Custom Schematic — System Package

Three to four related circuits, engineered together.

What you receive

A coherent documentation package for 3–4 related circuits — typically complete engine-management support: power distribution, grounding, fuel, and cooling. GM service-manual drawing style with full connection tables for every circuit. Two revision rounds included.

Who it's for

Builders wiring a complete engine-management install, and fab/resto shops that build brilliantly but hate producing documentation.

Problems it solves

Circuits designed separately fight each other — double-fed relays, overloaded shared feeds, grounds that sneak onto the wrong side of the car. Designing the set together means feeds, grounds, and relay/PDM assignments actually agree.

Time & mistakes saved

The coordination errors between circuits are the ones that surface at startup and take days to trace. This package removes them on paper, before wire is cut.

Ordering & scope: 50% deposit at order, balance before file delivery. Nonstandard pinout research, OEM module reverse-engineering, and undocumented components may require additional quote approval before work begins.
