Thinking of replacing all the electrical wiring in my FJ40. There are way too many wires, most appear do not connect to anything. Under the dash there are several connectors, not connected and non-standard wires. Planning a big trip and dont want any electrical / earthing issues. Also need to add a few charging points.
I have studied the wiring diagram and seen a few diy youtube videos. Plan is to make a new electrical harness and then switch it with the cables in the vehicle.
Quick basic questions :
1- What is the recommended wiring gauge? Is it different for the alternator (its a thicker cable on my FJ40 - not sure if standard?)
2- There is a fusible link from the battery to the amp meter. What amp should that be?
3- Should i remove the original connectors? or would it be just better to connect to the old wire before the connector?
4- Need to add a few charging points, assuming 15 amp would be sufficient (same as a lighter).
Would appreciate any advice / guidance on this project.
