Many thanks My background in electronic components is minimal; however I think I am able to follow your instructions. Certainly I will not be able to construct (myself) any ultrasound transmitter/receiver but I may order an already made ultrasound receiver to be located in the rear bumper. I...

May I kindly ask you to provide your comments (e.g. Pros, Cons and Workability) of the approach suggested by our member (Jim Hardy)?

OK I understood the inability of the sensor wires of carry enough power to light the LEDs. Will the power of the pulses DC be enough to drive a miniature relay?

(Pulse signal, 0V-8V, 40 kHz pulse signals, emitted approx. every 125 ms) Making sense of the statement above in addition to your description of how the signals are transmitted to the sensor heads (rear bumper) I may say the following: The corner/back sensor ECU has 20 pins and only...

I would like to comply with international regulations about rear fog lights on vehicles and this requires that rear fog light can only be activated when the dipped beam headlight is ON, not without it. I know I have some gaps in my thinking to fully understand the electronic behavior of LED...

Many thank for your comments I am conversant with Ohm’s law and Kirchhoff’s law so I understand your DC calculations. I have also found some information on the web where PDC is used to drive LED (experimental stage). There is also a company that produces LED lamps driven by PDC. I would...

After finding out that connecting 12V, 25 Watts bulbs into a PDC (8V) source will produce catastrophic results in my vehicle, it has come to my mind, just for curiosity, what would happen if LED (light emitted diodes) were used instead of filament /incandescent bulbs? Diodes may work with 3V-5V...

There are some subtle drawbacks with running a wire under the carpet floor, refastening and re-clipping it, hole drilling, and putting the protector detached panel (quarter trim) back in place. By experience I may said that the auto electrician is most concerned in bringing light to the rear...

Many thanks for your comments. You have scared me! OK what about this approach: 1- The corner/back sensor ECU activates 4-wires with pulsed direct current, i.e. 1-sensor corner LH, 1-sensor corner RH, 1-sensor back LH, and 1-sensor back RH 2- I will cut the 2-sensor corner wires LH & RH...

and it's rude to burst into a thread! I am very sorry. It was not my intention. Just I thought the topics are related and why to open a new thread to talk about similar subjects. Sorry again Using your formula the 25 W bulb will light with a power of 11.1 watts which I think is not "so...

The final manipulation of the details will be done by an auto electrician. My main concern rests into finding out if the approach is physically/theoretical feasible. If the approach is feasible, then I will discuss the details and the proper use of tools to do the job with the expert. I have...

I am able to locate a 12V wire under the car’s console. I will branch it into 2-wires to match the 2-wires PDC and prevent any over heat that may happen in the carrying wires until they reach the rear of the car. So each wire will light a 25W bulb.

Many thanks I do not want to cut the 2-wires (under the car console) that carries PDC to the rear sensors and solder 2-wires 12V to them and thereafter using the 2-cutted PDC wires to carry 12V current under the car floor harness. Questions: Can I just solder the 2-wires 12V onto the...

Hi, I am new to this forum and I hope someone will give direct answers to my query. 1- I have 2-wires that carry pulse DC to 2-sensors (parking sensors). The car’s ECU converts 12V car battery current to 0V-8V PCD (40 KHz pulse signal, emitted approx every 125 ms). 2- I would like to...
