So your comment got me digging deeper. It seems like you are right, that the part is actually the same for GT350 and all other Mustangs. Nevertheless I do not agree with your logic of just making one part instead of two with different functionality. This really depends on the costs in the end. If they can save some money, the will do that. Bi-colored LEDs and the circuitry to support this is quite an effort and this is not used on a regular Mustang.Just because that's how it's used in the GT350, doesn't mean it's not the same part #. That part is just a LED array. It'll light up whenever it gets a signal, whether that's from the IPC or the ACC module. And since I don't think there's a lot of cars with ACC, and there's not a lot of GT350s, it's probably more cost effective for Ford to use the same part for both, than maintain of inventory of nearly identical parts. Just add some bi-colored LEDs, change the circuitry inside, and calll it a day, charging the whole thing to Ford Performance. That's even more likely if the Road & Track story about itis true: "the story goes that a Ford Performance employee thought about other uses for the collision warning system in his late-model Taurus SHO, which flashes some LEDs against the windshield. He realized that the existing tech could be reprogrammed to function as a shift indicator without a whole lot of effort. He modified the unit on his SHO, then showed it to the brass. They fast-tracked it for the GT350, and here we are." And then there's all the Ford compatibility lists for the part which shows it working for both.
So I'm just asking if my part is before the GT350 revision, or if there's something else that's different between them.
Nevertheless the IPC controls the HUD function. I was not able to identify any configuration changes in the IPC, which would enable the shift lights in a non-GT350 IPC. So it seems like this is really related to the programming/calibration of the IPC.
What would be possible, built a little Arduino or something, which sniffs on the CAN bus for the RPM and the HUD warning light and controls the HUD accordingly. What is tricky to identify the messages you need to send to the HUD for the shift indicator lights to show. Someone with a GT350 would have to sniff these with an appropriate tool
Or you switch to a GT350 IPC, which some guys have done before.
