    All engines

Designed for compatible 1967–1972 Chevrolet and GMC C10 pickup trucks. Verify your exact model year, cab configuration, drivetrain, and original electrical layout before ordering. Confirm compatibility with your steering column, ignition switch, gauge cluster, alternator, starter, and charging system. Trucks with LS swaps, aftermarket EFI, digital gauges, custom lighting, electric fans, or other modern upgrades may require additional wiring or adapters. Check whether your truck retains the factory firewall opening and bulkhead connector location. 2WD and 4WD applications should be verified against the manufacturer’s fitment guide. Factory air conditioning, aftermarket A/C systems, power accessories, and added electronics may require extra circuits, relays, or connectors. Vehicles with heavily modified dashboards or non-original steering columns may need installation changes. Confirm grounding points, fuse requirements, and accessory circuit loads before final installation. Professional installation is recommended if you are not experienced with complete vehicle electrical rewiring.

The 28-circuit system offers flexibility for accessories, but electric fans may require properly sized relays, fuses, controllers, and wiring depending on their current draw.
Can I connect aftermarket gauges to this harness?
Yes, in many builds, but the gauge wiring must be adapted to the specific gauge manufacturer’s requirements.
Will this harness work with the factory gauge cluster?
It can support compatible factory-style gauge configurations, but exact connections should be verified against your truck’s original cluster and the installation manual.
Does the kit support air conditioning?
It can support compatible A/C-related electrical circuits, but factory and aftermarket air-conditioning systems may require additional wiring, relays, or control connections.

Complete Painless wiring kits generally include many of the required terminals, connectors, and installation components. Verify the exact part-number-specific contents before purchasing.
Does the kit include installation instructions?
Yes. Painless complete harness kits typically include detailed installation instructions and wiring information to guide routing and circuit connections.
Do I need professional installation?
Professional installation is recommended if you are not experienced with complete vehicle electrical systems. Incorrect wiring can cause electrical faults, component damage, or fire risk.

Installation is a substantial project because the truck’s major electrical systems must be routed and connected. Circuit labels and color coding simplify the process, but careful planning and electrical knowledge are still important.
Should I disconnect the battery before installation?
Yes. The battery should be disconnected before electrical installation work begins and should remain disconnected until wiring has been inspected and is ready for testing.
Can the harness be modified for custom builds?
Yes. Custom vehicles may require modifications for aftermarket engines, gauges, accessories, lighting, or steering columns. Follow proper electrical practices and the Painless installation instructions.
What should I verify before ordering the Painless 10206?
Confirm your truck’s exact year, Chevrolet or GMC model, drivetrain, steering column, ignition system, gauge cluster, alternator, engine configuration, lighting setup, and aftermarket accessories. Final compatibility should be verified using Painless Performance’s specifications for part number 10206.
