ETA dissection and replacement of wiring loom

[doolar]

So this is the original ETA from my 1994 non-ASR E420. I swapped it out a few years back when I learned that the ETA's too have the ecojunk wiring. I also had a problem with a slight surging when using CC, that got remedied when I swapped the ETA. Apart from that, I had no issues whatsoever with this ETA.

Now I thought about rewiring the ETA, so I have a spare unit on the shelf. I had no idea on how the wiring looked inside. As you can see from the pictures the wiring was almost completely free from insulation inside the ETA where it connects to the circuit board.

Next on I was curious on how the wiring looked inside the loom. The loom is still soft and pliable, and I could hear of no cracking when bending the loom. Well, as you can see from the enclosed photos, it's a mess. The tightness of the loom is what keeps some of the insulation in situ, but it is totally shot.

I'll update when the loom arrives. Of course the ETA will be cleaned properly, it's a bit dirty as you can see. I just brake cleaned it before I started to work on it.

Thomas what plug type has your car got? Early Pancake or Late Round smaller plug?

The new looms are only available for the Pancake type plug. Otherwise you have to make a new loom up. As I said I will send you the later type pig tail loom I just removed from the spare ETA I had. It was pro re-wired with non bio wires.

It's late round plug on my car, so the one you send will be perfect! A big big thanks for that Joe!

Excellent Thomas. I plan on doing the same to a spare unit I picked up. Thanks for forging a path
