Recommendations
The sound/heat insulation of the bulkhead is the foam located in the engine compartment at the rear of the carburetor.
This insulation has the major disadvantage of retaining moisture and causing oxidation of the bulkhead. In addition, over the years, it has become seriously ugly and is starting to crumble. We have therefore decided to remove it permanently.
Removing the insulation also allows you to see much better and be much more comfortable to work on the wiring harness and heating hoses later.
Opinions are divided regarding the removal of the bulkhead insulation. Some Mini enthusiasts believe that the increase in noise in the passenger compartment is too great. To each their own priorities.

Secure the wiring harness

Slightly bend the 3 support tabs to hold the wiring harness in position. Bend the tabs by hand.
Check that the tabs are well protected by plastic sheathing. This will prevent damage to the electrical cables.
Do not compress the harness. It must be held but not blocked.

Let's take a short break to admire this magnificent bulkhead. We can see more clearly and it will be much more practical to access the wiring harness.
Op 09
Reinstall the air filter housing (➔ see the tutorial ''Replacing the HS4 air filter'' Steps 10 to 13).
