I'll try it again. I know the anti-theft modes work fine, but maybe while the car is running/moving it isn't as secure

So, an update: I picked up a "new" OSS sensor and a "new" gauge cluster (off a wrecked mustang). I didn't have time to put the cluster in, but I did swap out the sensors.

The speedometer is still off and still twitching and jumping all around, when data logging, the logger reads almost the same as the speedometer (including when it jumps and the car is standing still), it also reads that I still have the P0721 code. BUT, when using the gauge DTC thing, it no longer has the DTC about the cluster being damaged (says dtcNONE).

Maybe I'm wrong, but shouldn't the OSS have fixed the twitch and speed problem and the cluster have fixed the cluster problem, not the other way around (well I havent put the cluster in yet)!?

I did notice that P0721 says something about "interference" (different from the P0720 code), and when installing the "new" OSS sensor, I noticed that the wires that connect it to the vehicle hang low near the O/R midpipe and MIL eliminators, or get magnetized (stuck) to the transmission, should they be separated? And I noticed some weird wiring in it (may be stock, I've just never seen it)

Ahhhhhhh
