I've installed a JVC KDSH-99 Head Unit in my 94 TT, and everything is working great except for the power antenna. It ceases to move up at all when the unit is on, or put into Tuner mode. I've checked and double checked the wiring from other posts on this forum. From what I can tell, the Blue/White wire from the JVC unit should connect to both the Black/Red and Pink/Blue wires on the Toyota harness.
The JVC to Universal and Universal to Toyota wiring harnesses I am using are connecting all the appropriate wires to make the antenna function, still no go.
Last night, out of curiosity, I reconnected the factory Head Unit to verify that the antenna was still working. I connected the harness, the black antenna lead, and a smaller gray wire to the headunit and everything works.
Out of curiosity, does anyone know what that gray wire is? Its a gray wire that looks like the black antenna lead, but a tad smaller. It plugs into the factory head unit right next to the antenna lead. Is this somehow related to the antenna, or the factory amp?
If anyone can help shed some light on this, I would appreciate it.
Thanks in advance,
