I bought a wiring harness for my P5 so i could put in a radio, but it didnt fit. The package said for "Mazda 90-up" but doesnt fit mine. So im guessing its for '90-'99. I paid $18 for it, and selling it for $11 total by envelope. If your thinking why dont I just take it back, its because I lost the little plastic package it came with. Let me know, and remember its brand new.
