okay so i hooked up my Pioneer p4000 and for some reason now my guages don't work, like nothing works.. and where it says my mileage and stuff it's just a flat line, so when i'm driving my blinkers don't show up it says my e-brake is on, and the whole cluster is just at the red line on everything like the car isn't even on.. has anyone had this problem or know what could be wrong? it's not a fuse because we checked them all.. if anyone could help that would be magnificant because i really don't need a ticket because idk how fast i'm going lol thanks!

car is for an 2006

thanks a lot! ill check that out. couldnt find a thing like that when i searched..

 

no problem, that should help you out

 

same thing but your harness is diffrent he has an 07. you should have a light blue colored harness not a grey one

 

okay so we have tried just about everything and it's still flat lining but now the car won't start or try to turn over or anything it's just silence.. but when we unplug the harness that we bought the guages work fine and theres no flat line... any advice? i honestly don't know what to do here and it's really worrying me that i did something to my car... :/

 

What harness are you using, and if its for an 06 (your sig says 07) than what model cobalt is it

 

2103 i believe. and its for an 06 chevy cobalt ls. the 07 is my old car.. thanks for helping!

 

Ok
The 2103 is the right harness but it sounds like you have the LAN wire in the wrong place.
What fuse did you tap for the ACC wire?

IDK, you got me scratchin' my head.
If everything goes back to normal when you un-hook the harness then nothing in the car is blown or wrong at all the problem lies in the Harness or the new head unit.

I know this sounds like a pain but pull the harness apart go back and re-trace your steps it could be the wires are mis-matched somewhere but I'm sure you have been over it all already.

Emp would know better, he installs for a living I'm just a weekend warrior.
I know I've herd him say something about having to re pin a harness but I'm not sure which one, and I think it was for the Pioneer systems

On the harness that comes out off the car there is a dark green wire, thats the Lan Data wire, I'm sure your problem revolves around it somehow, but I'm not sure how (I know not much help huh) focus your efforts on that area and hope Emp comes around soon.
Sorry I couldn't be of any more help

 

well we took it all apart and now were having the security light come on in the instument panel and the car won't start now even tried jumping it, we've gotten the light to come off by keeping the key in the ignition on ACC but when we try to start it, it still won't do anything, i honestly have no idea what else to do i'm very worried i did something bad and now i'm gonna have to pay big money for it...

okay so i got it to start!!!!!!!!!! so now were gonna have to see if it's the harness that we bought is bad...

 

and the harness color is.... i cant help you unless i know

 

gray i think...

 

ok man u got an IM i can get ahold of u on?

 

thats the problem its the wrong harness... you need the blue one or need to re pin it let me know if you want the pin outs

 

yeah i have an IM.. yahoo or aim? could you give me the part number for the harness? and naw pinning it out or whatever would take too long..

 

the metra 70-2103



it has to be blue... all the speaker wires are on one side as well

 

well ****.. they sold me the wrong one so i pertty much just threw away 50 bucks because i went to a shop that doesn't have exchanges or returns no exceptions!! dangit!! and i also paid someone to finish the job who ended up ruining it more, which was another 50 so i pretty much wasted 100 bucks!!

 

that happened to my LT and we just used the same harness jsut rewired it. pull the pins out and put them in the right holes

 

isn't that like a pain in the butt to do though??

 

HOPE THIS HELPS ,

ITS REALLY NOT THAT HARD TO DO, YOU JUST HAVE TO RELEASE THE LITTLE FINGERS THAT HOLD THE PINS IN AND THEY WILL POP RIGHT OUT OF THE HARNESS.SWITCH THEM AROUND TO WHAT YOU NEED. GOOD LUCK THOUGH

 

my boyfriend still thinks it's a pain in the ass and thinks it would be easier to just buy a new one, the cheap kind though

 

New Boyfriend Then Lol

 

naw its easy, just get a needle and their will be little holes on the inside of harness and just stick ur needle in them and the pin fall out

add me on yahoo
