Discovery 1 shell swap need help

Good afternoon guys

Basicly ill cut a long story short lol
I had a 300 tdi manual and i managed to roll it at a play day

So i bought a 300tdi auto because the shell was very good i have swapped the shells over so the auto shell is now on the manual chassis and i have come across a engine loom issue

The plugs that come in to the shell
Brown (fits fine )

I have removed the auto ecu and put the egr controll box in out the manual shell so thats fine

But the other white plug is shorter on my manual engine loom so were it joins to the loom inside the shell it carnt because its too small

So basicy i am at a loss to what i should do now

If you have the loom from the auto then you will have plenty of spare wire, so cut and splice using quality butt connectors, the one’s that have heat shrink on the ends, try and match the colour codes to make it easy on your self,
Having a spare loom will make it a doodle
