FAQ
Got questions?
Straight answers from our team.
Will a patch loom void my warranty?
Generally, no. Under Australian Consumer Law, fitting an aftermarket accessory doesn't automatically void your new car warranty. A manufacturer can only refuse a claim if the accessory caused the fault. Our patch looms plug in between your factory connectors with minimal modification, so they can be unplugged at any time to return your vehicle to standard.
Which vehicles do your products suit?
Every product page lists the makes, models and years it's designed for. Not sure about yours? Get in touch before ordering and we'll confirm fitment.
Can I install it myself?
Most of our plug-in looms and harnesses are made for DIY installs with basic tools. For bigger jobs like hard-wired lighting, we recommend a licensed auto electrician.
Will I lose any factory functions?
No. Our patch looms work alongside your factory wiring, so your original switches and features keep working as normal.
