Easy installation thanks to the video. I went a step further and used split-loom plastic wire protector to protect the wires running through the engine bay. This gives a neat, factory look. I opted to remove the battery and the battery tray to run the wire along the existing wire loom. Extremely happy with the final result as these add to the car being visible to other drivers.
I had some issues with my DRL switchback light kit(which could happen with any electronics) and the SC430mods crew took care of me. They sent me a replacement once I verified my issue with a video via email. Great people! Will be buying more items from them!
Love this update. Makes the car look newer. Had a wire connection issue, but tech Savy Henri walked me through all of the possible issues and was right with the process of elimination. Purchase with confidence, either video from Calvin or Henri will make installation easy. And any issues you run into Henri gets back to your email ASAP. Plus Calvin backs his products with money back guarantee or replacements sent out the very next day.
I have a right hand drive 2004 and am struggling to get installed. Tried once and gave up after failing to get the wires though to inside the car. Will need to look again but firstly need to know if right hand or left hand side entrance through bulkhead.
