Adapter Gauge Panel GM 34-Pin

The Adapter Gauge Panel GM 34-Pin is a precision wiring harness interface designed for classic and vintage General Motors vehicles requiring modern instrumentation integration or factory gauge cluster restoration. Built by NEW VINTAGE USA, this adapter panel bridges the gap between OEM GM electrical architecture and contemporary aftermarket gauges, making it indispensable for restomod projects, engine swaps, and custom dash conversions.

This adapter harness features a 34-pin male connector that matches factory GM dash clusters from the muscle car and classic truck era. It simplifies the wiring process, allowing for easier integration of modern gauges and warning lights. The precision-molded connector body ensures reliable signal transmission across all gauge circuits—oil pressure, fuel level, temperature, charging, and warning lamp signals—without voltage drop or intermittent failures.

Restoration specialists and engine swap fabricators will find this adapter harness particularly beneficial, as it aids in preserving original functionality during restorations. Weighing just 0.31 lbs and measuring 6 x 2 x 9 inches, the panel mounts cleanly behind or alongside dash clusters, protecting vulnerable connections while remaining accessible for service diagnostics.
