Can you tell from these two diagrams from the Nissan parts system which harness you need? The numbers are just locator codes. Once you have the correct harness located, the locator code will direct you to the right PN.
Go to Nissan eStore, Parts, and enter your VIN to get the right vehicle attributes set (KC or CC, 4WD and build date, which is important since there is a change in harness PNs that occurred in 08/2006). Then search for "harness," which should bring you to these section 240 diagrams. There will be a table on the left. Find the right locator code, click that, and it will bring up a page with PNs you can use to source the part online or at your dealer parts department.
Looks like the part lists for around $300, depending on model specifics.
