2016 ford escape usb and auxiliary power locations?
My mother has this car, but it is the one with the 6" screen without android auto support. I am trying to figure out the most budget-conscious way to add GPS with a larger screen...maybe a stand alone screen instead of a head unit replacement.
Where are the auxiliary power outlets located? I read somewhere that they are always hot, correct?
Does this vehicle have usb ports and if so, where are they located? Also, are they always hot?
I appreciate the help.

How to help
I’m wanting to convert my rig (2018 vw Tiguan) from OEM headlights to light pods and bar lights. Ideally I’m hoping to put pods or small bars in the headlight housing locations (I understand it will need some custom fab and or brackets) and have a bull bar that the larger light bars will be mounted to. Does anyone have an idea how I might be able to do this while retaining full use of factory hi/lo switch as well as good light seres within Baja or Rigid?
Thank you all in advance

Left Headlight Bulb Burns Instantly
Hi, I have a 2003 Toyota ist, right-hand drive. I’m having an unusual problem with the left-side headlight. Whenever I install a new bulb, it burns out almost instantly. The right-side headlight works normally and does not have the same issue.
The left headlight connector appears to have voltage even when the ignition and lights are switched off. When the bulb burns out, the inside of the glass turns white. I have already tried replacing the bulb, but the same thing happens again.
I took the car to a mechanic, and he advised me to replace the steering-column combination switch/headlight and turn-signal stalk. However, I’m not completely convinced that the switch is the cause because the problem only affects the left headlight. I would expect a faulty headlight switch to affect both headlights or cause the lights not to turn on, rather than instantly burning out only one bulb.
The car is a Toyota ist 2003 RHD, 1.3L. Any advice on what could cause this?

1999 Suzuki TL1000S swapped into buggy – fuel pump primes, starter relay won’t click despite start signal
I’m trying to get a 1999 Suzuki TL1000S engine running in a buggy. The engine and harness are stock TL1000S as far as I know.
Here’s what I’ve confirmed:
Battery is good (currently on a booster/charger around 15.5V).
Engine has fresh 10W-40 JASO MA motorcycle oil.
Starter motor is good. If I apply battery power directly to the starter, it cranks the engine strongly with good compression.
Main fuse is good.
Ignition switch works.
Kill switch works.
ECU powers up.
Fuel pump is wired correctly now and primes for a couple of seconds when the key is turned on.
Tip-over sensor is plugged in and upright.
The problem is:
The starter relay never clicks. The starter does absolutely nothing when I press the start button.
I tested the 4-wire connector going to the starter relay with the connector plugged in:
Red: ~15.5V all the time.
Red/White: ~15.5V all the time.
Yellow/Green: ~2.8V normally, jumps to ~15.5V when the starter button is pressed.
Yellow/Black: ~2.8V normally, also jumps to ~15.5V when the starter button is pressed.
I also removed power from the relay and measured the relay coil itself. The copper terminals measured about 4 Ω, so the relay coil doesn’t appear to be open.
The side stand switch is still present. Measuring directly across the switch gives:
OL when released.
About 0.5 MΩ when pressed (which doesn’t seem right).
I temporarily jumpered the side stand switch connector on the harness, but it made no difference.
So at this point:
ECU powers up.
Fuel pump primes.
Starter button is clearly sending a signal.
Starter motor works.
Starter relay never clicks.
What am I missing? Is there another interlock (neutral switch, clutch switch, side stand relay/diode, etc.) that could prevent the starter relay from energizing even though the ECU and fuel pump are working?
Any help would be greatly appreciated. I’ve been chasing this for a while.

LDA doesn't work after plugging in a dashcam
I got a dashcam and used a splitter to divert power from my 12-pin plug (behind the mirror). There should be no power loss, and the LDA system still acts like it's on/working, but it doesn't alert me when i'm close to the lins, or sound off when i swerve.
Where is the sensor for the LDA? is it in the back of the mirror? in the housing ? I wonder if one of the wires is blocking the camera or something

2016 Chevy Silverado Electrical Issues
I have had past issues with the electrical side of my truck. Took it in and had the electrical cables replaced. Now after less than a year, its doing the same thing. Press the brake, the lights dim and sometimes the "Service Stabilitrac" message pops up. Other times, everything is fine and the. I go to turn and the wheel jerks with the same message that pops up. "Service Stabilitrac" the truck has completely shut off on my while merging into traffic on the interstate. Trying to find solutions without having to take it back in and pay out the wazoo to get it looked at. Thanks in advance for any solutions.

Issue with 22 Malibu, ~47k miles
Enable HLS to view with audio, or disable this notification
So this issue started/and got fixed a year plus ago. I would drive my car, then all my dials on my dash
would go to zero like it died, shifter indicator was off so it wouldn't let me turn off my car because it "wasnt in park", I could move it to park but it wouldn't indicate. Lastly it would show check engine like and "Service ESC" message. I had a scanner from amazon which listed error code P0700, something about TCM. Then as fast as it came it disappeared. I took it to the dealer and the light was gone, they said they couldn't do anything as they saw no issue. This happened 2 more times until they finally were able to scan it while the engine light was on, and when it was all serviced I asked what was the issue. They said they just had to put electrical tape on some wires under the shifter area. So that worked well for a year. A month+ ago on an average day I turned on my car and I saw the check engine light, I scanned it and it had code P0641, it said faulty ECM, something about shorting or open circuit. Then that went away. Next week I was driving, gauges dropped to 0, engine light came on, service esc came on, and even traction control turned off. I pulled over, turned off my car, turned it on, and drove back home, engine light still on but it drove fine, error code P0700 again. Then it went away same day. Finally, 2 days ago I was doing 60 on the highway, and my car jolts, I think I hear it downshift, I couldn't really tell exactly what happened since I had music on, but once again gauges dropped for a sec and I pulled over, turned it off and turned it back on. It was fine for a mile, and then I noticed that even going 40mph my car was revving harder that I usually hear it. I make it home, and turn it off. Next morning I go to work, engine light still on, I have been going 35, till I hit a 40mph zone, as soon as I go to accelerate, my revs go to 4k, and after a few seconds I smell something burning, so I immediately go back down to 30, hazards on, make it to work, make it through my day, then decide to take it to the dealership. I have a video I will attatch of how the ride there was, a whole bunch of the same thing but happening back to back. I know it must be an electrical issue but could my transmission also have gotten damaged from what I explained?

Driver’s power window stopped working after hardwiring dashcam on Honda (Slot 1 fuse tap)
Hey everyone, ran into a weird electrical issue on my Honda while installing a VIOFO dashcam with an HK3 hardwire kit.
I tapped into Slot 1 (20A - Door Locks/Windows) for constant power and Slot 19 (20A) for ACC using dual-slot fuse taps.
The dashcam and parking mode work fine, but now my driver’s side power window completely stopped responding.
Symptoms:
• Driver’s window won't roll up or down at all.
• Every other window works fine (passenger window and rear windows can be controlled normally from their switches and from the driver's master switch panel).
• The window briefly rolled down once right after installation, then stopped.
What I’ve tried so far:
1. Tried the standard window reset/recalibrate procedure (holding switch up/down for 5+ seconds) — no response.
2. Checked the master window lock switch — it's unlocked.
3. Pulled the Slot 1 fuse tap for 3+ minutes to reset the door module — no change.
4. Verified the wiring harness under the dash near the fuse box is firmly connected.
Is there a separate inline fuse or ECU relay specific to just the driver's window switch that might have tripped, or does the door ECU need a full battery disconnect reset? Any advice on what to test next would be greatly appreciated!

How to use electrical connections inside of a fuel tank
I’m currently wiring a fuel pump and wanted to use crimp ring terminals and some heat shrink. Do I need heat shrink? if so does it need to specify fuel resistance? The connection will be at the very top of the tank so I don’t think it will be submerged ever.
Any help is appreciated
Thanks
