The ST4s that was the source of my engine for my 888 had been dropped on the right side. The main point of contact with terra firma seemed to be the battery, ecu multi plugs and right hand exhaust. The silicon seals were missing along with the lock bar things and the cover from the top connector. The sides of the sockets on the ECU were damaged too. Although the bike was fully intended to be a donor, she wasn't all that badly damaged and out of curiosity, I fixed her up and MoT'd her to see what like a bike the ST was. Quite a fine bike, as it happens, fast, and comfortable with great handling. As a quick fix, I wrapped the damaged plugs and ECU with insulating tape, which I repeated when initially fitting the engine to the 888. Having had a bit of a shakedown with the 888 last year, I'm getting around to tidying up a few unfinished and slightly bodged items. First issue was ecu reflash courtesy of ChrisW to allow me to remove the immobiliser and key antenna, both of which were cable-tied to the left side of the front fairing bracket. Chris had some advice about how to repair my minced ECU, that will be phase 2. I bought a cheap Fiat Punto ECU with the multi plugs still attached. After some experimentation, I was able to remove the individual connectors and then cleaned up the plugs. Tonight I carefully transferred the individual connectors and transferred the lever lock things. Plugs sorted, exact start cables fitted and the 888 was running again. I just need to source some cloth electrical tape to finish off, before tackling the ECU repair.
That's nice job you're doing of rebuilding the loom connectors. I'll be interested to see how you get on with the ECU. The only time I tried to dismantle a 59M ECU it ended up destroying it. Fortunately was already knackered so didn't matter, I was just curious. The only place I've seen fabric insulating tape used in years is on Ducatis. I have no idea why they use it, there is probably a good reason but I overwound it on the ST4s that I had with self-amalgamating tape which I reckon is better at keeping the water out.

I'm working on an '06 Multistrada harness. I can't tell from your photo with the safety pin how you managed to release the wire/terminal to pull it from the connector. Could you elaborate?
You need a rod to push into the connector. Once the yellow slider is pulled out the connectors are held in by friction. By carefully pushing with the rod the connector will be released. There are extraction tools for doing this like this set https://www.ebay.co.uk/itm/222605086782 This guy pulls the pin out, you run the risk of damaging the wire. A better video
Ermm, a bit late with my reply, I've been distracted by my TDR of doom project... On either side of the hole where the male part of the terminal enters the female part of the plug, there are two other small holes, diagonally apart. I inserted the safety pin in one or the other, to push back the locating tang, allowing the individual connector to be withdrawn without too much force.
There are no locating tangs on the ECU female pins. They have a cut out over which a slot in the yellow retaining slide passes thus locking the pin in position. They are just held in place through friction.
Yes, well. After some time of carefully cutting along the joint and gentle prising, I managed to get the "lid" off, but even though I was being very, very careful, I managed to disturb and disrupt the thin wires connecting the electronics to the terminal (lower right most in the picture). So terminal pin 10 on the upper socket is no longer connected. I'm hoping this is surplus to requirements, because it is clear that most of the connectors are not actually in use, even though there are wires from the electronics to most of the pins. Hopefully someone will confirm this, it's too small to solder back on. Feeling with the safety pin, it seems that pin 10 female on the plug has no connector inside, but now it's back together, I can't look inside.
From your picture which pin 10 are you talking about? Each side of the ECU has a pin 10. Use this picture to identify If it is Pin 10 Engine you have a problem. If it is Pin 10 Body then you have been lucky as it is not connected.
Phew, it's pin 10 body. 888 will run again this weekend. I was born lucky, sometimes I need reminding. Thanks for the diagram! Best material for sealing joint? I was wondering about ducati gasket grey goo.
There were tangs on the female pins I removed, I found the safety pin, once inserted, moved the tang and made removal easier. Maybe this was because the plugs were from a Fiat Punto ECU/plug set I bought from ebay? I just pulled on the wire to remove, it was fiddly enough without trying to get pliers on the end of the pin. The yellow retaining strip definitely has to be slid out to one side though.
