Frequently Asked Questions
What ECUs do you build looms for?
We specialise in MaxxECU, but can build looms for most standalone ECUs. If you’re unsure, just ask — we’re happy to advise.
Do you install the loom or just build it?
We offer both. If installed by us, your loom is covered by our workmanship warranty.
Can you integrate dashes or PDMs?
Yes — we can integrate ECUMaster ADU, AiM dash displays, MaxxECU PDM20, CAN expansion modules and more. That’s only the beginning.
Can you ship the loom to me fully labeled and ready to install?
Yes! Every loom is clearly labeled and comes with a pinout or wiring reference. We can even offer remote support during installation. This is also dependent on the package chosen.
What’s the lead time for a custom loom?
Typical turnaround is 2–4 weeks depending on complexity and material stock. We’ll give you a timeframe at time of booking.
