I have a 04 GS430 with the Mark Levinson navi and stereo system. I am trying to put in an aftermarket double din dvd cd navi system. I do not want to cut the wiring harness and I've searched everywhere to find a wiring harness, but there is no harness for the Mark Levinson stereo system. Is there a way around hooking up an aftermarket system without cutting the wires? I do not want to hook up the stock amp and sub. I am going aftermarket on that as well. I was wondering if I can custom make a harness by opening the radio up unsoldering the pins in the radio and solder the aftermarket radio wires to that.

 

You can get a generic harness for Toyotas with amplifiers (the single plug, not the common two plug non-amplifier kit), which will fit the plug in the car. All you would need to do would be to figure out the battery, accessory, and ground wires coming off of it.

 

 

These are the clips for the radio. The generic Toyota harness that I found didn't work. Where did you find the harness your talking about?

 

Does anyone have a spare Mark Levinson radio? I don't need the navi just the radio. It can be broke. I will buy it off of someone.

 

Something like . Just disregard the co-ax plugs and use what you need. Desoldering the connectors from a factory radio is much more trouble than it's worth. That other plug is for the steering wheel controls, which won't work with an aftermarket radio anyway.

 

Awesome info I'm gonna try that. Thanks!!
