Old stereo equipment used this type of bulb. I found them on stereo web site. I hooked the Kaptin up with them, so he should have some in stock. I have a few, because I still have a few 03's come through my shop.
I`ve torn the whole oem harness out. Some mexican had f...cked it all up. You almost couldnt see the battery from all the wires when pulling the seat off. Tons of split onto splits onto splits with no soldering etc. And alot of shit not working.
Installing an Ultima + as we speak.
