Moved onto wiring up the injectors today, removing the stock Denso plugs and fitting the Bosch ones.
Cut the Denso plug off.
Stripped back some of the plastic sleeve, fitted the rubber seal, crimped and soldered the pins on.
Pushed the pins into the Bosch plug housing.
Slid the seal up over the plug.
Then plugged them on.
Next up will be to play with the fuel pump setup and find a place for the flex fuel sensor to go.
