LX470 On-board Air

After the drawer system was done, I felt that the rig could use a compressor system. I had a couple of components for air at home so I set out to plan for that. I wanted to utilize the space under the flaps on one side just to maximize space so set out to do that. 

First I laid out the tank and compressor to see what works best as far as layout, clearances etc. 




With the measurements of the components in place traced out the floor and the sides. This would make it completely removable and going to integrate the straps etc. to hold the onboard air in place as well. Pics below shows the platform I came up with.





The platform was clearanced and fits perfectly under the flap.




With the platform clearanced, positioned the compressor and tank for it's final location.  




The mockup and mounting of components. Created a wiring harness utilizing a switch, a pressure switch, a relay and an automatic reset trip fuse. I wanted the setup to work only when the car is on and the switch is on as well. When the tank reaches 150psi the pressure switch turns the compressor off, when the tank falls to 120psi the pressure switch turns the compressor on. All the wires are soldered, heat shrunk where needed and used tech flex to clean up the wiring. 



There are three wires to unplug and the whole unit is removable. Power, Ground and ignition trigger.




All the components mounted.






Dismounted everything and then carpeted the platform to match the drawer system.




Platform carpeted and everything mounted.







This is the other end of the harness that will get wired to the car. 




Unit mounted and strapped down using the same straps holding the drawer system down as well. 





Used one of the tank holes to mount a pressure gauge and another with a safety coupler to attach an air hose and fittings.




Everything fits nicely under the flap. 






 
Happy with how everything turned out.

LX470 Park Light & Turn Signal Light mod

 This might be pointless to some but I didn't like how the top corner lights was just park lights and the turn signals were down next to the fog lights. I was going to upgrade the headlights and fog lights to white and I wanted the park lights in the corner lights to be white as well to match. At the same time I wanted to use the corner lights to be amber turn signals as well and the turn signals in the bumper next to the fog lights to be amber turn signals and amber park lights. 


To start I wanted to clean up and smooth out the fog lights which was definitely showing its age. Sanded the fog lights using 600, 800, 1200, 2000 and then got them cleared using PPG's 2K Clear.





With the fog lights looking fresh, I ordered the clear corner lights as well. 



The fog lights and the corner lights from factory come with a two pin connector. For what I want to accomplish the two pin connector needs to be converted to a three pin connector to use a dual filament bulb. 


Parts List:
For the socket that goes into the corner lights and the fog lights:
Toyota part: 90075-60060 x 4
For the connectors to go into the sockets you can either go OEM: 
Toyota part: Housing connector (3 Prongs): 90980-11020 x2
Toyota part: Terminal Repair (for insert into housing connector) - 82998-12440 x 12
OR
Aftermarket Toyota style connector: Corsa-technic - TS090-3S-6
Bulbs needed:
Light Bulb (Dual Filaments): Sylvania 7443 x2
Switch back LED: 7443 x 2

Now to test and note what control what on the connector. For this I just used a 12V battery to power and test the connectors.







Below is the wiring schematic for the connector.




With the schematic figured out, I created a harness to integrate into the factory wiring. Everything is soldered, heat shrinked and used techflex wire loom for a clean look. 





The white wire coming out of the harness I made goes to the park light side trigger of the harness. This white wire I spliced into the green wire which is the park light signal on the factory harness. The yellow wire on my harness goes to the the turn signal side trigger of the harness. This yellow wire gets spliced into the green wire on the factory fog light harness. The ground black wire from my harness goes to the white and black wire on both ends of the factory harness. 





I left the factory connectors and wiring in place just incase the mod needed to be reversed. All the wiring was soldered, heat shrunk and taped up where needed.





This is what it looks like with the park lights on now. White up top and amber at the bottom.  






With the turn signals on, both top and bottom blink amber. 




Happy how it turned out, now I just need to figure out what I want to do for the headlights and fog lights.
