Hello!
I have a situation, I have to have my car compliant by Tuesday and I only have tonight and tomorrow to work on this project. So if I could get some quick help in the most basic way that would be fantastic!
I have a situation similar to this thread: https://www.electro-tech-online.com/threads/relay-required.160143/page-2
I have an electronic parking brake (EPB) line that I need to tap into, here's the schematic:
Basically the W/G line on the EPB switch (rather than going to ground) goes to 0.2v when the parking brake is on and then goes back to 12v when the brake is off (this line is pretty much the switches LED). All of the other lines behave differently and either dont drop in voltage, or drop from 14v to maybe 12v - none drop to ground. This W/G seems to be the most viable given its also part of the system that blocks drivers from watching videos while driving.
The goal: I basically need this line to cut off access to a line that I have wired to the accessories of the car. Thus if the parking brake is on, the device thats triggered by accessories is disabled (no power).
I have tried simply wiring a relay to this W/G line and passing the accessories through it, but this was before I found out that W/G does not ground itself, rather it drops voltage.
Now upon googling this issue I came across this forum and the aforementioned thread.
I have bought the same if not similar components and I wish to assemble this as soon as possible.
The problem then is that I have limited time and thus I cannot just 'figure it out' or quickly learn. I honestly need somebody to show me what to do, to solder what to what etc.
I do know how to solder and in fact do quite a lot of it, but I am not familiar with this type of electronics work, which is quite embarrassing (I do reworking mostly).
Anyways I hope I haven't left something out. I would really appreciate any help.
