Need a hand with vy adventura seat transfer into vt wagon

[Vt ss 5.0l 5sp wagon]

I've recently swapped out my vt wagons cotton seats for vy adventura leather and heated seats... But have been told by six different electricians that they can't rewire it without the wiring diagrams, ( which they can't get supposedly) just wondering if anyone knows the wiring diagrams needed
( vt 5.0l wagon and vy adventura sx6, 4way to 8way)....
Found a thread on here stating the just of the job, which seems fairly simple though I ain't confident
