Finally got around to installing this kit for the wife, did the back 4 sensors, and installed the front, but need a tap for brake lights. I pulled the connector off the brake pedal sensor, probed the 4 pins, blue is 12V+ all the time, red is 12V when pedal is pressed. Plan was to pull the pin out of the harness plug and solder on a wire to run to the black box for when the brakes are applied. Man, I am familiar with unhooking pins from a harness, but this one is giving me fits. I used both a small flat jewelers screwdriver and micro picks to release the tab, but not having any luck. From what I can see, which isn't much contorted under the dash, it's should be just press the pin tab down, pin should slide out plug. Any tips?

I make my own pin remover by modifying a jewelers screwdriver, mainly making it thinner and less tapered. I wonder if there is a kit out there, anyone know?

When trying to look up a schematic on that plug I saw they do make a tool for that and instructions how to make your own. I'll try to find it again.

edit- There's a whole section on the various plugs used by Toyotas, about midway down from this link- Camry Electrical Diagram

They do make tools for this, even sets. Google " terminal pick set" or "Terminal Release Tool"

After getting after it again, I saw I was trying to release the metal tab, when I should have been releasing the plastic tab in the harness.
