R34 Stereo Head Unit Wiring Diagram For Pioneer Deck & Handbrake Bypassing

[det034]

Hey guys,

Just thought I'd make a DIY post for people wanting the correct wiring diagram for connecting a Pioneer head unit ...

Im making this post because I struggled with the general diagram and the colours were not matching correct so if you got Pioneer, your in luck.

Pictures are attached but I wrote it down also:

NOTE: May work for other models but this is specifically for R34 Skyline with a Pioneer Head Unit.

Car: Dark green - Stereo: Yellow

Car: Orange with black strip - Stereo: Red

Car: Red with blue strip (in image below its yellow.. used to extend it) - Stereo: Orange with white strip

Car: Grey with blue strip - Stereo: Blue with white strip

Car: Orange - Stereo: Purple

Car: Black with pink strip - Stereo: Purple with black strip

Car: Pale green - Stereo: Green

Car: Black with yellow strip - Stereo: Green with black strip

Car: Brown - Stereo: Grey

Car: Brown with white strip - Stereo: Grey with black strip

Car: Blue with white strip - Stereo: White

Car: Blue with yellow strip - Stereo: White with black strip

Hope this helps if you needed it..

Also if you need help with bypassing the handbrake I worked it out too, if its an old model DVD head unit you can just tap the wire labeled handbrake into the ground wire and this will allow you to have the DVD open while driving.

Although if you have bought a new model pioneer head unit, you cant just ground it, it wont work so what you have to do is on the wiring harness that comes with the pioneer head unit, there will be a wire labelled "mute" (this wire is not needed) so remove it without damaging it and you will need to move it to another port on the plug. You will see on the plug where the wires come out that there are two black wires coming out, but there is a empty gap between them.. now insert the mute wire into this port (make sure it clicks in). Now strip the end of the mute wire and tap it into the handbrake wire. Now that the mute and handbrake wire are connected together you can now ground it or tap it into the ground wire. This will then allow you to have the DVD screen on while driving and if it has a GPS you can now input the address without stopping the car and pulling up the handbrake first.

I know the handbrake bypassing sounds complicated if you have the new type but ill be glad to help if you want to ask any questions or need more detail on certain steps.

Very helpful Benny boy.

This should be stickied. This is the only thread you will find showing what the factory R34 stereo wires connect to.

the way i bypassed my clarion dvd player is a switch yeah shonkey but not as bad as not having dvd screen at all, just a wire from the ground to the switch and the handbrake wire off the deck to the switch, in the ashtray and tadaaa you want dvd just flick the switch.

IMO this should really be (for ease for everyone who is doing this):

Car: Dark green - unswitched power (battery)
Car: Orange with black strip - switched power (ignition)
Car: Red with blue strip (in image below its yellow.. used to extend it) - illumination (so when your dash lights come on, the screen dims so it doesn't glare at night)
Car: Grey with blue strip - remote (or antenna?)
Car: Orange - rear right speaker +
Car: Black with pink strip - rear right speaker -
Car: Pale green - rear left speaker +
Car: Black with yellow strip - rear left speaker -
Car: Brown - right front speaker +
Car: Brown with white strip - right front speaker -
Car: Blue with white strip - left front speaker +
Car: Blue with yellow strip - left front speaker -

For the earth you can just put a ring terminal under the bolt on the panel holding the gear shift boot. Easy to access.

Just for anyone who might be wondering, in GT-X models that included the Xanavi GPS/TV Package & Skyline Holographic Sound option from factory, the antenna booster wire is actually red with a white strip. There is still a grey wire with blue strip in the loom, but at this stage I haven't been able to work out what it actually does.

just found out today while hooking up a new head unti into my sedan with holographivc sound - the grey with blue is the amp for the rear speakers. crappy flat sound from the back if the hu remote turn on wire (blue with white stripe) isnt hooked up to that wire, full sound when connected. its the standard nissan amp power on wire
