I donno jack about wiring cars.. HELP.....

[Kienai]

A Nissan mechanic told me that I need to replace all the wire harnesses that's in my car, the engine bay, the interior.. All of it... I don't even know where to even find one for the interior.. Or how I am going to install it.. I know its not going to be cheap.. So if I am going to do it, I have to do it right... Otherwise its going to be a ***** trying to figure out what I did wrong.. So can anyone help me with this.. Provide me with some info as to what I should do or where to even find the harneses or picture instructions? Anything... Right now, my car doesn't have interior headlights or brake lights.. Sometimes it doesn't want to start.. Its bad... Someone help...

what happened to the old harness? Did something happen to it? like catching on fire, or melting due to an electrical spike?

It's rare that i hear "all wiring harnesses need to be replaced". It could be a faulty connection somewhere, bad ground, etc. The wiring harnesses on or cars were not mad cheaply, so I can't fathom a total replacement of the harness

That's what the mechanic told me.. I guess I have a really bad short.... I guess its pretty much through the whole harness.. That REALLY sucks.. I've owned my car for only about 8 months..
