Hi Keith
The harness seems to go straight into the cab just above the fuel tank.Thanks anyway.

Hi
The new additive pump needs to be configured to the ecu, I have had the same fault I tried to code it with my snap on solus but didn't work, but the customer took it the dealers and they coded it in for him.

Thanks
