EXT 3 fuse?

[pkp4life]

I have tried to search and came across several mentions, but nothing that was exactly answering my question - so please forgive me if my searching ability sucks, and its been answered. I was playing with some exterior lights and have them wired up to EXT 3, well something must have been wired wrong and Pop..... lights went out after about 2 seconds. So nautrally im assuming the fuse blew. I know the fuse is under the rear seat - but I have no idea which one! Is anyone able to tell me the location?

There are at least SIX different fuse types can be used in the INEOS Grenadier, being:

1. Mini blade fuse (not a low-profile Mini fuse or a Micro2 fuse);
2. JCase Low Profile fuse (895/PAL);

4. ZCASE® MEGA fuse (and MEGA SHUNTS);
5. Midi fuse;
6. MEGA Fuse (Midi style); and
7. some schematics here.

The precise specifications of each fuse type can be read here.
