Hey guys! I decided I would take the time to go step by step on the installation of AMP Research's Power Steps and their Bed Step. I also didn't want to pay to get it installed lol. Everyone wanted to charge way too much...
The directions say skill level of 4 which is their highest rating on their instruction manual, but I tackled this installation with no problem at all. I think I read on another thread install review that the newer Tundra's have different colored wiring, so take note that this installation is on my 2008 Tundra Crewmax. (Wiring may be different on other years)
Here we go.
First we'll start with the easy step. The AMP Research Bed Step.
This was kind of a piece of cake. The install is very easy and basic, but its hard to get to the bolts to tighten them once you put the support arm on.
Here's what we are working with. This AMP Research Bed Step is specifically for the driver side of the bumper.
The components of the box. From left to right: Support Arm, Moving Arm, Step, Instruction Manual and Warranty info, and Hardware.
First thing you want to do is grab the support arm and the moving arm,
and then bolt these together with the correct hardware like so.
Once these are bolted together, slide underneath the truck (It really came in handy that I could sit under my truck cause of the lift.) Find these 2 bolts to mount the support arm to.
Mounting this support arm to these bolts is the only tricky part of the installation. I forgot to take a pic while i was doing this... I was getting frustrated cause there is no room to work under there. Just make sure you have a decent length extender when you tighten these bolts down.
Now that the support arm is bolted to the truck, you should have this.
All that is left to do is mount the step. You can adjust the step left or right to your liking so its easier for you to grab the step with your foot to deploy.
You need to slide these into the step so you can bolt the step onto the moving arm.
After you find where you want your step to sit, bolt it in and you're done!
The finished result!
Here's a quick video!
Now onto the PowerSteps! These aren't necessarily harder to install, its just more time consuming. Now lets start!
I didnt bother taking pictures of all the parts cause this box had a lot more then the BedStep.
The first thing you need to do is find the Emergency Brake Cable which is on the driver side. Follow it all the way to the end of the rear driver door till you find this bracket holding the brake cable.
You are going to need to unbolt this bracket, separate it from the cable, and then reattach and bolt it back on after turning it 180 degrees.
Now find the Motor and Motor Linkage and bolt it together. Each motor and Linkage part is not side specific so don't worry about that.
Starting with the drivers side, find the second set of factory holes from the front to mount steps on. This is where you will mount the first motor assembly.
These were on pretty tight... so be careful of the pinch weld cause it got me pretty good haha
Once you get the bolts out, bolt the motor and assembly on.
(I forgot to take a picture of the motor assembly after it was mounted)
Now lets move onto the rear Idler Linkage Arm. This will go on the last set of factory step holes.
*Repeat these steps for the passenger side minus the brake cable part.
Now that you have all 4 mounts bolted onto the truck, we can now bolt on the steps. The steps can be easily adjusted before or after the complete install. Specifically for the Crewmax, you need to line up the back of the step with the edge of the rear passenger door.
Like I said, if its not perfectly lined up, you can adjust it after your done with everything. Its hard to tell when they are down and you cant move them due to the motor. I adjusted mine perfectly after everything was wired up since the step was now able to hug the body and I could see how off I was from the edge of the rear door.
Well once you get a good enough alignment, bolt the steps to the mounts.
*Repeat steps for passenger side step.
Now comes the part where some people may want a shop to do the install or why they took it to the shop to get installed. Wiring! (It really is easy, AMP Research made it as easy as it could get.)
You have your control box, your fully wired wiring harness, Posi Taps (Which I now love!), and the LED light kit is now integrated with the wiring harness!
Anyways, find your control box and 2 11'' zip ties from your packaging and mount it to the wiring loom closes to the fire wall.
Find your positive wire with fuse, take the fuse out (make sure you put it in a safe place), and then bolt it to your positive side of the battery.
Now find the ground cable and bolt it to the grounded bolt on the fender.
Now once you have done that, find the longest leg of wires and run it along the fire wall to the passenger side exiting through the fender well outside of the frame.
Now once its out in the fender well, find the path over the frame between the body to pass the wires through like so.
Next, open up the door and remove the kick panel along with the sill plates. Now pull up the carpet to find the grommet which is towards the center of the foot well. Cut a slit in the grommet enough to pass through the blue and white wires from the passenger side wiring.
Now find the black plug in the kick panel area.
Connect your blue wire from the AMP harness to the blue wire in pin 1 using the supplied Pois-tap.
Now find the white wire in pin 9 and connect that to your white wire from the AMP harness.
Now that the passenger side is all wired up, we can now connect the harness to the passenger side motor like so.
The next step after you connect this is to slide the motor cover on, this was only tricky cause its a tight squeeze in there to snap these clips in. I didnt get a chance to take a pic.
Now that we have wired up the passenger side, its time to wire up the driver side. So go back to the beginning of the harness and find your short leg of wires. Now do the same with this side and send these through the driver side fender well opening.
Remove kick panel, sill plates and lower dash piece from driver side.
Pull up the carpet and find the grommet towards the center to feed the dark grey wire and blue wire through.
Find the black pin connector in the kick panel area, find pin 15 and connect your blue wire from the driver side harness to the blue wire in pin 15 with your posi-tap.
Now go to the main electrical area under the driver side dash and find the big pin connector on the top left. Your going to be looking for a dark grey wire in pin 2 in the green row.
Now lets put the motor cover on, open both driver and passenger side doors, find your fuse that I told you to put in a safe place and plug it in. Now put your battery back on and cross your fingers! lol Once you put your battery on you will here the step motors moving the steps into open position. Congrats! You have just installed your AMP Research power steps!
Now we can go back and reinstall the kick panels and door sill plates. Zip tie all loose wires, align the steps now they go up when we close the doors, and wire the led lights now that the steps go all the way down. I did not wire mine yet since I dont have a good enough drill to get through that pinch weld. But I will post back once I do install them.
For now, here is a quick video of the newly installed AMP Research PowerSteps!
For those that dont know or didnt know, you can place your foot down on the step with pressure as you close the door to keep them deployed if you need to use the step to clean the top of your truck or get something like I show you in the video.
