For a number of reasons, my assembly stopped a little .... and all these holidays and all that ...) But the process, albeit more slowly, is still going on. In order not to waste time at all, I decided to do wiring - this does not require a lot of money, but it requires a lot of time. I like to tinker with wiring), so I decided to take it thoroughly. As long as there is free access to all connectors and wires, I will do what I haven’t done before, finish what I haven’t done before, and redo what I did before! )) In general - a complete revision and upgrade. For a long time I have had such an idea - to use all the connectors in the wiring - "full" should be everywhere! )) I have been doing this for several weeks now on quiet winter evenings. I have not yet reached the final result, but there is already an intermediate one. Therefore, the wiring will be a "miniseries" in several parts. So, part one - Body wiring.
The wiring has been lying in a cardboard box in a "ball" for the third year already, and it is obvious that in order to work with it, it needs to be untangled and laid out. There is no room for this in the garage. I wanted to lay it out in the workshop on the floor, but there is sand. He spread the film and began to lay it out. But then even I thought that it would drag on for more than one day, and during this time you need to walk here - someone will definitely trample some kind of connector. And I got a great idea - to make a special stand! ) For this, the old chain-link mesh was perfect - and it was just enough in length.

By the way, my help dog spends these winter evenings in the garage with me)))
I unraveled and hung out the body wiring, including the wiring for the power windows and the central lock.


I examined it, and came to the conclusion that it was necessary to unwind it all, inspect it and rewind it, because even though it all worked, in some places the condition was far from ideal. For example, wiring to the fuel pump:

Power window wiring with some incomprehensible knots and bows.

The long-suffering connector of the driver's door with twists and jumpers:

The passenger door connector seems to look a little better.

The wiring under the dashboard I initially was laid wrong. I already tried to shift it correctly, but it did not quite work out as it should. Now I'll fix it.

The front end with headlight connectors also looked sad. A few years ago I already rewound them with "Soviet" rag tape, but it "mummified")) It dried up, stuck with mud, and began to break like brushwood.


I started to unwind - it turned out to be more difficult than I thought. In some places anticorrosive and bitumen glued the electrical tape tightly, in some places there were all sorts of "collective farm" electrical tapes, of various colors and types, which were very poorly unwound. The most severe turned out to be green - I had to cut it off. There was a lot of glue, anticorrosive and dirt on the wiring, so I washed all the wires and connectors with white spirit with a toothbrush, then washed the connectors with white spirit from the compressor. Here is the tool - a scalpel, a spatula, a toothbrush and a lot of white spirit. And the result is half a box of scraps of electrical tape, and clean, bare wiring.

And then I freaked out even more! If the rear part of the wiring was in quite good condition, then its front engine compartment is a horror - twisting on twisting ... When I put restyled headlights, I cut off the old connectors and "pinned" the connectors from restyling. And now I was surprised that there were already twists a little higher along the braid - someone changed the connectors before me ... in the end - a bunch of twists. We will remove all this and bring it back to normal.


The left door connector will most likely need to be changed completely.


For that right after washing, almost like new.

And connectors C302, C103, C101 are planned to be stuffed to "full"! ;)


Bought the necessary tools and materials.

I bought Tesa electrical tape - in the original it is exactly like this, but when ordering from officials it costs 4 times more. I took 5 skeins of fabric, 2 lavsan, and 1 PVC. Fabric - for the interior, lavsan - for the engine compartment, trunk and external wiring, PVC - for isolating twists and fixing branches - it is the most sticky.
I bought two types of heat shrink - regular and glued. On glue it is more rigid and airtight - I used it on the branches of the bundles, soldered only the edges.
Thanks to a colleague on the E30, I stocked up with donor pieces of wiring and connectors. I also still have my own stocks.

I did what should have been done a long time ago - I printed out the complete ETM for my wiring in '86, and just in case for '89 - it's much more convenient than separate sheets.

Well, and away we go! )) Light creative mess in the process )

My wall-mounted semi-hood was very useful - a convenient magnetic board)

At the moment, the front (engine compartment) and rear (salon and trunk) part of the body wiring is already ready. Nearly all connectors have been replaced on the front, unnecessary twists have been removed, the rest have been crimped and insulated. I made an extension cord on the factory connectors for the antifreeze level sensor, since the tank is in my radiator. All harnesses are rewound with lavsan tape.



At the back, everything was much simpler - I replaced the connectors with number plate lights, and removed the "collective farm" corrugations from the pump harness. I rewound the trunk harness with lavsan tape, and the interior part with fabric.

For the first part, I think enough. Next time - about upgrades in the middle part of the body wiring.
