Just got done installing these; hi-z 1680's and the modified resistor pack connector that I soldered all the wires together. I haven't started it yet because I can't find my zeitronix wb connector that I have to solder back to the ecu connectors, without it my ecu gets no o2 feedback at all because I'm only running my zt-2 fed into the ecu with narrow band simulation and eliminated the front and rear o2 sensors.
