Not sure if this may help you but when I had all the gear for the ice install from @Absolut5 i was struggling to get all the wires pushed neatly behind as I had a mountain of wires / plug connectors / relays etc so I decided to cut off the big loom plug ,male/ female and soldered all the relevant wires then shrink tubed them , which was a massive help in getting them pushed back neatly !
