Which temp sensor did you change out? The 1-wire guy is the one that runs the cluster. The colored 2-wire runs the ECU. If you have an external temp gauge, you can try to mount the sensor in place of the factory 1-wire. I'm not sure how big this thing is, though. The other popular location is the coolant neck on the outlet side. The material is thick enough to drill and tap. Don't forget that you can read the ECU's temp sensor with a consult interface!
