Good idea staying with what you have. The issues with the injecter and glow plug harness is they run thru the valve cover gasket. Actually they are a part of the gasket. The wires inside the cover plug into the connection in the gasket. Then the wires outside the cover plug into the connection in the gasket... they crush over time and short out the mess. It was another bad idea using that product like that.
