Instead of using electrical tape and silicone, use heat shrink tubing. You will have bare wires so you can get a chose fit. If you can find the extreme environment type heat shrink, use that. It has a gooey inner layer that flows and seals watertight.

When I swapped my sensor (it was dead) I used a Bosch that did not have the correct plug, so I spliced into the Bosch wiring with the old sensor's cable. This gave me an extra 8 inches or so of cable to work with, which is nice later on. No problems, and I didn't have the super heat shrink, just the regular stuff.

If possible, take photos of your installation. I posted mine here like 2 years ago, so don't know if you can find it or not.
