I have no gauges warning lights or havoc controls. Truck also went into limp mode! Scan tool said it's the Master control relay but I don't know the location on that relay! Do you think it's something else!?
Thanks for any and all help!

What was the trouble code retrieved?
Do you mean the Body Control Module?

It was code 30 on a Genius scan tool! Said master control relay!
Do you think the body control module would make these symptoms occur??

I need the OBD II codes to understand the problem better.

Yes, the BCM can cause such problems.
