My only suggestions would be...
1st) press capslock... I am hoping you just missed the fact that ITS ON
2nd) Its a crappy situation, such is cars, hopefully (for you) you lack the moral and ethical character to be able to sleep at night dumping off expensive problems on other people KNOWING they are there. Think of the excited family, happy to finally have a car they fit into, its spreading their finances thin but its been a long time coming and they need it... only for a problem that has been there to pop up a week later.
If 2 grand doesnt work for you, get on car-parts. com and find a new harness... or at least locate local yards that have the same rig as you, I am sure it would be MUCH cheaper.
