This van has the radio controls on the steering wheel and the customer wants to install a cell phone car kit that has a radio mute wire that can be hooked up. Does the van have a wire to hook it up to so that the radio will mute when the phone is in use? I imagine that there should be one as there is a mute button on the steering wheel.
Thanks.
try and find that set of ribbon wire that runs from the steering column to the radio. (At least I believe I was told how strg. wheel controls were done - I've never done one before). Find the mute wire in that ribbon, find its polarity and then adjust accordingly.
I wasn't sure if you already figured that much of it or not - and you were just looking for the wire color. But if you were to ask me the wire color i wouldn't know. Hope that helped a little.

What you need to do is create a circuit that will introduce a 475 ohm resistor between the dark blue wire in cavity A7 of the radio's plug and the pink wire in the cavity A6 next to the dark blue wire. This is the same as pressing the mute button on the steering wheel. The first pulse will turn it on and a second pulse will turn the mute off.

Sorry! Make that a 2387 ohm resistor.

The cell phone car kit has a radio mute wire. I just need to know where to connect that wire to.
Other than the circuit I previously mentioned, there isn't any mute circuit for the radio. If your cell phone's mute circuit goes to ground while the phone is in use you could use that to activate relays to open up all four speaker output wires from the radio. There isn't an ignition wire to open so you must break the audio output signal of the radio with relays. You will probably also have to use the mute output wire to trigger one relay which in turn will activate all the other relays as the cell phone's output won't be strong enough by itself.
