The 3rd generation Mitsubishi Pajero was produced in 1999, 2000, 2001, 2002, 2003, 2004, 2005 and 2006. During this time, the model has been restyled. In some countries it is known under the name Montero 3. In our material, we will show the general arrangement of electronic control units, describe in detail the fuses and relays of Pajero / Montero 3 with block diagrams and photo examples of execution. Let's highlight the fuse responsible for the cigarette lighter.
In the presented material and your Pajero (Montero) 3, a difference is possible, which depends on the region of delivery and the level of equipment. check the purpose with your diagrams on the back of the protective cover.
