Installing the Chrysler Electronic Voice Alert 11 Function Unit
This page will conver the installation of an 11 Function EVA into a Mopar vehicle that was not originally equipped with an EVA. The donor car was a 1987 Chrysler New Yorker. This page is far from complete, but still offers good information. I will be updating this page as I work on this project.

*** In non EVA cars, the "headlight on" and "key in" chimes both use the light blue wire. When installing the EVA, I disconnected the light blue wire from the headlight switch so that only the key in switch used the wire. I connected a wire from the headlight switch (where the light blue wire was connected) to EVA plug 2 pin 28.
