My question is. What wires do the resistors go on?
Thanks, Matt ...

 

OZZYRULESME...Here are the two threads I found on the matter. I labeled them one and two and put lines between the postings to make it a little easier to read. I hope it helps.

#1-For the DVD bypass I used a Momentary Pushbutton Switch, Normally Closed, rated 0.5A at 125VAC, 0.3A at 50VDC. The part number is 275-1548 at Radio Shack. That was for a pack of four.

Run that green wire(thats supposed to go to the e-brake) to one side, and then run a wire from the other side to a grounded connection... I actually ran this wire to a bolt on the e-brake! Turn it on, push the button, and it should work. Let me know if you have problems.
----------------------------------------------------------------------------
so its the green wire or the orange wire..cause i was told the orange wire..for the avh-p4000dvd
----------------------------------------------------------------------------

Exactly. Try grounding the green wire first - I tried it, and it didnt work, because like I said, the push button switch helps to replicate the pushing on and off of the e-brake - but on an old JVC in dash DVD unit I used to have, I just grounded it and it worked perfectly.

If that doesnt work, try getting that momentary push button switch, run that green wire to one of the posts on the switch, run a wire from the other post to the vehicle ground. That should make it work.



#2- Re: "SYS" warning light after aftermarket HU install (kmath)

This is a copy of Marco Polo's previous post:

1. Buy (2) 1 kilo-ohm 1/2 Watt resistors.
2. Disconnect the negative battery cable.
3. Remove the receiver.
4. Connect one end of both resistors to ignition power. (Yellow wire in the car.)
5. Connect the other end of one resistor to the purple/white wire in the car.
6. Connect the other end of the second resistor to the grey/black wire in the car.
7. Cover all connections and completely cover the resistors.
8. Reconnect the negative battery cable.

No more SYS error!

 

Battery is low! My 90 did the same thing before I got a battery tender when it sat for a few weeks!

 

The sys error had been on since I bought the car(1 1/2 yr). Last week the lights on dash board of the trip monitor were going on and off. Mostly off. What i found was a loose plug behind the trip monitor on the right side off the dash. Just remove the four screws from the bezel that's around the main instrument panel. Remove it or leave it loose. Reach up behind the trip monitor and push in the plug to re-seat it. You can not push in the plug any other way because the wire is to short. Possibly see it with a mirror. I found that out buy removing it which was difficult and unesassary. So closed up the dash. The next day I drove the car and realized that my sys error had gone away. I did not disconnect the battery or touch anything else. It makes sense cause all those buttons work all the dash displays.
Good Luck

I've tried getting to http://www.corvetteforum.net/c4/dave8476/index4.shtml from within this thread, and from the audio faq section. I've used different browsers, and three different system. In all cases it comes back as not found or timeout. Is that still a valid URL? If not, is the information available elsewhere?

Thanks,

ChooChoo75 what are you trying to find out?

 

It seems the link to the service bulletin in this thread above no longer work.
I have no idea what happened to them.


At one time the link above pointed to a GM service bulletin explaining an issue with a flashing SYS after installing an aftermarket stereo on some cars.
That link no longer works.

 

You are correct about the link to the TSB. I've tried accessing it from multiple threads, always with the same result. I'm off to my local mechanic to see if he can print it out for me.

Thanks for the quick responses. I'm tired of the SYS issue, and will start with the resistor fix, I'm just looking for as much detail and explanation as I can get before I start the surgery (and avoiding as much upside down over the door hump time as possible - quick in and out).

Thanks,

Clay

 

Found it!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!
