OK heres the deal. Im installing MIcrotech Lt8. Im trying to remove the stock ecu and harness. The passanger side harness, the one you remove bridges once inside the car by the wire wall. Looking straight at the ecu, up to the right the harness octopuses to a couple of sensors and such. Doe these need to be hooked back up what are they?

 

i belive you're talking about the wiper motor harness and some other random plugs.

 

another thing. Driver side harness comes in and hookups to the ecu Do i cut that connector off when i go to install the ECU?

 

No, you can leave that.

The ECU harness branches off for wipers, and Knock Control.
