New 2DIN radio receiver bezel for Maserati 4200 Coupe/Spider

[Masera]

Good morning, another quick question, in one of your earlier posts on this thread you have a link to a video, I try clicking on it, but it doesn’t work. What was it?

There is a link on page 1 , how to install that show step by step removal of center console, I clicked on it today and not working, I found that video by searching this website or Maseratilife for center console removal, I suggest you do the same if you find it difficult to
remove center console
There is a second link on page 2 that is youtube video tips on crimping, that one still works

Ok, made some progress! Head unit wired, sound through the speakers! I need some help, I am struggling with wiring the hazard switch. I went with the one Sablewolf recommended, it has 6 pins and I am not sure what goes where. Any input is appreciated!

This is kind of easy if you have an ohm meter or a bug light(this thing lights up if you touch both ends of it to gether).
1. To find switch 2 pins in 6 pin device:
with voltmeter on OHM setting ( will read about 0 to few ohms when you touch both probe ends together) connect
one probe (or one end of your bug light) to one of the 6 pins then touch one of the other five pins with other probe
(or other end of bug light) now press the switch if you read about 0 ( or your bug light lighted) you found the 2 ends
of the switch, you wire one to car GND and the other to the hazard switch wire of the white 6pin connector.
If you did not read about zero on your ohm meter or not see bug light lighted you repeat the same process and
connect one end of ohm meter to another pin, note at this time you already eliminated one of the 6 pins and do not
have to press switch and touch five pins you do it only to 4 remaining pins and again you either find the 2 ends of
switch (meaning reading zero or seeing light upon pressing switch) or move to the 3rd pin and repeat touching remaining 3
and so on. the process is very quick as it only takes a second to press and touch.
2. Finding light bulb 2 pins in 6 pin device(if already done above, only 4 pins left to check):
is very similar to above except instead of a voltmeter or bug light you use a small battery, the switch bulb light with
12V but most of them also light with 9V so I used a small 9V battery that is common household item. Note this time
you need not press switch, just connect one end of battery to one pin and quickly touch other pins to the other end of battery
till you see the light on, then connect one pin to GND and other to +12 Switched pin of the white 6 pin connector.
that light will be on when car is on.
3. Even easier is if you ask Sablewolf which 2 pins are for light and what other 2 pins are the switch

Once again, you are the man! Hazard switch figured out!
One last thing, I think... on the step down converter, what do I do with the out (black) wire?

 

[k1coupe]

Short answer, connect to ground.
On the 7.5V step down that I bought both in and out black wires(minus -) were electrically the same as if you use ohm meter it
show zero Ohms between the 2, so you could connect both to GND at same pin or simply ground one and cut the other.
But to be on safe side, it is best to connect both to ground, I did not want to crimp 2 wires to one pin
as it would not be strong crimp , so I crimped the OUT black wire to a pin and insert it into white 6 pin connector GND, then connected the IN black wire to a car chassis hex nut near where I placed the 7.5V step down converter, so both black wires are grounded
and my 6 pin connector is not over crowded by 2 wires crimped to one pin.

Great! Sorry, back to hazard switch. How is your illumination set up? Meaning, is it always illuminated when acc is on, or does it illuminate when you trigger it?

 

[k1coupe]

On mine, the switch is lighted when acc is on ( has nothing to do with switch triggered or not) because I wired one leg of the switch
light bulb to "acc on" pin of the 6 pin connector and grounded the other leg of the switch light bulb.

 

[Masera]

Done! A big thanks to all, especially k1koupe!!! Still need to hook up reverse camera, but I have to tackle some home projects first.

How about the sound thru speakers?
My car NIT Connector B that has 8 wires supposedly should connect to 4 speakers does not seem to be connected to anything (Ohm meter reads open as oppose to 8 Ohm or 4 Ohm that is common for speakers).
So I am wondering if there is anything else is between Connector B and speakers? did not have time to open panels and trace wires yet.
But everything else on radio works fine and I could unplug connector B and connect speaker(s) to my 8 pin mating connector and radio sounds fine. For comparison I do like my bezel with switch and usb port better:

 

[Masera]

Sound is good. I followed your direction and used the 8 pin connector you and plugged it into the connector B that was unplugged from the NIT. At first I got no sound, but then I realized that I needed to bypass the auditorium amp since it is no longer being utilized, meaning I am now going from my head unit, directly to the speakers. I am not sure what question and/or issue you are having?
As for your bezel, I do like it, but I wanted to keep the area not so busy. On another note, why haven't you addressed your buttons?

 

[k1coupe]

What is the auditorium amp? where is it? how did you bypass?, I probably need to do same
Are you talking about NIT below? I took mine out

 

[Masera]

Not all cars came with it, if yours did (you can usually tell by seeing an auditorium logo by front speakers), it is located behind the battery.

Thanks, I bet that is the reason, it seem a lot of work accessing it

 

[Masera]

Not as bad as it looks, I was able to do it without removing the battery ( little tight though). I am surprised you didn’t already know this.

I bought this car in October and did not drive it yet, waiting for snow season to be over to take it out of garage and put it on road, do not even know how to paddle shift.
Do you have to touch paddles if you press auto on gear selector or then it works like regular automatic transmission?
I am going to try trading with a Spyder because I really want convertible for Summers.

 

[Masera]

I would have never of guessed that based on the knowledge you have for the head unit upgrade. I have a 3 pedal and I am not familiar with the paddled cars. There are many threads on here and on ML that can better answer your paddle questions. The one thing I do know is that using auto is not recommended for extended clutch life. Maybe someone better versed in paddled cars can chime in.

 

[k1coupe]

Thanks for mentioning about auto mode, I think paddling up/down should not be an issue since I used to drive manual transmission.
As for ease of doing the head unit upgrade, such tasks are trivial matters to those used to work in electronics.
Found the AMP (auditorium), could only bypass after moving battery out, removed the AMP too as no use it sits there.

It's fine You'll soon get used to it and then wonder if you'll ever go back

When you paddle shift up or down, the foot you press the accelerator pedal suppose to push for rev up or not press so
engine rev down or stay same and you just paddle down or up regardless of accelerator pedal position?
