swapping erlina wiring into executive (VS Commodore)

[Tommodore]

so i want to swap the wiring from my berlina into my executive so can upgrade a few bits and peices.... mainly what i want to know is how hard is it ? And how long will it take ? is it really that big of a job ?
Before you ask im swapping it into an executive because im wrecking my berlina

What bits and pieces do you want to upgrade? Before you start have a look to see if the extra wiring is already there. Sometimes they use standard wiring and just leave the unused wires loose behind the dash or wherever they finish.

i have checked most of it isnt there i wanna add the cruise control, digital dash cluster and im thinking about doing the climate control aswell but idk about that part

Climate control means swappi g out the complete heater box

is it possible to swap out the harness without changing the climate system cause they are different plugs

 

[LordMayhem]

Use the plugs from original harness is what i would do in that case

so basically use the the berlina loom and just solder and heat shrink the plugs from the old one ?

Ive done what your about to do. It is abit of a big job if you don't know what your doing. I swapped out everything mate, the most time consuming is the heater box ( whole dash has to come out, which you have to do anyway), and putting the drivers side wiring loom through the fire wall and yes it has to be done because of a c/c sensor at the front on the aircon condenser. Can be done on a weekend easy.
