    Hi ELR friends. I have an unusual situation. I exported my 2016 Cadillac ELR from the USA to Germany and I am having German car inspection issues. I had to change my turn signals to orange and so i added orange turn signal lights to each side and wired them by intercepting the turn signal wires...

    I've searched the GM parts pages, but I have no idea what subsystem this box is related to. Have you seen any information that would identify this box circled in red? Is it missing a cover? Thanks for your input in advance!
  4. Gen1 Fuse Tap location for non-switched 12v

    Generation 1 Volt (2011-2015)
    I'm working on a "smart-home" "IoT" project, and I need to plug a 12v to 3v Voltage Reducer into something that's always on. It's powering something that is normally powered by a coin battery, so I'm not worried about draining the 12v batter in the Volt. Just want some guidance as to where to...

    Electric Vehicle Batteries & Plug-In Charging
    Hello! I just recently purchased the Ebusbar EVSE with the 3 prong NEMA 10-30 dryer plug. However, I'm currently on a rental property and cannot run any new 220V lines or do any electrical modifications. Because the Ebusbar is listed as being able to charge not only at Level 2, but also at...

    Are there any issues with replacing a 3 way switch setup with 15A outlets to use for L1 charging? In my garage I have an existing 3 way switches to control the interior light from the front overhead door and a rear access door. I would like to leave this always hot as the garage door is...

    Care, Maintenance & Service - Chevy Volt
    I've just had the Chevrolet dealer complete the first repair out of warranty on my 2012 Volt. The extended warranty I had purchased with the car expired last month. In August, as preventative maintenance, I did pay to replace the 12-volt battery. The first sign that I needed a repair was the...

    Hi, I'm looking at getting a Volt but typical UK spec has removed the Auto-Dimming Rear-view Mirror! ;( I'm looking at installing a Gentex5 mirror instead. Can anyone help with wiring?

  11. HOW TO: Trailer wiring harness

    Chevy Volt Accessories and Modifications
    Hello everyone! Figured I'd finally get around to doing the trailer harness write up. This is a super easy install, and I had a couple small issues, and I figured out the solution so everything works 100%. The main problem was the main brake light wire, the wire used for the brakes. I tried to...

    Li-Ion Battery, Charging, Mgmt System - Chevy Volt
    I ran into my EVSE J1772 plug a while back and broke it right off. Took some time, but I finally figured out how they wired it, to include the LED for lighting. I've been writing about this in Mods and Hacks, but found this area and decided it needed to go here.. This is just the PLUG, not an...
  13. J1772 Wiring

    Chevy Volt Accessories and Modifications
    The fix is in!!! On the Chevy Volts EVSE, DO NOT CONNECT the Proximity Pin (PP) onto pin 5. It is for lighting the diode or whatever else you want to power with 15VDC. The Control Pilot (CP) on pin 4 needs 150 ohms across it, to ground. You do NOT need the 330 Ohm resistor and switch, though it...
