Lexus forums weren't much help, so I hope you guys can figure this out. I replaced my stock radio on my 1998 Lexus ES300. The car I have has one of those integrated antennas in the rear windshield.

Anyhow, there are 2 antenna cables that connect to the back of the stock radio. One of them is the standard Motorola Male antenna plug while the other is a shorter fatter version of it. I suspect the shorter, fatter one is the AM antenna. Other than splicing it into the standard Motorola Male antenna plug, does anyone have ANY idea where I could get an adapter for the plug???? Or can they at least provide me with the proper name of the damn antenna plug?

For now, I have just attached the regular plug into my aftermarket HU. My reception is nowhere near that of my stock radio so I assume that hooking up the second fatter antenna plug should make the difference. Any ideas as to where I could find an adapter for this cable?

I did a Google search and only came across the standard fare at the online audio resellers. There are no adapter cables for Toyota or Lexus. Any help is greatly appreciated.

Thanks!
