i have an 09 SS/TC and i know its an easy process to install this guage. But when i hook everything up, this is what im getting.





i have reason to believe that my OBDII wiring is wrong. As you see here my green wire is on top of my black wire





And if u scroll down to the 14th pic in this thread, https://www.cobaltss.net/forums/how-...eptors-156222/ you will see that the red wire is on top of the black. So i believe that my wiring is wrong.




On a side note had unplugged the lil red thing on the interceptor n it took a couple of tries to start the car. now i have a CEL and my alarm system symbol is on while the car is running. I jsut plan to disco the battery n clear it out. But thanks for helpin and ur input is appreciated

 

Hmm... Mine did that red light thing first time. I unplugged the obd2 and plugged it back in to fix it. As for the wiring on the back, I have no clue what mine looked like but the plug only fit into it one way on mine. Is this an older gauge, it looks different then what I have? Are you starting the car up completely to test it? Did you plug or unplug the unit with the car on?

I would pull the battery fuse and let the car reset and try again.

I'm pretty sure ours uses the jumper on the Aeroforce so you want to put that back on there.

 

i did turn the car on the see if it would adjust but i got nothing. i did not unplug it while the car was running. do u suggest i plug n unplug from the OBD2 while the car is running? its not an older guage its a cn series w/version 3.7

i put the red jumper back on the guage.

 

I would try and reset your battery also. I had this troulbethe first time I hooked minee up. I wouldnt think it wouldnt be the wiring if you havent messed with it at all. That wouldn't make sense that its messed up but I guess a possibility. Once you reset it unplug plugs from the back of the gauges and make sure they are all the way in. Btw they don't lock in place. Also I would turn your car on before placeing it up to the obd2. Just in case its because its running only off the battery. Good luck. Let us know what happens!

 

im going to go out side n try thins right now. if im not back in 10 or 15 min, call the cops lol

 

I unhook mine while the car is running sometimes when one of the gauges goes off. I've never had a problem with it or heard of anyone else either? Mine are in my garage if you want to look at them.

 

while i reset the battery, turned on the car, and then plugged in my gauge. the same **** happened. The red led's lit up and w/in seconds of it being plugged in, i got a CEL and my alarm system light came on while car was running. i unplugged it from the ODB2 and it changed nothing

 

Hmmm... I'm going to look it up. I'm interested now. I don't have an alarm and idk if that has anything to do with it or not. Check if oreillys is open and see if you can't get it up there. They'll scan it for free and tell you the code for the cel and what's making it kick.

 

What are the numbers on the back501&502 or they both the same?

 

i tried look it up in Aeroforce Forum but found nothing. unfortunately i live in england n its 2:15 am n the is no o'reillys here lol. I do believe my OBD2 cable wires might be switched like i pointed out earlier. i even managed to find other pics of the where the red wire is on top of the black wire n located on the side of the jumper. unlike mine which is over the white wire n opposite of the jumper.

I also tried lookin for a wiring diagram to find out which one was power n ground on the connector n the gauge, but had no luck as well



the number on the back of my guage is CN401v3.7. could it be its the wrong gauge being that u mentioned 501?

 

Well incase its still underwarraty you can shoot an email to aerforce themselves. I know I would before messing with it. His name is Todd. A lot of guys had to get there's reprogrammed I know which I think is all free. But anyways here's the email for him admin@aeroforcetech.com

 

Maybe idk ill have to look at mine again. I might be able to get time tomarrow to check mine. Possibly tonight.

 

well just found this out.If you look at the application guide, it explains the part numbers. The "x" in CNx01 is just a variable where the color digit would go. If you ordered a red display, it would be a CN401. If you had ordered blue as an example, it would have been CN101. You ordered the correct gauge if you wanted red.

But i will email them and let them know what is going on. thanks for your help and Merry CHristmas

 

anybody have any other thoughts or inputs???

 

well an Aeroforce Tech contacted me and informed me that i was correct on the green and red wire being swapped. I gave them my address and should be sending me a new one. I also doubt this problem happens very often cause i could not find anything on this forum, Aeroforce Forum and Google searches.

I was wondering though if anybody had any thought that the gauge would be messed up cause the wires were swapped? let me know what ya think.

 

Damn that is weird, never heard of anything like that before.

 

Sweet man! Good luck

 

yeah it is weird, i could not find anything for the life of me. but i did see some pics of the ODB2 cable n compared it to mine and that led me to my assumption.


Thanks QCbalt09. When i get my cable in, imma post in here sayin if everything is working fine or not. Keep ya updated

 

So they wired it up wrong from the factory? You could probably just file down the tabs on the side of the plug?

 

yeah they did wire it wrong from the factory. yes i could have messed with the connector, but id rather have a new one then a hacked up one. plus its free so cant beat that

 

Glad you found the issue. The red jumper will have to be removed before install though

 

thanks Blazin07SS, but i do believe that the jumper needs to stay on being that i have an 09SS/TC. You have to remove the jumper for the SC if im not mistaken

 

This is correct.

 

Ah correct. Didn't notice the tc part lol

 

So AeroForce and i have been e-mailing one another and they came up w/a solution. Where the wires go into, there is a lil tab u can lift up with a needle or sumtin small and the wire will slide out. Like in this picture.



I swapped both the wires out and ended up getting the correct wiring. As you can see the red wire is above the black wire where it should be.




Then ended up being one happy customer when everything came on



P.S. how do you post a big pic to where it shows in the forum instead of it ending up like ^^^
