Once you have your wiring harness and your old wires removed, your first step is to install the fuse block. On many vehicles this is as simple as placing it in the factory position.

Once you have your wiring harness and your old wires removed, your first step is to install the fuse block. Many fuse blocks connect to the factory bulkhead connector with bolts, in other cases the fuse block may need to be screwed or bolted to the firewall or another secure location.
  
 
The next step is to begin routing your wires. While doing this keep in mind any sharp areas that may sever a wire and secure the wires as good as possible. This will prevent the wiring from deteriorating as quickly as they would if little care is given. Begin by routing your longest wires first, as, quite often they will get in your way while dealing with the shorter wires. Once these wires are routed and secured you can begin attaching them to their connections. The following order is reccomended tail lights/fuel gauge sender, headlight/horn, engine compartment, interior lights/speakers, power windows and locks, heater and stereo, dashboard. Keep in mind that certain connectors are not easy to find new, therefore in some cases you must solder or crimp an old pigtail onto the new wire. Furthermore it is suggested that a maxi fuse is installed rather than a fuseable link and while some wiring harness's reccomend the main power come off the starter live connection, running the wire straight to the battery can be a better way to go. Such a case would be an offroad vehicle where water or mud could cause problems if the main power wire is connected to the starter.
