Installing an after market radio in a 1995 LS 400 (HELP ME!!!!!! PLEASE!!!!!)
Would someone please tell me or show me the wiring code or diagram for a Lexus Nakamichi Sound system. I’m trying to put in an aftermarket radio in a Lexus LS 400 1995 and I would like to know each wire color code including how to make my power antenna work with the after market radio if possible. Primarily I need to have all speakers functioning less the center sub woofer with the after market radio. 
"Please can someone assist me????"

I just used the cut one and test method. I removed the faatory amp from under the passenger seat and using a ohm meter check the wires continuity and also did the same with the wires for the speakers......takes a long time but I got it done. Works like a champ!!! I have a pioneer DEHp- 9300.
It was one of the hardest installs I have done.

even with the metra harness i do believe you will lose functionality of the rear sub.
and if u decide to replace the rear sub with a full system pleae let me know, il buy the Nak sub off you.

When I go to that site for the purcahse of that unit, It dosent give me the option for my vehicle (LS 400 1995). Which unit I get for my vehicle. Im not using the center sub simply because Im installing a whole new sound system in my vehicle. I just want the after market radio to have access to all 6 standard door and tweeter speakers. As far as the factory center rear sub, I don't have that any more because that speaker blew on me about a year ago. I've installed an after market sub that would be support by and after market amp.

(UPDATE) I just called metra VIA telephone and they don't carry a radio after market harnest for my vehicle (LEXUS LS 400 1995). 
I need help guys! I want to install this after market radio but don't want to cut and search for the correct wires to make it work. A harnest would work perfectly. Can someone tell me which color is the battery positive (12V) for the radio? When I turn on the vehicle, I should be able to turn on the unit. And when I turn the vehicle off, it should go off as well automaticly like the factory and not lose any memory. Which color wire supports that ?

I will make a call to my distributor they just came out with a brand new one for the 93 that was great easy and just simplified the system all it had was red, black,yellow, 1 remote, 1 power antenna and 4 pre outs rca's and was told they were going to do this in the 95-00, 2 months ago. it might not be available for retail yet. and yes you lose factory sub must put in aftermarket amp or splice but if you splice you lose all eq for sub

I've seen that harnest before and I was told that it wouldn't fit mine because I have a Nakamichi system which is a 14 pic connection. The harnest you have on display is a 15 pin connection.
You are the man though for trying to help me get the information I need
. I really appreciate it man but I don't know what I'm going to do now

more than likely ur juss gunna end up elbow deep in the dash soldering/crimping by hand. nobody makes a WIRING kit for our cars but hey, isnt custom wiring cheaper than a custom dash kit. GL
