R34 Stereo Install Questions

[Macross]

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?

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? Usualy runs from the gearbox to the boot

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) 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.

just stumbled on 2 this might help

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.)

Chris - Jut wondering, wheres the amp for that setup? not sure if mine is the holographic sound system as ive got an aftermarket h/u (from japan) but might replace it soon... so id rather know whats happening back there

[Chris Rogers]

it will be ON the rear speakers. fronts should be ok though

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:

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)
