What are you trying to convert to LEDs? If you're not getting into the dash and controls, it should be pretty much plug-n-play. I have done this with my 90. Most everything is either 32mm festoon bulbs, or mini wedge of some sort. The lighting guide at
http://www.sylvania.com is pretty accurate. Pictures of the lights you're talking about in the consoles and near the door handles would be helpful. They may not be listed if they're sold as part of an assembly from Nissan.
