If I only had a single wrench, I hope it's 13mm. 10mm for thermostat bracket bolts.
Does not engage A/C, rear defroster. Horn is not connected either (for programming).

The horn relay location is not in the fuse box under the hood, it is located in an unmarked and unlabeled box to the right of the battery. This is not noted in the owner's manual, or the repair manual.
The horn fuse is labeled “horn & PCM”. From what I can tell, it is simply as a failsafe of sorts to disable cruise control if the horn fuse is blown. Simply pressing the horn button does not appear to disengage cruise control.
