Electrical advice

[SamD]

Hi all,
Been working on the van today and i know the wiring under the seat is mainly OEM stuff but the previous owners have cut off a power wire and also ran a relay which also goes over to the sterling charger but it then looks like theyve spliced the sterling into a wire on the BCM.
Does any one have any ideas?

Cheers



Its the blue/yellow wire.

these bits are non-standard, (yellow)

the relay is powering something . . . but you cant see what from those pics.

what wire is in the black tubes, and where are they going?

rear LED lights?

a few more pics will help.


what spec is the van?

The fat red cable may be the OEMfeed to the main fusebox under the battery?

 

[SamD]

The relay goes round to a USB plug that powers the dash cam but it also goes to the sterling charger which is where that conduit goes right and dash cam is left.

But where the relay is, thats where a thick red cable is taped up.

its a 2017 T32 Kombi. Its had a previous fit out before we got it and they had the sterling charger, an invertor and a leisure battery fitted. All the left was the charger.

Wheres the charger?

Got a pic of that?

I do but its unplugged now, i have this on the other side where i think it goes to the BCM?

... spliced the sterling into a wire on the BCM ...

Sounds like the ignition or engine running signal.

Sounds like the ignition or engine running signal.

sounds the most logical explanation.

What color wire is it conected to??

What color wire is it conected to??

Didn't know you had American tendencies

 

[Dellmassive]

Fingers and thumbs . . . . . I best turn on spellchecker again.

 

[SamD]

What color wire is it conected to??

Its connected to the black/purple on the ccm.


and then that blue/yellow wire goes to the charger

Middle slot on this green plug, which according to the manual is ignition switch.

 

[Dellmassive]

what pin number is that on the red plug? - you say its a purple / black?

it looks like you have two blue/yellow wires there?

im building a list of that connector:


.

T17-P RED connector under seat:
T17p 17-pin connector, red, under seat on front left



1
2 - or/brn
3 - or/grn
4 - vil
5 - grn
6 - blk/blu - res heat relay
7 - rd/blu -
8 - brn
9 - or/br can?
10 - or/blk can?
11
12
13
14
15
16
17 - rd/yel

Its the blue/yellow wire.

Looks more like a towbar module rather than bcm to me

Ahh you may be right as it does have a towbar ! I think its the CCM though usually under the seat? Well it was on my old T5, mixed the CCM and BCM up last night
