Original Engine Management 89010 Neutral Safety & Reverse Light Switch

Getting rid of the GM electrical connectors on the old switch was the most challenging part of the install. It would appear that GM uses an entirely different locking tab for every single connector in their cars. My original switch had an extra spade connector that was not present on this There is only one way to get there. Neither the right way nor the wrong way can be done. It was a matter of rotating and checking the alignment twice, and the B/U lights came on when they should have. If possible, you should perform the installation after dusk with your vehicle parked in front of After you adjust the thing (rotate one way or the other) you'll be able to see when the B/U lights are on without having to walk back to the unit. In order to adjust, block the tires, set the eBrake, turn the key on but do not run the engine, and put the gear selector in reverse. The B/U lights can be turned on by rotating the plastic thing one way or another until they are turned You are now done. Simply run the gear selector through its range a couple of times to be sure they come on as expected and you are all set. Even when you have something else under the steering column, such as an alarm or sound system, you won't need to take out the trim piece under the steering column. If you have to remove the plate, it only requires the removal of four to six screws, nothing critical or difficult. You should take a flashlight when you remove the old and install the new under the dash. The ground beneath Phoenix is dark at noon even in the middle of the day. An old switch can be easily removed from its mounting position by using a small flat blade screwdriver.

The following is a review of what Amazon suggests a 1981 GMC C1500 should be like. There is no fit for this part, as it looked like it would. Wire harness is not connected to the mount because it is a different mount.
