Wanting to upgrade my base Deville


Recommended Posts

I have a 2002 Deville (Base) and I want to add heated seats And turn signal mirrors. Does anyone know if the wiring harness in the door are the same for the base as it is for the DHS or will I have to change the wiring harness before I add the swithches and mirrors. Anyone with any knowledge?

JimD put the signal mirrors, he will probably stop by. In the meantime search mirrors and JimD and you should find his thread, I think they plug right in..

OK! I got my mirrors installed, but the signals don't work. My old mirror had one plug onthe end that plugged into the door controller, the new ones have three. The first plug I just replaced with the existing, the second plug fit into the spare spot on the door controller, the third I'm not sure. It's the small plug (One wire blue and the other black/white). Any suggestions?

The first year for OEM turn signal mirrors (Deville) was 2003. You cannot expect an earlier year model to have the required OEM connectors or signal voltage available at the door chassis wiring harness.

And the instructions provided regarding the modification of my '98 Seville mirrors do not apply to Deville models.

What you need is a convenient place to tap into the turn signal voltage and that would be your front turn signal lamps. You need to snake wires from the front lamps to the respective door mirrors.

Then, you will have to fabricate some means of connecting that turn signal voltage to the mirror LEDs. I appreciate this is not a chore for folks who do nat have an extensive electrical background and a well stocked junk box of electrical parts/pieces.
