So I just finished a full flash of the dsp2 tune I have and installed the switch. The truck starts and runs but haven't tried to move it yet. But the radio, fuel, voltage, ect, and oil pressure gauges do not work and the abs MIL is on. Also, the dome light and the keyless entry is not working either. What did I do wrong and how do I fix this problem?

Thanks in advance

I would unplug the switch wires from the ECM and load the stock tune in it again to see if the switch is the problem or maybe something got unplugged durring install.

OK, I'll give that a try in a bit. After looking at both the stock and modified tune I've noticed that both tunes are not the same OS, how can I make them the same OS?
