No, you don't have to rely on wire colors to figure out what's what. With nothing more than a decent multimeter and premix flame (blowtorch or gas stove), a two-test sequence can reveal the identity of each wire, assuming the O2 sensor is fully-functional: Determine the heater wires This should be done first. These wires serve to heat up the O2 sensor ...

Corrosion on the terminals is due to hydrogen gas being released from the acid in the battery. It mixes with other things in the atmosphere under the hood and produces the corrosion you see on the terminals. Generally, if the corrosion is occurring on the negative terminal, your system is probably undercharging. If on the positive side, it is probably ...

I took my car to a different VW shop (not the dealership) and they fixed the problem for $160, but if I'd known the solution was just to solder the wires directly together, I could have fixed it myself. I did however, learn what the problem was thanks to them and I'll share the solution here. VW apparently knows about this issue and supposedly offers special ...

Just replace the injector plug. I believe it should look like this: You can order it from RockAuto.com for ~$6 (I'm sure you can get it from many other places as well. I would soldier this in place using heat shrink to seal them up. As far as the gaskets go, your vehicle uses the gaskets with the rubber-ish sealing portion (don't know what they are made ...

In this case, the phone is only used as a conduit or a means by which the stereo acts as the mouth (speakers) and ears (mic) through the bluetooth connection. You'll have to hook up the microphone in order for it to work, because that's what the stereo is expecting. My suggestion is to find a spot which is innocuous and run the mic to that spot. It should ...

A quick Google search resulted in this. I couldn't find the legend for it but I guess it should be fairly straightforward. It could be bad wiring, bring out the multi-meter! EDIT Here's a link to the COMPLETE SERVICE MANUAL . It's in German, so you may need to use a translation service .

The diodes should work, but be aware that they will drop ~0.7V or so, so you'll actually get ~11.3V instead of 12V. If the radio is okay with that, and if you can dissipate the heat caused by the diode drop * current drawn (may be small, but must be known), then you're okay. It won't backfeed either source. If you don't want the voltage drop, then you can ...

Looking at the diagrams, it looks like each lock has a motor and a microswitch to tell if it's locked or unlocked - presumably so you can't try and lock it when it's already locked or vice versa, or simply to reverse the polarity. The wire going directly to the motor (red and black) will be common to both. This wire will be positive for one action and ...

Finally got a chance to mess around with it and confirmed an answer I found. All the blinker lights have to be connected in order for it to blink. Connected them all and now everything is working with the blinkers!

The "default" speakers in your car should be bi-wired ones. The 6-speaker layout in your car should have 2 speakers in the front, 2 tweeters in the front and 2 speakers in the back. The speakers in the back of your car should only have 2 strands each. The 4 strands of the connector on the front speakers are composed of two strands for LF - low frequency (the ...

absolutely DO NOT replace a BALLAST with a RELAY. They perform different functions completely and are in now way related. Relay = Switch Ballast = Current Regulation A solid state relay may have some voltage limitation attributes but you need to be sure that it matches the ballast that will be provided with your HID kit. I HIGHLY recommend you use ...

If you pop off the trim and look at the wires, the two twisted together will be for the speakers. The power locks and windows will all run straight. Twisting speaker wires together helps with interference noise and is done on ford's. From factory.

So I did some digging and managed to find a PDF of the entire wiring diagram for the 2014. I'll post a OneDrive link below for anyone who wants to download them. They also contain dashboard disassembly instructions and whatnot. Amp Location: Right side of trunk. If you have the amp, it seems that the speaker wires are the same colors there as in the front ...

Most manufacturers tend to be fairly consistent with their stereo wiring, so it ought to be the same as other modern Fords. A quick googling reveals This site, which suggests the following: Power Memory (+12v Constant) Green Yellow Ignition (+12v Switched) Yellow/Black Ground (-) Black or Fat Red Illumination Orange ...

As they are 'pencil coils' on your vehicle, you can transfer the supect coil on to a differant plug. If the coil now works correctly whilst the one it was swopped with starts to 'misfire' on number three plug then you know you are dealing with a fault with No.3 cylinder. Secondly try replacing No3 spark plug with one you have removed and know to be working ...

The purpose of the resistance in the plug wires is there so that the (1) plug firing voltage is great enough to maintain a sufficent spark firing time and (2) the resistance suppresses interferance with electronic equipment and radios. Spark plug wires are easily broken internally when being removed from the plug, as they can become attached to the spark ...

Turns out the ignition switch was bad. It was causing the blower motor to stay on even when the ignition was in the "off" position. Fixing this stopped the car's blower motor from running when off, then it was as simple as replacing the resistor once more and haven't had any problems for months.
