These pictures are from Tom Marrion of his smart looking Jimny.
The Jimny is fitted with an ARB difflocker in the rear axle. These difflocks are operated by compressed air, therefore an air source is required. If you purchase an ARB brand compressor these have a small air tank built in that permits operation of the locker but if you want to have more air, suitable for other accessories or for inflating tyres then a large air system is required.
The previous owner installed a VIAIR air tank system combined with a T-Max compressor but only carried out a quick minimum installation.......
As can be seen in the problems section, the Jimny wiring needs some serious attention - see Wiring!
A whole series of accessories have been fitted and the wiring for these needs to be rationalised and tidied up. In many places domestic mains cable has been used and lies loose on the floor.
