Features:
After three decades of heat and extreme environmental conditions, the connectors and wires become extremely brittle and fragile and can break. Oftentimes, they break by just unplugging them. This can cause signal loss and prevent your engine from starting.
This OEM+ replacement kit will replace the stock ECU Bosch DME connector.
