The shift lights would be just like in the above example. I haven't plugged into an SR3 XX yet, but it should configure just like the video above shows.
You can also put in a GS Dash. That is a small display that could show some alarms, lights, and a few measures on the screen. It can be mounted almost anywhere, so getting it in the line of sight shouldn't be a problem. I have a GS Dash and SLM along with the MXP.
@trailbrake, the GS dash sounds like a great option. Can it plug into the existing system and work as a slave , or secondary, screen? Is anything else needed to connect it?
The GS Dash is a slave to the PDM. Depending on the wiring in the car, it would need a data hub. The GS Dash is then just programmed as a CAN Expansion on the PDM. It's really slick and opens up some cool options for displaying extra measures, RPM lights, and additional alarms.
I'm looking at doing the same set up with the shift light module in my XXR. How did you go about adding the module into the AiM system? Does it plug directly into the AiM box?
