1988 T4 Auto 2.5 Petrol Fusebox wiring problems

[ramapom]

Hi all, I hope there are some among you who are familiar with the wiring in these babies, I'm going to need some serious help! I bought my T4 cheap because it doesn't run, apparently other than electrical issues everything else is good so theoretically once I get the wiring right it should get up and go. The original symptom was that the Van woiuld start and drive normally but after a random amount of time it would just die, sometimes it would start again after 10 minutes other times after an hour, after it started again it would runs normally until it repeated the cycle again. The previous owner had it to a mechanic who went broke when he was in the middle of doing the job so the previous own got the Van back in pieces. That doesn't bother me, it'll be easy enough working out how it goes back together, what worries me is that the fusebox has been left dangling with wires hanging loose all over the place. Also, the small loom going into the drivers door has been cut and the end coming from under the dash isn't anywhere to be seen. There's also a medium to large loom that comes into the cabin from the engine bay at the upper most point on the drivers side, the engine bay end goes into the computer (I'm assuming it's the the computer stashed in the inner guard near the battery) This loom has quite a few wires just hanging and I'm wondering if these wires are unused in this model or they need to be connected, the colours are Solid Green, Solid Brown, blue white, white blue, blue white, Green Red, Blue Red, White Red. Blue Yello and Black White.

I'll post some pictures as soon as I work out how to.

Cheers,
