Problems w/ remote start! 04 Kia Sorrento

I had a customer stop in our shop today looking for a remote start for a 2004 Kia Sorrento.  He had Circuit City install one about a month ago and had all kinds of problems.  They blew some door lock module which cost $575 to fix.  He came to me looking for us to install one and with Circuit having those problems I'm a little uneasy about jumping into it.  I checked the wiring diagram on Installz.com and it looks pretty clear cut, no special instructions.  The customer also is just looking for the remote start, he doesn't want keyless or any extra features.  Can a DEI system be hooked up like that and just not connect the keyless wires?  He has the key pad where you have to swipe it to start the car, but it's been disconnected so that shouldn't be an issue.  If anyone has done one of these or a similar Kia please write back and let me know.  I don't want to get into this if it's gonna end up being a $575 repair again.  I'm sort of new to this stuff, less than 10 installs, so I'm looking for some more experienced advice here.  Thanks,

Jason

looks pretty clear to me

blue = lock                   In harness above fusebox in DKP

white = unlock             In harness above fusebox in DKP

factory arm  =  Dk green       in harness above fusebox DKP

factory disarm =  orange         in harness above fusebox DKP

if it is the base model.....use the lock wires ....there are negative triggers

I think the guy tapped the wrong wire.........well he learns the hard way...575 dollars hard way

enjoy

No surprize there...ciruit city can always find ways to screw up an install.

Sounds, like you like to think before you act, which is good. I'll admit, I'm no speedy installer, but everything I do is done right the first time. I could never make it in a shop, but people love my driveway work!

He definitly tapped into the wrong wire! He should've used a multimeter.

Installers: look up the laws in your state, chances are you are not liable for any damages done while you're at work. They should have insurance and they should not be taking this from your check.  I know a few installers who got screwed like this and it's not right. These guys were good installers too, but sometimes sh*t happens.

My boss tried to scam $300 from me to fix a broken window in his delivery truck, I caught it while I was doing my taxes and filed a 'non-payment of wages' complaint form. I was refunded the money withing two weeks. Sure, I let a V6 motor on a pallet slide into the rear window.....but it wasn't my truck, certainly wasn't my problem and for $7 an hour...I could care less.  

I also worked at a stereo shop where they did this, but none of my cars ever came back. When I quit, they tried to hold my pay incase they 'found a problem with a customer's car' ....they soon learned the law too. For $7.5/hour I suppose I should have sent out a few hack jobs....but that's just not my style, the customers come first. 

Just have pride in your work and you will realize that fixing bad installs is a great way to win new customers. good luck!
