4x4 Posi-Lok Cable
Chevy/GMC S-Series
  S-10, S-15, Pickup, Blazer, Jimmy

4x4 Posi-Lok replaces the vacuum actuator with a cable operated actuator that puts the driver in control of the engagement from inside the cab. After engaging the transfer case, a one inch pull of the 4x4 Posi-Lok cable connects the right front axle to the intermediate shaft using the shift collar and fork, and 4-wheel drive is engaged! Simply reverse the procedure to disengage 4-wheel drive.
