Glow Plug Relay Connector for 6.2L/6.5L Diesel Engines
GM used two variations of this connector: a black, 4 wire connector and a gray, 3 wire connector.
The black 4 wire connector is used on all 6.2 liter engines and most 6.5 diesels that utilize a mechanical injection pump. If there are four terminals on your glow plug relay and the connector is black with 4 wires, this is the correct replacement for your application.
The gray 3 wire connector is used on most 1994 and newer engines that utilize an electronically controlled injection pump. If there are three terminals on your glow plug relay and the connector is gray with 3 wires, this is the correct replacement for your application.
Black and gray connectors are not interchangeable and will only fit their intended relay. Please select the appropriate connector above before adding to cart .
