I blanked out that wire coming from the aerpro harness. I'm guessing this is the most likely cause of the problem, but I've scoured the device manual and it has no mention of any wiring to connect this particular wire to.

that will do part of it. the rev wire is on the drivers side. as for no sound - if its an R34 and you have the holographic sound system - its AMPLIFIED! now hopefully you DID NOT butcher the harness. if so you haev screwed yourself. (I know the positions but not the wiring.)

Cheers :down:

Any idea if the wire in the cabin or under the car?

The satnav is a AVIC-F900BT

Whoops I meant output. Bit more info about what's on the harness below:

just stumbled on 2 this might help

Linky bit

I did have a look at this but was unsure with how to pull the fusebox out, so wanted to check if there was another method. Will take a gander around the rev wire to see what I can swing.

Definately haven't butchered the wiring harness as anything I was unsure about I simply used some shrink wrap to cap off the end of the wire. Stupidly, I just realised my mistake, when I was wiring up the harness everything matched up perfectly, except for the amplifier on wire (which I mentioned I capped off) however there is a second harness (with rca plugs) that has a "system remote control" wire, which I can now see is used to power up the amp, so I can see where to connect that wire to now.

Cheers for the help all :)

there doesn't seem 2 be much solid info on these satnavz, seem to have lots of begs though

given that the speed wire is a signal rather than power I'd expect less that 100mA current flow,

therefore you should be safe if you put a 100mA or similar fuse inline with the speed sig (I'd start with the ecu signal - easy access)

      R34 RB20DE NEO + T ONLY

      By GTSBoy · Posted

      See my post here If you put the Haltech in, you won't have to worry about any of that. And, in case you're worrying about my lack of credentials in doing your exact swap, I put a Neo in an R32. There has never been a stock boost solenoid near my car and the Neo's ECU has never cared. Nor should it, because it is electronically impossible for it to care.

      That's 100% wrong. Did you wire in the boost sensor? If you did not, then that is 101% your answer. Neo ECUs do suck a bit.

      R34 RB20DE NEO + T ONLY

      By Sxnjeet · Posted

      Hello, I'm trying to make this thread basically the thread with all the answers to common questions regarding specifically the RB20 DE NEO + T engine, that comes in the R34. Answers will and only should be provided by those who have done this conversion or actually have some relevant real life experience please. Please feel free to ask questions in the comments if you have any so other members can answer. I feel like this thread is really needed, especially with more Americans buying (unknowingly going to regret it too) rb20 neo r34s. My first question being - What do you guys use for tuning? I have purchased a haltech elite 2500 Plug and play kit for the rb25det NEO because the ecu plug is the same, but I am unsure if any of the pins would need to be repined to match. Second question that I see asked very often - After this conversion, did you install the boost solenoid/ actuator? I see many people doing a + T setup on their rb20 NEOs while running stock RB25DET NEO ECUs with no tune. I am wondering how they are going about doing that and consistently abusing the car because many of these people have had these untuned setups running for a very long time. That was my original plan, but my engine cuts out at 5 psi of boost using the stock ecu with no tune and no boost solenoid/actuator.

      interesting. ive read and heard otherwise over the past year. ive been doing this +t conversion on a rb20 neo using all oem rb25det neo parts including the ECU, and im having engine cut out issues when I hit around 5 psi of boost. Everywhere/everyone ive asked has told me its because I never wired in a boost solenoid/actuator to the ecu, so the ecu isn't getting the right signal once it hits 5 psi of boost, causing the engine to get shut off.
