IF in fact you are replacing the turn signal unit completely, there will be a wiring harness with the proper plug attached to the new one. So don't be scared to just cut the plud off the end of the harness after you unplug it from the cab harness. Then just pull the wires right up and out with the old signal switch. Replace it by just folding the new plug on it's side and feed it down through the housing. Plug it in and put the switch back together.

How to remove turn signal wire harness


New set will have a plug on it so don't be concerned about just cutting the plug off to get the old harness out. You have to remove the steering wheel and anything above the turn signal switch to give access to the little pivot bolt the switch is mounted by. Remove this pivot screw/bolt and pull the unit out. After the plug has been cut off the end of the signal harness, the wires will come out easily. Put all that aside, grab your new turn signal unit, Turn the plug on it's side, flat on the wires, and feed it down thru the column housing until the new switch is in position to bolt back on. Now put it back together in reverse of removal.

95 chevy suburban- brake lights not working (turn signals work and regular lights). checked the bulbs and whatnot- cannot find the problem. someone please help!


There are a couple of types of switches but lets assume you have a more common one. It will be located on the left side of the brake pedal shaft it is black with 4 wires in one connector and a seperate 2 wire connector above the 4 wire connector. The switch is easily removed if it is this style by pulling it down it has 2 clips one at the top and one that slides over the pedal shat the back of the switch has a rased hump tha slides into a recess on the upper pedal support bracket.Grab switch pull down and gently wiggle it if necessary.Remove 4 wire connector and 2 wire connector. Now you are holding the old switch and yor troubles have just started the after market replacement switches really **** get a real gm swich.If you look at the old swich at its bottom you will see a little foot sticking out of the base of the swich once the new swich is installed you must use the little foot to adjust the swich.If you do this wrong you will do dammage to your transmission.The two wires at the top of the swich go to the transmission torque converter clutch.when the brake lights are on the upper swich is off. When brake lights are off the swich will be on.Get new swich installed using this info and get a pro to help you adjust it.It should cost you only 35 bucks to get it set.Dealer shouldnt charge more than 30 bucks for switch.

    Changing turn signal switch on 93 oldsmobile cutlass supreme


    Removing the turn signal mechanism from the steering column is easy and can be accomplished in under a half hour. First you should remove one of the battery cables as you should have no power available when removing or installing the wiring harness.then remove the front of the steering wheel.These usually just snap on or off. Remoce the steering wheel using a small puller once you have removed the nut. . Usually available for aroung $10. Now that the signal mechanism is exposed you can wemove the plastic horn ring and also the 3 screws securing the mechanism to the steering column. Leave the mechanism on the colum for now. You can however reomove the screw that holds the lights, wiper and turn signal arm and let it hang free as there is no need to replace it if everything is working. Next you have to remove the two panesl under the dash immediately under the steering column. Tracing the wiring from the turn signal to where it enters a wiring block. This block has all the wiring from the turn signal, lights , cruise control and turn signals all on different modules. You are only concerned with the module from your tirn signals. To remove this module you have to separate the block by using a small ratchet and a 7mm socket. once the the bolt holdingb the block has been completely loosened the inner block can be oulled away from the outer block. Now the module containg the turn signal harness can be removed from the inner blosk and now you are close to removing the harness but first there is a plastic sleeve that protest the wiring as it passes along the lower part of the colimn. Squeezing one end of the sleeve you can push it out until it clears the colum. it can now be opened and reomoved from the harness. Now you can reomve the mechanism from the column and ease the harness up throught the steering solumn being careful to guide it through. The last two wires on the module , a beize and green wire that ties internally to the column will need to be cut and spliced into the new harness. Using the reverse proceedure you can install the new turn signal. First time may take a hour or so . One gets better with practice. Good luck John
