You need 4 harnesses:
Driver door w/ power options. (2000 or 2001)
Pass door w/ options. (99 works and so does 00)
Dash harness (must get a 2000) and must have 2wd. 4wd or 4wabs has a different speed signal wiring). Engine won't matter but if you have a manual transmission you should get one with a clutch pedal position switch plug. Some automatics have this plug and just have a blank/jumper connector.
Engine bay harness (bay not engine get a 2000), has main fuse box connected and wraps around front of vehicle (headlights, etc). Get same options as dash (must get 2wd).
