Question:

Is this a plug and play project that doesn't require rewiring?

No. There are considerable differences in the amplifier and head unit.

Including the head unit and amplifier plus all speakers.

But stock pioneer CD changer.

I'm pretty sure you need the nak wiring harness

mayad79

How can I be sure of what I need. Would a wiring diagram help me?

Probably not. Moving from one level of factory stereo to another is always a challenge, such as when moving from an internal to external amp. If you really have your heart set, anything can be done, yet it might mean acquiring a complete harness, then removing most of your interior. The amp is in the trunk right/rear, has a woofer, cd-changer, etc. Anything can be done, yet this is a lot of work.


Does anyone (such as Metra) offer color-matched trim for double-din stereos?

As I am parting out a 1998 Nakamichi equipped car and I have someone who wants to do just this changeover. It'll be interesting to understand the ins and outs of this swap.

The last GS400 I parted out was also a 1998 and had the pioneer unit, but I do remember the audio harness was separate from the rest of the electronics (Except the door sections).

I'll document the dismantling process and see how much work it is.

If the harnesses are really that independent, then awesome. My experience with radios has been with Toyota internal vs. external amps, and those harnesses (for the years I'm used to) is integrated in to the harness... adapting is a mess, if at all possible. If Lexus made the radio harness separate, with minimal connections for interfacing to the rest of the car, then very cool.

I just dread pulling the seats and carpet (and door sills, various trim, etc) to get to the harness. ('d prefer someone buy the seats and carpet FIRST...

I recall what appeared to be two, antenna wires (I believe one had a co-ax style end on it) running side by side along the trans tunnel, from below the radio stack.

Update: pics are on my phone and my data cable is in my truck, so pics will wait for now.

From the Radio/AC control stack, The AC/heat controls are bound into the same harness. So, they will come out together. This seems to be all plug and play and I have everything undone there. From there the harness runs into the center console and runs back.

From the back (The amp as you all know is in the right rear corner of the trunk) the harness is only connected to the amp and runs forward to the right corner of the rear seat and attached to the seat cross brace.

From there it runs forward, and splits just under the passenger side, forward corner of the seat bottom.


As I haven't pulled the seat, but did pull the moldings and sill plates I was able to see that the harness appears to loop around into the forward harness connectors, passenger side B pillar connectors and probably the power seat power.


Anyone in Hawaii looking for 2GS parts so I can throw this away soon?
