Evening Gents, So I've already swapped in a 6 gauge cluster from a 2004 monte carlo. Even added leds.All the other gauges work in my 2003 impala. Just curious does anyone have a clear answer on how to get the oil pressure gauge to work on a 3.4L? I've searched but I keep finding the same threads. I've seen a few saying to just swap the oil pressure sensor to that of a 3.8L and I've seen a rabbit hole of a thread where the guy was saying you'd have to swap bin files in the pcm. I don't see the point in doing work on the pcm for that but I'd swap a sensor or whatever. I've seen the oil pressure sensors of both and from what I can see the sensor for a 3.4L only has one contact inside vs the 3.8L which has 3 contacts. So if anyone is out there could you throw me a lil knowledge?
