Hi all,

Im putting in a new head unit in my brothers Volvo haha V40. Went with entry level alpine unit with hi-speed ipod control from Tonkins (cheers Ben :) )

The old unit didnt have a constant power to it just to acc powers and 2 grounds (WTF stupid germans). Where will be the easiest place to steal constant power from? The ciggie lighter is acc aswell :P Im thinking maybe the ignition itself would be the shortest to run a cable and their must be constant power their. Any ideas?

I really CBF running a line direct from the battery and fusing it...

Also the stock headunit controlled all 6 speakers (4 2 ways i think and 2 tweaters) the alpine unit ive hooked up to the 4 speakers is their anyway i can hook up the tweeters aswell without buying more gear cos hes a full on tight ass when it comes to his car. as long as its got fuel and a few empty iced coffee cartons floating in it he's happy :down:

Cheers,

Chris

the car has two grounds????, one is a light switch which shows ground until the lights are turned on, then goes to 12volts if you use a test meter ?

this is a volvo wiring diagram, check your model here

http://www.volvoclub.org.uk/faq/MaintenanceManuals.html

Main radio harness 13-pin connector (for large 14-pin radio connector):

pin 1 (brown/white) left dash speaker (+)

pin 2 (grey/red) right dash speaker (+)

pin 3 (brown) left dash speaker (-)

pin 4 (grey) right dash speaker (-)

pin 6 (yellow/white pair) night dimmer (from headlight switch & relay)

pin 7 (white) dash dimmer (+) (connected to dash lighting rheostat)

pin 8 (blue) dash dimmer (-)

pin 9 (green/red pair) +12v from battery (and to optional CD player)

pin 10 (black pair) chassis ground

pin 11 (orange) +12v from ignition (via fuse 14)

pin 12 (green/grey) power antenna motor control output (switched on/off with radio on/off) or power for in-window antenna amplifier (see note below)

pins 5,13 (not connected)

Speaker harness 13-pin connector (from small 10-pin radio connector):

pin 2 (green/orange) left front door +

pin 6 (orange/black) left front door -

pin 3 (orange/white) right front +

pin 7 (black/orange) right front -

pin 8 (blue/pink) left rear +

pin 12 (brown/pink) left rear -

pin 9 (pink/white) right rear +

pin 13 (pink/black) right rear -

pins 1,4,5,10,11 (not connected)

see it says Chasis ground plack pair?

So i should look for green/red for the constant 12V

What about the illumination/dimmer on the unit what one of those do i use?

mate , use a multimeter to test it, guides can be wrong and I take no responsibility if you fry a radio, set off the airbag, or toast the car computer with a test light.

if your not sure have it installed by a pro installer. what part of town do you live in ? I might be able to test the wires for you time permitting?

Jack 88 on here does mobile installs, pm him

check to see if you have a dash clock, dome light ? I would suss you have a blown fuse off the constant power wire. you dont need to run a wire to the battery on new car?

check the fuses

is there anything else on the dash that doesnt work ? or has anyone hacked up the harness before ?

if all else fails, I would take it somewhere to have it looked at, to cut into the main harness to solder one on is best left to someone who knows what to do, there is a wire in the steering wheel area and possibly elsewhere depending on the year that contains the airbag, ground it out and bang the airbag goes off with your face mm from it.

best of luck, but check the fuses as above , if the car electrical is working properly, you shouldnt have trouble finding constant power near the radio

do not circumvent a fuse,or increase the amp rating .. fix it right or risk fire

      I dunno about that as a blanket statement. Pitwork is Nissan's "Nissan genuine" thing, and for stuff like timing belts, I have found them to be excellent. Of course, for things like oil filters, you always use proper trusted brands anyway, not whatever the OEM has taken to using.

      Ahhhh... If you were putting 12V to the led in there, that's likely made it very unhappy. Chances are how you put power, was 12V across an LED that's meant to only have about 20mA through it at peak, and a forward voltage of about 1.8 to 2.4 volts. That circuit is likely only a 3V3 circuit, and will have a resistor in series with the led too. That's my guesstimate on that light, without having touched one.

      Another vote for installing them and see how you go.  I mean, you already own them, why would you not fit them?

      I have had too many of those over the years, my cars have a toolkit or at minimum a cheapy multi tool thing because its too easy to be snookered by some stupid plastic clip that stops you checking the battery terminal isn't loose.

      Basically, if there is a part# on the nissan catalogue, it is a genuine part. There is a thing called "new old stock" which is stuff made years ago but never sold (or landfilled), but it is super hit and miss what you can buy. Other than some expensive Nismo stuff there is nothing new being made that suits these cars. The only time to be a little careful is (mostly in the US I think, but maybe Japan too), Nissan started rebranding some cheap crap maintenance parts like oil filters as "Pitworks"; stay away from them, if you are buying cheap just buy whatever the local car parts shop carries The three part numbers have an explanation on Amayama: 0V005 is auto, base style 0V015 is manual 0V505 is auto, hectic momo branded ones, maximum F&F points there!
