While I was modifying the entire taillight wire harness, I integrated a wire extension for the...engine bay light. I will detail my modified tail lights later in a new thread but in a nutshell, the initial idea of Anders was to have all 4 tail lights on (position lights and brake lights all on). From this idea, I developed a modification using a Reed relay and an entire harness upgrade. But for now, back to the engine bay light
In following pictures, you can see how from the taillight wire harness I added a new connector (picture 1) on the LH side, then wired up to the front of the engine bay following the existing main LH side rear
harness (wires are isolated in a thermal protected conduit).
There, I added another connector which can be easily accessed :
This connector makes the link with the SMD Led
strip which is glued directly on the black part of the engine bay window.
When glued close to the edge on the black part, the LED
strip can't be seen from outside and light is directed only on the engine. I used a SMD3528 LED
strip, waterproof IP67 and heat resistance up to 85 degrees Celcius. Power consumption: 550mA. Size: 700mm (approx) x 10 mm x 2 mm
For those who want to dim or switch off/on the engine bay light with a remote control, here's a 12V LED
dimmer I installed (very cheap).
The frequency of the remote control is 433Mhz which is perfect for a car but may disturb some radar detectors (for the US). Installation was very easy as I forcasted this already in my new rear
wire harness. Works very well as the brightness can be remotly adjusted
(useful when reversing for instance).
Despite the engine bay heat, the LEDs are not heating at all and are holding up perfectly well after having installed this mod since now almost 1 year. Glued on the upper part of the engine bay window (on the black opaque part) is the best area as this area remains cool enough to not damage the LEDs.
