Mystery wire

[Greenmachine96]

I'm still having issues with roof and some wiring that's been done. Got the wiring diagrams and can follow them, but there is a connector, under the steering wheel carrying from the A pillar a green wire and a white wire. The connector simply is an extension so that the colours follow through. And after that I cannot see where the green wire should go to, even though I know it carries power to the Aft controller. On mine it was shoved into the back of the fuse box in a really nasty way. I have found x13 which also looks like it's been doctored in some way, so I'm hoping for confirmation to that the green wire goes in there.

Any thoughts or pictures? Will upload some pics

Up is into the A pillar loom. Down?? The white wire I believe goes to the dashboard loom. The blue connector in the picture carries a pink wire which I believe should go to the sound module.

But again, these three wires were just jammed into the back of the fusebox.

Can't see that style of connector with just a Green and a White wire anywhere in the vehicle! Are you sure there is no stripe not visible in the photo to either wire ?
Green on its own tends to be the;

Air conditioning - Rear Heater & Manual A/C Control System - WL-T, FE-E, J5-DE

Thanks Geoff. I definitely had this wire in my other bongo (recently scrapped). And it has that foam outer. So definitely OEM. The green wire is the thick one in the loom running down the A pillar to power the AFT. There's continuity between it and the green power wire in the roof open/closed switch, so I'm sure it's just the AFT power. But I can't get the roof to power even if I apply power to it directly.

Ah yes 1996, I tend to look under 1997+ version!
There is the connector M2-04, they removed it in later versions, its now in the main loom!

[Greenmachine96]

I may be looking at the wrong wiring diagram then!! Is it the earliest one?

[g8dhe]

Yes in the 1995-5 to 1997-11 versions, the earliest diagrams. I scanned and loaded the first 3 manuals, but the very last one that Ian had 1999-9 they changed the entire format and totally revamped what was on each page, I gave up at that point as it meant starting from scratch again rather than just amendments to individual pages. Also it was only the 1997-11+ version I translated most of the Japanese symbols!

[Greenmachine96]

Think I might have a problem as I seem to have a blend of the wiring. my green wire from the fuse box goes into a loom and then into an x13 connector (from the later wiring diagram).

Is it possible this van has had the AFT added, but a pre 97 version on a 98reg vehicle? Anyway to check it has AFT as standard?

[g8dhe]

I have always suspected that the changeovers from one manual to the next were never as exactly matched on the production line! I suspect they continued to use old looms and things until they ran out and switched what was on the given line (there were most likely more than one lines as well!) so the main loom connectors also switched from X0-3 to X0-14 etc. in this instance. It ought to match one or the other, but even that can't be certain as there are various options that entailed changes to the main looms as well which most likely also applied to the AFT/Sunroof/Tintop | Diesel/2l/V6 options as well!
I doubt that they would have modified the TinTop to AFT in the factory, as the actual roof is double skinned on the AFT version and not on the TinTop, I've only seen one person do that, they cut off the entire roof below the pillar tops and then welded an AFT roof to the pillar tops, but they then realised that the wiring didn't match up!!!!

[Greenmachine96]

Ok. That's useful. So I might have to have a good think about how to get this sorted. Fyi this is based on a previous thread of mine where someone had cut and modified a few wires to make the AFT run direct off the main (and only) batterywith engine off. I'm just trying to put it back how it ought to be and I suspect they managed to bypass the "brake on" bit, as without the engine on I assume it wouldn't send that signal.

[g8dhe]

Actually the Handbrake on signal is just an Earth from the brake switch, so that signal would continue to work its pulled up by the supply via the lamps themselves.
