Questions regarding wiring instructions for RR and a mazda cx5

Post by twistedme »

Question regarding wiring instructions for Mazda cx5 1st generations.

I think the below is correct but please respond if it is not. I also have several questions that if answered will help mw with this installation.

Step 1>
Connect RR A connector pin:
07 Brown/Red wire >> to OBD reader port pin 6 wire spliced so pin6 still works with shop OBD reader
08 Brown/Yellow wire >> to OBD reader port pin 14 wire spliced directly spliced so pin6 still works with shop OBD reader

Question 1>I posted in separate post asking if these could be connected at stock or aftermarket harness on pin 10 and 1Q which is labeld can_h and can_L?
Step2>
Connect RR A connector pin:
01 Purple/Red SWI circuit 1 input >> wire spliced to stock (not 70-7903) side of HU wire harness PIN 1N.
03 Pink/Red SWI circuit 2 input >> wire spliced to stock (not 70-7903) side of HU wire harness PIN 1H.
18 Black/White SWI Ground Feed (-) Output >> wire spliced to stock (not 70-7903) side of HU wire harness PIN 1H.
Question 2>could these be wired to the aftermarket harness like 70-7903 at these pins if additional wire and pin are added or do these need to be wired and spliced to the vehicle side of this cable?
Step 3
Connect RR A connector pin:
14 Gray/Yellow-Super data circuit 2 Radio VSS(if equipped) > pioneer harness Pin 15 Yellow 12+
Gray/Red Radio Super data circuit 1 Accessory wire > pioneer harness ?

Question 3> would it work connected to (green)parking brake wire or (purple) reverse gear? none? On pioneer 16 pin cable?

Connect RR G connector pin:
02 Yellow Radio Battery (+) wire > pioneer harness Pin 15 Yellow 12+
01 Black Radio Ground wire > pioneer harness Pin 16 Black Ground

Qusetion4>should these be also connected to aftermarket harness same color wires?

The pioneer harness has the following labeled cables not hooked up:
Pin 09 Green Parking brake?
Pin 10 Yellow/black Mute?
Pin 11 Orange/white + illumination?
Pin 12 blue/white labeled system remote control?
pin 13 Red wire 12 volt Accessory?
pin 14 purple/white wire labeled Reverse gear signal input?
Question 5> should any of these also be hooked up to either the aftermarket harness or the datalink connector A?
The aftermarket 70-7903 harness has the following wires not hooked up:
Pin 1B labeled +B Yellow 12-volt constant.
Pin 1E labeled TNS + Orange Illumination.
Pin 1W labeled Power Ground Black Chassis Ground.
PIN 1R ACC Red- 12 volts switched power.
Pin 1J Blue/white wire amplifier turn on labeled Amplifier control *1.
Pin 1H Blue power antenna labeled Steering switch.
Question6> should these be connected to the head units 16 pin connector and or the maestro connector A?

08 Brown/Yellow wire >> to OBD reader port pin 14 wire spliced directly spliced so pin6 still works with shop OBD reader Correct, when the scan tool is plugged in the RR will stop reading on the lines thus giving priority to the scan tool

Question 1>I posted in separate post asking if these could be connected at stock or aftermarket harness on pin 10 and 1Q which is labeld can_h and can_L? No you must go to the OBD2
Step2>
Connect RR A connector pin:
01 Purple/Red SWI circuit 1 input >> wire spliced to stock (not 70-7903) side of HU wire harness PIN 1N.
03 Pink/Red SWI circuit 2 input >> wire spliced to stock (not 70-7903) side of HU wire harness PIN 1H.
18 Black/White SWI Ground Feed (-) Output >> wire spliced to stock (not 70-7903) side of HU wire harness PIN 1H.
Question 2>could these be wired to the aftermarket harness like 70-7903 at these pins if additional wire and pin are added or do these need to be wired and spliced to the vehicle side of this cable? Yes if you can pin those locations that would work
Step 3
Connect RR A connector pin:
14 Gray/Yellow-Super data circuit 2 Radio VSS(if equipped) > pioneer harness Pin 15 Yellow 12+
Gray/Red Radio Super data circuit 1 Accessory wire > pioneer harness ?

Question 3> would it work connected to (green)parking brake wire or (purple) reverse gear? none? On pioneer 16 pin cable? No you will need to connect these to the factory wiring in the vehicle. Remember red in our harness is not used and grey/red goes the accessory wire of the vehicle with the red wire of radio

Connect RR G connector pin:
02 Yellow Radio Battery (+) wire > pioneer harness Pin 15 Yellow 12+
01 Black Radio Ground wire > pioneer harness Pin 16 Black Ground

Qusetion4>should these be also connected to aftermarket harness same color wires?Yes along with the grey/red as I mentioned above

The pioneer harness has the following labeled cables not hooked up:
Pin 09 Green Parking brake?
Pin 10 Yellow/black Mute?
Pin 11 Orange/white + illumination?
Pin 12 blue/white labeled system remote control?
pin 13 Red wire 12 volt Accessory?
pin 14 purple/white wire labeled Reverse gear signal input?
Question 5> should any of these also be hooked up to either the aftermarket harness or the datalink connector A?No in your application these are not going to do anything
The aftermarket 70-7903 harness has the following wires not hooked up:
Pin 1B labeled +B Yellow 12-volt constant.
Pin 1E labeled TNS + Orange Illumination.
Pin 1W labeled Power Ground Black Chassis Ground.
PIN 1R ACC Red- 12 volts switched power.
Pin 1J Blue/white wire amplifier turn on labeled Amplifier control *1.
Pin 1H Blue power antenna labeled Steering switch.
Question6> should these be connected to the head units 16 pin connector and or the maestro connector A?
They get connected to the headunits wires

Hello Justin,

I have advanced a bit since my first post. I think I will give tech support a quick call to confirm this over the phone if possible but also figured it would reply here so others can benefit from the response also.

In step 3 of my custom instructions it says to:

Connect G Pin1 Black Ground >to> Radio Ground (-)wire.
Connect G Pin2 red no where DON NOT USE!
Connect G Pin3 Yellow 12 volt >to> Radio Battery(+) wire.
Connect A Pin13 Grey/Red-super data circuit 1 >to Radio accessory wire.
Connect A Pin14 Grey/yellow-super data circuit 2 >to Radio VSS (if equipped)

This makes it look like I am to wire these 5 cables directly to the radio harness and not also the vehicle harness.

Looking over the forums and even other custom (maestro generated) install docs some show this but then also show the wires continue to the vehicle side.

from your above response and others asking about these wires I have seen responses that say to do both but I think that's incorrect?

Can we confirm that the correct setup is:
Connect G Pin1 Black Ground >to>(radio and Vehicle harnesses) Radio Ground (-)wire.
Connect G Pin2 red no where DON NOT USE!
Connect G Pin3 Yellow 12 volt >to>(radio and Vehicle harnesses) Radio Battery(+) wire.
Connect A Pin13 Grey/Red-super data circuit 1 >to(radio and Vehicle harnesses) Radio accessory wire.
Connect A Pin14 Grey/yellow-super data circuit 2 >(radio and Vehicle harnesses)to Radio VSS (if equipped)
I Found pin 1Ilabeled VSS so I wired this directly to it I do not see a matching cable on the pioneer harness hoping this is okay.

I also wired in a parking brake bypass which I wired as:

Bypass wires out:
Green wire connected to Green parking brake on Radio harness only
(NOT connected to vehicle side)

Blue wire connected to both radio and vehicle harness with radio Blue/white amp/power ant/ system remote control and Vehicle harnesses blue white labeled amp control*1 Pin 1J.

Black wire connected to Black ground at radio and vehicle harness which is also connected to RR G connector pin1 black ground.


My current harness is wired connected to both radio and vehicle harnesses where I though it is required please answer the above and I can undo it before installing.

I am left with just 2 pioneer harness wires not connected to anything and all wires are connected on the vehicle harness to wires that match on the radio harness that were a concern from my last post:
reverse gear signal purple
yellow/black mute wires not connected to a corresponding on the vehicle harness.

Thanks for your help with this also.
