Where's the fuel pump fuse?
 
My first thread :D
My LC arrives next week but I can't get the tracker/immobiliser required by my insurers fitted until two days after delivery... so... does anybody know where the fuel pump fuse is so I can rig up a temporary hidden switch?
I've googled and I'm guessing it'll be in the boot/trunk - am I correct? Anybody know what rating it is or which position it's in?
Huge thanks!

Your car has these features built in, no?

Hi, thanks for the reply. I’m in the UK - I don’t know what the US market gets but here the LC gets a basic alarm and immobiliser but also ‘keyless go’ which means without a faraday pouch/box to block the key signal from inside my house the car can be unlocked, started and stolen with a signal booster. The OBD diagnostic port is another route to theft if it can be accessed without alerting the owner. Or it can be stolen at knife point, or they can enter the house and ask politely for the keys. It’s very rare but it does happen.
Because of this the insurers of high value cars here sometimes need a tracker fitting - I’m doing this plus additional remote immobilisation but I can’t get it done quick enough.
My plan is to go ‘old school’ and fit a hidden switch - I’ve done it before but I can’t find online info about fuse layouts on the LC.

Can't answer the question re: fuel pump fuse BUT if you want to immobilise the keyless entry then it's a five-second task. To deactivate the key(s), simply hold down the lock button and then press the unlock button twice. Wait till you see 4 flashes from the led adjacent to the lock button and you'll find the key is now dead. Take it to the car to convince yourself but trust me the key is dead and therefore no relay theft can take place. For the manic amongst us, pop it into a faraday pouch/box and then hide that where burglar Bill will never find it. Also remember to keep the spare key deactivated and quite separate from the main key.
Hope that helps, and oh btw, I'm one of the aforementioned "manics" :-)

Thanks - I didn’t know deactivation was possible. I think I’ll probably be disconnecting the battery or something just as drastic but the key deactivation is a useful tip :)

I tried that but it doesn’t work on US key fobs.
Does anyone know how to do this on US fobs.
Thanks

Never mind.
It does work. Comes back when you press any button.
Thanks Brinylon.
