Sensors mystery - HELP

fwiw and while im sure you know, just in case... marine heatshrink is a thing and contains 'glue in the sleeve to provide an extra seal against moisture ingress.
you may want to ebay some for the final fit..

I have a lot of normall heatshrinks. But never heard that exist glued version. Good to know for buying next time. Thanks.

EDIT:
Alternative to that will be buy a new 1T5 cable where will +5v pins work?

But whatever, it comes back to the same thing, because I have to shorten harness, anyway.

Ok. I am finished. Want to know your thoughts abut this, but be gentle please

I took a time. I thought a lot about how I would combined wires in which direction and how far will be. But this can be fine. I used only heat shrinks (not electric tape), sometimes from both sides, and all cross point wires turned to down, that water harder to coming in.

I think that water must not enter, at least light rain, in which I sometimes drive.

The green heat shrink is wire which blocked and not going anywhere.

Also, I could have finished sooner and had less struggle if I had bought a new harness 1t5 and cut & connected 9 wires, but that always can do anyway

This Stuff is pretty good for finishing off the cable job

it just takes patience winding it neatly around the cables..

looks like you have all the extra wires feeding into the bottom of any splices to avoid water capture..

Enjoy the e-bike..
