Yes it is a 20a fuse. I'd carry an assortment just in case. ---------- Post added at 09:07 PM ---------- Previous post was at 08:51 PM ---------- They covered the 02 sensor under warranty. That was cool cause they coulda just said no way since i had ltb. No they did not take harness apart at all. just tucked it back in and said its good to go. Well, that wasnt the case but I do thank them for at least covering the 02 sensor.
