Default WRX sedan to 2.5TS wagon wiring harness swap

I couldnt find much while searching.

I am swapping a 2002 WRX sedan harness into a 2002 2.5TS wagon shell

the front dash and engine harness is fine, however the back half is the problem.

the sedan and wagon have much different tail light wiring etc for the rear, as well as fuel pump controller wiring.

Can I easily merge the existing wagon rear harness to the WRX sedan front harness? The 3 plugs are identical on the passenger side lower B pillar with the exeption of the largest plug having the different wiring.

thanks!

We did a 06' WRX sedan swap into a 2002 TS wagon. You have to use the fuel pump controller from the wrx and splice in additional wiring for the difference in the accessories of the rear of the vehicle (rear hatch door lock actuator, rear wiper, etc etc).

Ok thanks. Do you know off hand what each of the 3 large plugs that separate the front and rear harness are specifically? They are located at the bottom of the passenger side B pillar
