Novice query about Manual Hubs and the flashing 4wd light

Hi all. Total novice to mechanics and Jimny's but after reading all the posts on here I managed to test If the 4wd was engaging on a 02 plate JLX with manual 4wd selector (Thanks for so much assistance! ). Found out that it is what seems to be the common problem of 4wd is working the dashboard light is not.  For sanity's (and at the moment speed) sake manual hubs purchased and being fitted this weekend (by a mechanic not me lol although he has agreed to teach me).
So the novice question.  All of the topics on here talk about 'fooling the system' by pluging the vacuum lines etc.  Why can I not just remove the fuse from the 4wd section of the fusebox ? I will know when I've put the hubs in, I'll know when I've selected 4wd.. all I will want is Not to have a flashing light but not one topic on here mentions the fuse. 
Thanks in advance

Hi,

The hubs locking is only part of the puzzle, after they lock the transfer box engages the front prop shaft so if you remove the fuse, your manual hubs might be locked but there will be no drive to the front prop shaft and differential.

The reason for plugging the vacuum, or linking out the pressure switch is it fools the system into thinking that the hubs are locked and then the 4wd controller can command the transfer box to engage drive to the front.

Hope that helps.

On a pre-2005 Jimny with the manual transfer case the easiest way to achieve what your looking for without upsetting anything else is to unplug the 4wd switch on the transfer case. It's the higher of the 2 connections, lower one is speedo.

Mine is flashing now for 8 years  ​​​​​​
When you're in any off road situation you no longer notice it. To busy avoiding the obstacles 
Just make sure you blank off the 2 stubs near brake calipers on each side. 
Imo axle looks nicer with all the rusty pipe work gone

Thanks. Vary clear to understand . There had to be a reason no-one had done it - I just couldn't find it
Good job i can leave it up to the mechanic really !

Jack, no rusty pipework on my axle and I have fully functioning, manually switched vacuum hubs

Busta I do like how you have routed yours it looks neat
