Factory Stereo Wiring Digrams With Harness View!

If you don't already know about Crutchfields vehicle wiring database, you MUST check it out!! Just go to this link  Crutchfield Vehicle Wiring enter the vehicle info in the search bar. The factory stereo wiring link should show up bellow the search bar. 

 The main page will look like this.

Just enter the vehicle info, I searched a "Lexus" the search resultes should show up bellow the search bar.

Select the link, you should see something like this! I think this is such a great free resource, I had to share it.

Easy Way To Divide Voltage Using Resistors.

If you need to divide the voltage to wire LEDs, or maybe to integrate an aftermarket stereo into a Ford vehicle with a premium sound system. This diagram will show you how it can be done by using a couple resistors.    

Now before you wire anything using this method, you must consider how much current you will need to power your circuit. You MUST use resistors rated at the appropriate "Wattage" and "Resistance" to allow your circuit to function properly. I will provide a link below to a "Voltage Divider Calculator" so you can get a better understanding of the resistors you will need in order to accomplish what you want. If you have any questions let me know.

Turn Cigarette Outlet from Constant 12V Into Switched 12V.

It's becoming more common for vehicles to come equipped with cigarette outlet plugs that don't turn off with the ignition switch. I recently had someone who didn't want his cigarette outlet to stay on all the time, and this was what I did using a standard SPDT Relay.  

This was done on a 2010-2012 Ford Fusion. Under the dash on the left side, above the driver kick panel you will see the small fuse panel. To the right of that there will be a gray harness with a 14-16 gauge Purple/Green wire, that should be the "Switched 12 Volt Accessory Wire". When you test it with a digital multi meter it should read 0 when the key is off, 12 volt in the acc. position, 12 volt in the run position, but should shut off and read 0 during crank. This diagram will work on pretty much any vehicle, the difference will be finding the "Switched 12 Volt Accessory Wire". Most of the time you can find it coming off the ignition switch, but the colors will vary. To note, it doesn't matter what wire you interrupt coming off the cigarette plug, It will work using either wire.

Training a new car audio installer? This is a great tool!!

Thought I would share this awesome find!! I was recently looking for good content to go over with a new installer I am training and found this online. It's a free DC "Circuit Construction Kit". It allows you to add different components to the circuits your creating like multiple batteries, lights, switches, resistors. It also lets you change the different values such as the voltage, resistance, curent, very useful tool!!
