wiring help C5

Post by civvie »

I hope to fit a proper power supply for the sat-nav to my 52 plate C5 2.2hdi bypassing the wire hanging out of the cigar socket. I intend to use the proper kit from Navman because I am getting feb up with the wire trailing accross the dash.
My question is easy (I hope) as this thing is multiplexed is there any problem in splicing into a live wire, I intend to have the sat-nav on the passenger side and find a feed from around the back of the glove box area. I would like it to be live all the time. Are there any wires that are suitable on the passenger side behind the glove box? Don't want to start drilling holes in the bulkhead to get to the battery think that would be a mine field.

Look forward to any replies

there are a few battery live feeds behind the glovebox area at the fusebox,there should be no problem splicing into them.
if you really wanted to have a direct feed from the battery you dont need to drill holes,there are 4 spare wires already passed through the bulkhead,they are located behind the glovebox & the other end comes out under the fusebox in the engine compartment.

Cant you come off the back of the fag lighter?

You should find a nice live & earth on the back of that.

On the multiplexing issue, Taking the supply for your satnav from the back of the fag lighter is fine, DONT connect it to any of the radio supply wires or anything else, Thats linked into the multiplex system & your BSI unit wont like it :wink:

i think the fag lighter is ignition fed & he wants a battery feed,you would need to use the accesorys socket at the back of the centre console.

Doesn't the C5 have the normal PSA move a fuse in the fuse box to choose the status of the fag lighter feed?

Then again wouldn't the BSI going into Economy Mode if electric's are used for more then 30 minutes after ignition key removal or go to sleep when the cars locked with the key & shut the whole C5 electrical system down anyway?

The C5 is multiplexed, It likes to have a sleep like us humans too :wink:

Don't disturb it by unlocking it & waking it up, Let it dream away peacfully lol

Thanks for the input so far, one of the reasons I am looking for a unswitched supply is, I got fed up with sitting in the car setting the thing up to finda destination, turn the ign on and start the engine, but when the ign switch is turned there is a second or so power cut and then back to resetting the thing.
Also stop to get diesel, turn off the engine. sat-nav turns off. And here we go again.
Will look for the 4 wires behind the glove box, did think of using the power socket between the seats but don't want to strip the car to wire it in.
Yes I am scared of linking into the multiflex system, do'es the wire look the same as "normal wiring"

Yeah, The wires look the same as any PSA car but there are less of them overall.

PSA use black numbers & letters printed on to the coloured insulation of the wires every few inches to help identify them.

If you see 2 wire next to each other, One green & one white then they are the CAN system, One wire is CAN high & the other is CAN low.

I think from memory the green one is CAN low & the white one is CAN high, DON'T connect anything to those, You will upset the BSI unit if you do,

I can assure you that the socket next to the handbrake does not turn off after 30 mins (flat battery from a mini fridge proved that).

Am interested in peterlee's comment about the fuse for the "fag" lighter being switchable, IE off on ign switch off, or on all the time.
Any comments on this?
Oh and the cars out of warrenty and I am now getting the clunk at the back suspension.

Any one got a morris minor for sale, things were easy in those days!! there are times when we could curse advancement.

PSA have before fitted the fuse boxes with a switchable fuse location for the radio & the fag lighter.

I done know if they still do this to the newer cars though, I know the 405 had it, Im sure the 406 also had it.

It used to be in the handbook & it was a case of pull the fuse out & move it up or down & push it back in.

You would have 2 larger slots in the fuse box with 3 holes in them, Depending on how the fuse was installed gave you ignition dependent or constantly powered for radio & fag lighter.

No matter muxed or not - there should still be a permanent live - and a key live - for the radio (both fused) ?
These are usually quite easy to get at.

The dealer said not to take power for the camera detector from the radio power. The car knows and it affects the locks (Jan 06 built Picasso 1.6 HDI)(Nice).

He also said not to hack the cigar lighter, but not sure what happens.

I heard about locking problems on late Xsara if you changed the radio.

I can not see the difference in taking power off the cigar lighter socket - via the socket or via the cable feeding the socket ?
Same goes on the power feeds for the radio (standard connector versus cables feeding these) ?

I'm quite sure the mechanic pointed out and meant it could do haywock (possibly to any circuit in the car) if you did a mistake on which cable you got at - and how big a current drain you took off the cable.

- or he may just have ensured he could make a meal of it at a later date :!:
