Frequently asked questions
How do consults work?
Purchase the consult that fits your problem, and you'll receive a booking link to schedule your call. Send your schematics, photos, or ECU config ahead of time. After the call you get a written punch list or action plan within 48 hours.
What do I need to provide for a custom schematic?
Your component list (ECU, gauges, fans, pumps, PDM or relay preference) and any existing wiring info. Standard components are drawn from our reference library; nonstandard pinout research is quoted separately, with your approval first.
How long does a schematic take?
Single circuits ship within a week. System packages and full-vehicle blueprints are scoped on the intake call — typically two to four weeks depending on the build.
What if the diagram needs changes?
Every schematic includes two revision rounds. If we made an error, we fix it free — no expiration.
What systems do you cover?
Holley (Terminator X, HP, Dominator), Haltech, GM LS/LT platforms, OEM module retention, CAN networks, and PDM or relay-based power distribution.
Do you do the physical wiring too?
Yes — full chassis wiring and EFI integration is our core business through Yates Engineering. Remote services are for builders doing the physical work themselves. If you want the build done for you, get in touch via the contact page.
When does the Holley Integration Blueprint launch?
It's in final production now. Join the email list on the homepage and you'll be first to know — v1 buyers get free lifetime updates.
What's your refund policy?
Short version: consults are refundable up to 24 hours before the call; schematic deposits are refundable until drawing starts; digital downloads are final. Full details on the refund policy page.
