Outsourced wiring harness design
When you have a programme and you do not have a harness engineer, we are the team that gets the design done — on a fixed scope, fixed price, fixed timeline.
Plenty of engineering teams hit the same wall. The mechanical and software sides of the programme are staffed, the harness is the gap, and the gap is in the critical path. Hiring a senior wiring engineer takes months. Going to a manufacturer-led design house ties the design to one build partner. Outsourcing to us solves the gap without making any of those compromises.
We take the harness design programme end-to-end. You write a brief. We come back with a costed scope and a delivery plan inside a week. Then we deliver — schematic, routing, 3D, BOM, spec, test plan — handed over to whichever manufacturer you choose. The phrase we use internally is: brief on Monday, first-pass scope back by Thursday. That is the target on every engagement.
Deliverables and scope
Each engagement is priced and scoped before we start — no scope creep, no surprises.
-
Fixed-scope package
Everything the build shop needs in one pack — schematic, 3D, BOM, spec, test. No follow-up consultancy creep.
-
Single point of contact
One engineer owns the programme end-to-end. Weekly check-in, daily Slack/Teams if the programme is hot.
-
Build-partner neutral
We hand the design to your manufacturer — old, new, or one we help you tender. No build-shop pull.
-
Speed differential
Bespoke in-house tooling collapses routing, BOM and spec generation. Days, not weeks, on the longest steps.
From brief to sign-off
- 01
Brief — Monday
30-minute call. Constraints, target build partner, key dates. NDA in place if needed.
- 02
Scope — Thursday
Costed plan, milestone schedule, named engineer. You decide go / no-go before any clock starts.
- 03
Design — weeks, not months
Iterative releases. You see schematic, then 3D, then BOM. Every milestone reviewable, every milestone fixed-price.
- 04
Hand-over
Pack signed off, delivered to your manufacturer in their preferred format. We stay on call for build queries.
Common questions
Is this a fixed price or a day rate?
Fixed price by milestone, by default. Day rate available for genuinely open-scope discovery work — but we will steer you toward fixed-price whenever the brief is tight enough to support it. It is fairer to both sides.
What is the smallest programme you take?
A single prototype harness with a clear brief. We have built the workflow around fast turnaround, so a small one-off is a fit, not a favour.
What is the largest programme you take?
Multi-harness vehicle programmes — body, chassis, powertrain, HV — coordinated as a single design release. The hard ceiling is engineering throughput, not programme size.
