Default 1993 Lexus LS400 Double Din Install Help Needed

I just ordered a double din stereo for my 1993 Lexus LS400 that normally had a oem pioneer sterero.

From what i understand i need to order a Metra dash kit for the double din to sit flush.

Has anyione installed a double din in the first generation LS400? What do i do in terms of wiring, i dont believe it will be plug and play. Is there a special kit to order? From what im reading you may possibly lose subwoofer function. Some are saying to order a beatsonic kit but the price is ridiculous at $250.

Would this kit work? It has an Amp Integration Wire Harness:

OR would this work:

Any tips would be appreciated.

I am uncertain myself which is the proper piece offhand but Metra has four harnesses (70-1761, 70-8112, 71-1761, 71-8112) that appear on their website as compatible with the 93 LS400.

But it is quite simple to hardwire the radio harness directly to the factory harness. A DMM, a speaker tester and about 20 minutes of time will help you identify all the wires in the harness.

This information from modifiedlife.com will assist in locating wires behind the dash:

1993 Lexus LS400 Factory Radio Wiring Chart

Car Radio Battery Constant 12v+ Wire: Red
Car Radio Accessory Switched 12v+ Wire: Gray

Car Stereo Amp Turn-On Trigger Wire: Pink/Blue
Car Stereo Amplifier Location: Right Side of the Trunk

Car Audio Front Tweeter Size: 1″ Tweeters
Car Audio Front Tweeter Depth: 1″
Car Audio Front Tweeter Location: N/A

Left Front Speaker Positive Wire (+): Green
Left Front Speaker Negative Wire (-): N/A
Right Front Speaker Positive Wire (+): Red
Right Front Speaker Negative Wire (-): N/A

Car Audio Front Speakers Size: 5 1/4″ Speakers

Lastly, if you have some good install and 12volt experience you can go directly to the amp and grab all wires there in order to ensure retention of the sub.
