Here are some additional tips for replacing the 100 amp fuse in your MR2:

* Be careful when removing and inserting the fuse. The fuse box is live, so be sure to avoid touching any of the other fuses or terminals in the fuse box.
* If you have any questions about replacing the 100 amp fuse in your MR2, please consult your owner's manual or a qualified mechanic.
