Boxer 2017 help with D+ wiring

[GWO110]

Hi, I'm really hoping someone can help. I need a D+ signal, either a +12v or D+ to ground. It's a 2017 Boxer 2.0 BlueHDi. I've been searching for days on end online and I've purchased downloaded manuals but still no success. The van does not have the converters sockets in the B-pillar. I read that it's the brown/green wire from pin 25 on the 52 pin lower right connector on the Body Control Module / Dash fuse box. That must have been an earlier model as my connector plug has 60 pins and no brown/green. I read that it's the brown/black wire from the BCM in the Converters manual and I've spliced into three brown/black wires with no success. Can anyone help or has anyone got the pinouts for the 60 pin connector from the BCM/Dash fuse box.

Might be easier to just run a wire direct from the alternator ?

There is a D+ signal available on a CBE 300 panel. But this is of no use to you if you haven't got CBE equipment.
Back to jockaneezer suggestion.

D+ signal is only to say engine is running.
Since you are unlikely to leave ignition on without starting the engine you could use a delay relay that switches, say, 30 secs after ignition on by feeding the delay timer from a feed in fusebox that is live with ignition on.
Selection available on ebay or amazon.

use any ignition live to trigger a smartcom relay use that to trigger the split charge relay , im assuming thats what you want the d plus for? the smartcom is adjustable for trigger voltage set it to above 13v

If you have solar, or indeed a mains charger it may reach 13v without engine running.

Van next door in spain had its aftermarket daylight running lights on with no ignition, voltage sensing relay saw charger voltage as engine voltage high so turned lights on. Admittadly wired direct off battery.

Are you sure that the converters manual shows brown/black as D+ at ground, I thought it showed it as Brown/White , but I may be wrong.

Hi, thanks for the reply but my understanding is that its not a traditional D+ from the alternator. It's a signal that only goes to the Engine control unit. Any D+ (probably to ground) is generated via the Body control unit.

Yes I've got solar and mains charging so the voltage sensing method doesn't work for me.

The latest converters manual I have is the 2016 version which says brown/black but I would love to be corrected if anyone could confirm for the 2017 Boxer 3.

Thanks, I have got CBE DS300 but it again comes down to voltage sensing to operate and since I have solar charging the CBE can assume the alternator is running when it's not. I want the D+ for the CBE DS300 and for the Voltronic B2B.

Can't help with the OP's question, but maybe one of these could be a substitute. It is triggered by engine vibration, not voltage level.

The converters manual in the resources section on this site and another 2016 manual both show the D+ active colours as B/M (Italian) which converts to White/Brown if I am reading it correctly. I do not think you can look at resources but have a look at misterg.org.uk/camper-converters-socket.html/

Chicken and egg!! you are installing the CBE DS300, not all ready installed?

 

[GWO110]

Hi thanks for the reply. I'm confused as I'm looking at a version which appears to be the same as the one in the resources section as I've now paid the subs. I'm looking at page 87, D+ (active at ground) colour MN (Brown /Black). I hope that I'm missing something and that you're right so I have something else to try.

Hi, yes I'm installing the CBE DS300 and solar and B2B

Or just put a thermostat phial on the exhaust manifold, budget option

thats why you use one relay to trigger a second double separation, solar or mains charger shouldnt be putting voltage into the vehicle wiring only the hab wiring its why i dont like vsr's

 

[GeoffnDee]

GWO110 My mistake, it does indeed show M/N in the resources, It is M/B on the Misterg site , which does also state colours can change, but is supposed to be a recent one, have a look as it also has contact page which may be some help.

 

[GWO110]

Thanks to everyone for the input. I'll check to see if there's a M/B wire from the BCM connector and if there is I'll test it. If there is and it works then I'll report back. Otherwise I'll do as Mitzimad suggests and use an ignition live to trigger a smartcom relay and use that as a D+ for the B2B and the DS300.
It does seem hard to believe how difficult it is to find correct wiring diagrams or just connector pinouts for these vehicles though. It would be so simple if we knew which pins on the BCM were used for the various connections in the converters sockets etc.

I've used the method in the video below on a 2017, 2018 and a 2019 Boxer (and a few Relays of the same ages). No guarantee of course, but always worked for me.

PS - When this video was made, the guy in the video built motorhomes for NuVenture.

 

[GWO110]

Yeah thanks, that's where I took the ign+ feed from

 

[mitzimad]

if you come of the battery direct theres no chance of it upsetting any of the modules i just joined to the main relay on the feed side to trigger the smartcom to trigger the main relay theres very little extra wiringjust remember to fuse it all

[GWO110]

So this is where I'm at now, see sketched diagram.
Couldn't find any smartcom relays available but this Maypole Tec3m has the trigger level adjustment so should do. Battery sensing direct to B1 (van), output to N/O contacts in relay triggered by ign+. This connects B1+ to B2B trigger when ignition ON "And" B1 voltage is high.
A N/C relay then turns the B2B (D+) trigger to a D+ Grounded signal for the DS300.
A N/C relay triggered by ign+ disconnects B1 from the DS300 B1 to retain the mains charging to B1 and retain the DS300 D+ functions.
Solar will feed 80% B2 and 20% B1
Two L36-EFB batteries now fitted under the drivers seat frame. These are the lowered seat frames for the swivels in case anyone wonders whether 190mm high batteries will fit into these. Clearance is about 10 - 15mm
If anyone can see any potential issues I'd be pleased to hear.

 

[mitzimad]

i missed the bit regarding you having a battery to battery so you dont need a split charge relay just use the signal from the tc3
