The op stated he used 22 ga wire. Note that SAE 22 ga wire is rated at 0.92 amps. (Can go higher, 1.5 a depending on temperature rating. If not marked on wire, assume lowest rating). Nonetheless its dangerous.

 

The wire used must be rated at whatever the branch circuitry is rated. IE if the fuse is rated at 7 amps, all wire in the circuit must be rated to carry 7 amps. (If a short occurs, the wire will be exposed to the full rating of the branch circuit, {which is the rating of the overcurrent device}, before the fuse blows). 

 

The problem isn't if the fuse blows, but if it doesn't, as in a partial short fault and only draws 6 a. The fuse doesn't blow, but the insulation melts causing sparking and/or fire.
