When I start the engin. all the gages don't move, it's like the engin is still off.

So the truck runs and everything but no instrument guages?

Customer: replied 7 years ago.
That is correct, I've already got the ignition switch, just need to know where it is located so that replace the old one.
Expert:  BigBob replied 7 years ago.
Remove the SIR fuse from the fuse block. IMPORTANT: With the SIR fuse removed and the ignition ON, the AIR BAG indicator illuminates. This is normal operation and does not indicate an SIR system malfunction.

I have uploaded the procedure here and here for you, let me know if I can help further.
