This is a set of two. Please comment if you need more. Isuzu Elf 1DIN genuine audio (model: TN0041A) part number: 897874-8071 can be used in another car. The basic wiring is connected according to the colors, but the brown and blue wires are questionable (I haven't used them). I apologize, but please use at your own risk. The connector was difficult to remove, perhaps because the material is slightly soft. For now, I cut the fixing barb in half, and it got better. Also, it seems that the insertion may be tight depending on the audio. Because the illumination is amber, it may also suit old cars like neo-classic cars. It will be shipped via Nekopos from Seven-Eleven.
