    My buddy handed me a DFO (same as TFI) unit today and said give this thing a try. The only problem is it dosent have the plug and play harness just 4 wires,red black gray and blue. I assume the later goes to the injectors. I dont want to carp up the stock wiring but how does this thing hook up?

    Ok sounds like sound advise. Should I get the TFI instead?

    If this is a Rev Tech product and I am pretty sure it is I would opt for something better JMO:s
