Frequently Asked Questions

Q: Do I need an appointment, or can I just show up?

A: All work is by appointment only so we can plan properly and ensure the best results. Contact us by phone or email to arrange a scheduled appointment.
Q: How long does an install usually take?

A: It depends on the project. Simple installs may take a few hours or days, while full rewiring or multi-accessory builds can take a few weeks. We’ll give you a time estimate before we begin.
Q: Can you help with wiring issues in my older vehicle?

A: Yes! We’re experienced in full rewiring, diagnosing no-start issues, rodent damage, parasitic draws, and other electrical gremlins.
Q: Do you install parts I already own?

A: We typically recommend using trusted brands we stand behind, but yes—if your gear is compatible and safe, we can install it.
Q: Can you diagnose electrical problems or no-start issues?

A: Absolutely. We’re pros at tracking down tough-to-find issues and getting your rig back to reliable.
