Sorry if I don't know the correct place to find these,

I diagnosed my car having an alarm issue when it was suddenly not turning over to start after getting gas.

I measured the resistance in the ignition key and bought the same value resistor at an electronics store and put it inline in the wiring harness so it sent the same signal of the key.
Sometimes after a lot of use the contacts or wires can come apart in the ignition cylinder and then no longer read the resistor in the key.

It worked perfectly until very recently and after a new transmission was put in but it intermittent.

Some of the covers are missing from the fuse boxes and part of my diagnosis and attempt to reset the alarm involves the alarm fuse.

Can someone please let me know the location of which fuse box and which fuse? My GM shop manuals are in storage not close.

Thanks In Advance!
