'96 Lumina APV,3.4 engine wire routing HELP!!

[edm guy]

Hello,
The above mentioned vehicle overheated and blew the head gaskets,warped heads, and other terrible things.Service engine light came on ,but the driver (wife) did not think that stopping immediately was neccesary. Quit, 2 miles from home. Wife and small child in vehicle on four lane road in the country @ night with $ 150.00 dollars of groceries. Call local tow guy, he says he can fix it. 5 weeks later, job half done, wife gets peed off, pays the guy what we owe him,bring van back home. All engine wires CUT.Another week goes by, friend says he will fix it, takes it to his house, this was memorial day week end 2003. I have meanwile bought two new cars on the same day, almost walking !
Friend has yet to complete job, can he yes most likely. Am i somewhat upset yes. 10 hr. job @ dealership, I checked. Meanwhile, Does anyone have a wire routing guide for a 96 Lumina APV,3.4 . Any help will be appreciated greatly, we have a schematic, Thank you and God bless you
