I wa double checking all my fuses in the fuse box in the car and was watching everything line up until I hit one that the manual says should be a 15a and there's a 20a sitting in there? Will that hurt anything? Or should I take it out and put a 15a back in it? I didnt know if that would even affect function at all.

 

Put a 15a, 20amp will allow 5 more amps which could cause bad things.

 

done. Thank you!
