While I agree that power windows / locks are going to be an involved wiring, relay and motor transfer ordeal...

I am going to recommend that you further investigate the trunk of the donor 240 and locate the source plug for the trunk lock.

I believe that it originates somewhere near the hinge on the driver's side. IIRC, I did NOT have to pull wire to add a power trunk release to the 84 244 DL (which was my first Volvo - in 1991???). I believe that I was able to find the plug in the trunk of the donor car, identify an identical plug in my car and then pulled the glovebox / center support surround and found the button end in the interior.

Never hurts to check. I could be wrong... It's only been 27 years, LOL.
