Just having a run at Taxi tonight. Looks like it's got a bunch of switches out. I need to test each of them, but I also found a homeless connector. I didn't trace it yet, but figured someone may know where it's supposed to go.
My taxi had cold solder joints on the pins that connector goes to. If your topper doesn't light or strobe, this would be a good reason why. Plus, yours looks a little burned so slide it on and off a few times.
