1999-2007 GMC Sierra/Chevy Silverado Tail Light Replacement/Installation Video

[@dr.a006]

Everyone do yourselves a favor and lower the spare tire out of the way first. Much easier access to that one clip above the tire. Also my plug terminal thing was mounted vertically and you can see which plugs go to which wires with the tire down and easier to clip wires back into place.👍

[@TonyTheTruckGuy]

One word of caution about that is that most spare tire cables on these 20+ year old trucks are rusty and won’t want to lower or raise back up haha

[@dr.a006]

Dos the new harness cone with the new lights or do I have to order that separately, if so what’s the part number for the new harness

[@TonyTheTruckGuy]

As stated in the beginning of the video, these specific lights came with the harness, but it probably depends what brand you buy or where you get them from.

[@qrsservices9576]

@@TonyTheTruckGuy Sounds good bro thank you do you have a link where I can order the lights that you bartered

[@TonyTheTruckGuy]

@@qrsservices9576 I got mine from Rock Auto, but I have an Amazon link in the video description for the same lights with harnesses and they are cheaper there.

[@gpt5002]

How the ffffffffkkkk did you get all the lights to light up at the same time??? Scanner?

[@TonyTheTruckGuy]

No I literally installed the lights and harnesses as shown in the video and it all worked lol. Did you get new harnesses?

[@derellcaldwell8653]

Help! I did the exact same thing on my 04 sierra but the break lights don’t work on either side… I went to “Pull a Part” and got the harnesses and I’m not sure if there the people because they’re used or should I replace the circuit board or what…? I paid $160 for the lights

[@TonyTheTruckGuy]

Make sure the ignition is on when you're checking the brake lights and make sure the bulbs aren't burned out and that you don't have the brake and tail lights mixed up. I'm guessing one of them problems is the issue, because I think these tail lights would work even without the harness update, the blinkers just wouldn't work right.

Could you reply back the part number and brand from Rock Auto? I need to order a left one for my 03 Silverado to pass inspection

[@TonyTheTruckGuy]

I think the link I have for the set in video description was actually cheaper than from Rock Auto, but otherwise if you’re dead set on ordering from rock auto, just look up the tail lights for like a 2005 Chevy 1500 and these should pop up.

Will the tail lights from a gm work in a Chevy. it looks like you have gm light in your bed and putting Chevy light in place of them.

[@TonyTheTruckGuy]

Yeah, I put the Chevy lights on my Sierra. The only issue I had was the little plastic pecker on the tail light that goes into the alignment hole on the body was a bit snug. A simple fist palm did the trick though hah.

[@alexfreeman3281]

do u need a new wiring harness every time u change tail lights?

[@TonyTheTruckGuy]

Only if you’re changing the style of tail light like I was

[@Cream_CurdlR]

@@TonyTheTruckGuy great video Tony. so if i didn't change the style and just went with stock assembly i could just unplug and plug in and thats it?..

[@TonyTheTruckGuy]

@@Cream_CurdlR Yeah if you’re replacing with the exact style light housing you’ll just twist all your old bulbs out and transfer over to new tail light housing. No messing around with routing a harness.

Never a bad idea when dealing with electronics, but not necessary in the case. Especially if you have the lights turned off.

[@ted2035]

Would this fit on my 01 1500 silverado?

[@TonyTheTruckGuy]

I don’t see why not, my Sierra here was an ‘01 and another guy at my work did this on his ‘00 Chevy.

[@TheLalo2208]

Do you know the wire harness part number by any chance ?

[@TonyTheTruckGuy]

Unfortunately no since they came with the lights in my case but you may be able to find them on gold or rock auto

[@Annunaki2012return]

My wiring underneath my bed is a mess. I’ve had other people hook up trailer lights as well was trailer lights in the bed for my gooseneck. The little post with the four plugs has nothing plugged in it and all lights work. I thinking about cutting the wire harness on the new taillights and just splicing the wires? Is this a good idea

[@TonyTheTruckGuy]

Sounds like someone bypassed that light module at some point, so yes this is probably the easiest way.

[@bullfrog7989]

Did these tail lights last?? Do they still have that shine to em or did they fade out?

[@TonyTheTruckGuy]

All plastic will eventually fade in the sun but these still look pretty good and the truck is not garaged. It sees 100°+ all the way to snow and -30° in the winter

[@bullfrog7989]

@@TonyTheTruckGuy awesome! thanks for that input!

[@dominiquenewman]

Will this work vice versa? (i.e. Sierra tail lights on a Silverado)

[@TonyTheTruckGuy]

Most likely, so long as you swap the harnesses too.

[@dominiquenewman]

Tony The Truck Guy Thanks man, I'll try it! You don't see too many swapping Sierra tail lights to the Silverado, so I was curious 👍

[@stoner63g11]

Can you use the stock bulbs and harness? When putting a 2003 housing in a 2000 Silverado

[@TonyTheTruckGuy]

You might be able to use the same bulbs, but you’ll need he new harnesses if you want them to function properly.

[@ryanmozisek6464]

Will a flat head screw driver work to pry open the clips that hold the wiring harness?

Yeah, that shouldn’t be an issue. I just used the pick because it had a bend to it.

Tony The Truck Guy Did they fit snug?

[@TonyTheTruckGuy]

Mine were basically a perfect fit. Only issue I had at all was the plastic alignment pin on the tail lights were a bit tight for the hole they go into, so it took a little persuasion with my palm to push them in but that’s it.

These are not the same for the 2007 gmc newer body style, maybe the classic style not sure. The 07 Sierra brake light and turn signal are wired together for power. This means when you hit the brakes both turn and brake light light up. There's also 4 light bulbs in the 07 Sierra

Yes this only works on 99-07 classic

[@stevenb320]

@@TonyTheTruckGuy classic style and regular style are not the same, different wiring configuration for the tail lights. The early 07 gmc would work but the newer style 07 does not. 99-07 had 3 light bulbs 07-13 had 4 light bulbs and the turn signal and brake light shared power. 07-13 was also a larger tail light assembly compared to the 99-Early 07 model. The other difference is the rear control box configuration for powering the wiring harnesses. Yes they look similar but they are not the same configuration for the wiring. Take a Classic style and Regular style wire harness from 99 and try it with 07. 07 has more wires as well as more pins in the plug.
