What is the best way to unclip the injectors wiring
that runs under the V6 inlet manifold

dont really want to take the manifold off
but cant get hand in to unplug the injectors

lol I think you've answered your own question! Its a 15min job to unbolt the manifold enuf to access the rear injectors. 12mm socket, 10mm ringy, bladed screw driver.

I didnt have to undo the manifold

long handled thin flat bladed screwdriver

update
to connect up the injectors I
had to remove the inlet manifold but

left the wire clips off the injector plugs for now
