Another take on fixing the flashing SYS?
I'm about to begin taking the Vette apart for the full system installation.
While I'm doing the work, I plan on fixing a lazy antenna, and the flashing SYS that's a result of the aftermarket Kenwood that's already in there.
I'm going to use an Alpine CDA-9856 in place of the Kenwood unit. The Alpine has an "illumination" circuit specifically described as "This lead may be connected to the vehicle's instrument cluster illumination lead. This will allow the backlighting of the CDA-9856 to dim whenever the vehicle's lights are turned on."
Now, suppose I were to connect this lead to the LED and LCD circuits as opposed to installing the 1k ohm, 1/2 watt resistors, would this do the trick? I've read through the forum, the faq, and the FSM, and I haven't been able to answer this question yet. Anybody know? Is the circuit looking for just voltage or data bits?
Thanks!

That is covered in the faq. I don't have a problem with that. What I'm asking is if I could connect the illumination circuit of my Alpine to the LED and LCD circuit in the car to avoid needing the resistors?

gixster - sorry for posting a generic answer I guess I should have read your thread a little more thoroughly. Personally I dont think it will work but its worth a shot... id be more concerend with frying something

So, having said that, when I put in the resistors, what's the step by step? What are you guys doing, just inserting one end of the resistor into the LCD / LED plugs, and then soldering that to one of the switched hot wires? Is there a more secure or better way to do it at the plug end?
There's an ignition circuit out on the Alpine, and I have to take that wire back to the plug in the storage bin, so I was thinking maybe I could splice into that wire.

I am with pentavolvo on this one.
My concern would be that the line in question isn't the illumination, but a data line used to feed the SVC feature, and confirm the presense of the stereo to keep the CCM happy.

How are you guys tying in the resistors to the wiring harness? Just shoving them in there? Soldering them to the pins on the connector?
