Tried to install the PopNLock power tailgate lock on the 09 Sierra. Having trouble with the wiring. Instructions say to wire to the tan and grey wires found in dash fuse panel. There are several grey and tan wires present. Their technical assistance was zero help. After browsing the internet I even tried to remove driver door panel and attach to one of the four wires going to door latch motor. Again no luck. The actuator does work if you run across battery. Could it be a problem with relays? Any advice as to wiring diagram would greatly be appreciated. If it works it is suppose to lock/unlock the tailgate lock with key fob.

Go into the window swtich and yes it will work with the key fob ive done a few before..

 

i forget how it goes but i think the reg/ext cabs the wires are right behind the seat under the sill plate and the crews you have to go into the door.

If you already went into the door panel, then simply find the wire that is activated when the you lock/unlock your door lock. You can do this with a volt meter. Once you find it, go ahead and tap into a 12 volt source at the fuse box, and using a relay, send the power to the door actuator. You can keep the relay and wiring in the drivers side door (or passengers if you prefer), and simply send the wire with power back to the rail gate actuator. Key is to find the wire in the door that is momentarily powered when you lock/unlock. Good luck. Al

Appreciate the replies. Kit comes with wiring harness and relays. Instructions say to tap into grey and tan wires, however could'nt get the actuator to work. Called popnlock co and they said it 'has never happened' but that they would send a replacement harness with relays incase the relays are bad. Very frustrating...I have installed power running boards, off road lights, dvd players, stereos in my vehicles for years. Everything has been plug and play. Their tech support says their instructions are from an installation in an 07 and that maybe there was a change in wiring for 09. Guess I'll have to buy a manual with wiring diagram. Was hoping someone on this forum had either installed on of these PopNLock kits and/or had some insight into 09 crew truck wiring diagram for the door lock/unlock.

      The no sound problem is the audio amplifier. The audio amp has a heatsoak issue in some circuitry which causes it to miss the wakeup handhake. If it doesn't respond within a certain time parameter, then you get no sound. I brought it in and had the software update, but after further testing the tech made the call for a new audio amplifer. The software update I belive gives more time for the amp to respond, but if the amp is defective then you can still get no audio at times. After the update it went 12 days before no sound. After doing some research, apparently the fix is a new (updated) audio amplifer, the circuitry internally has been improved to better deal with heat. I had to wait 2 1/2 weeks because at the time, it was on backorder with no eta. Well the amp came in earlier this week. I had the amp and programming work done today. After picking it up I stopped at a few places, and whenever I started my truck, the audio was on instantly, so whatever they did it appears to work because it's never had sound that quickly......Hope this helps

      Make sure the latch mechanism is properly greased. Look at the catch for fresh marks/scratches. And see if it has moved a little, too.

      Thoughts on these wheels?

      By PBNB · Posted

      I have the 18" black mutilspoke wheels that came with my truck. I like them as they are very subdued and look good with the 295/70's    I am sure that the next set of wheels I get will be some after market all black wheels. Or maybe some AT4X wheels.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Interesting question which you partly answered in the word 'potentially'. I think that is going to be a 'point of reference' inquiry. What are the touchstones?    This will sound petty but it is the main source of end fighting in threads on this topic. Define a motors "Life". Think about the various arguments that have been entertained on these pages in that very argument.    I can only speak from my viewpoint. Engine "Life" in my world is defined by power cylinder integrity. For the majority of engines it is the bore/ring interface that quits first. Loss of seal. Oil consumption and loss of power. Most Pro motor builders would agree and there is a good deal of information on using "Leak Down" as a primary indicator of bore integrity. At home a compression test is more the thing. If we can agree on that then I think CC Jensen has done its homework and I'd find it valid.    Now by my own definition, Dizzy, wife's Ecotec 2.4 I-4 has been dead since about 80K miles. And yet we have logged over 200K miles more on it. "Life" and "Usefulness" are therefore independent.      I know a mature fella right now who has just hit 300K on a Mitsubishi 3A92 NA MPFI motor and has done compression test every 100K. It was 205 psi after break in and is now about 195 and still even. He uses shelf oil but good filters and adheres to a 3K mile OCI. He even do UOA's on each of them for the first 50K.      I also know a fleet mechanic with that same motor that gets 300 to 500 K out of them but the are oil using, wristpin sloppy, skirt slapping motors. He ran one with a piston pin so loose the piston was bouncing off the cylinder head for about 20K miles before he called TOD. Both of them claim success.
