4th gen installation of RC AMP electric running board wiring issues

[Sidrta]

OK, so I just received my AMP Research powerstep from Real Truck to install on my 4th gen Sport. The installation took awhile and then when I got to the part in the manual to connect the OBD plug to the truck's wiring system there is nothing in the install manual that tells or shows you which wire to splice into. It says blue and white wires, but the problem is that there are 5 white wires and several blue ones. Called Real Truck and they were unsure but assumed which two. I tried their suggestion, but didn't work. Now I have to wait for their engineering folks to email be back some day. So, the frustrating part is my truck is all torn apart now and the assume wires appear not to work. Has anyone else done an install yet and has any information on the correct wiring..
Thanks

Post some pictures of what you are asking about. This may help identify what you need!

Here is a picture of the plug that needs to be tapped. One can see that there are several white wires. I was trying not to have to tap each wire separately to see if that was the correct one.

So, I was able to work out the wiring issue.

For anyone else doing the install I have attached a picture of the correct wiring. Also, be aware that the motors will run backward out of the box and you will need to reverse the two wires going into the plug to get the correct orientation. Hard to say if they will correct this issue.
I hope this helps others taking on this project.

Do you remember which wires from the OBD Plug connect to the Tacoma's factory plug?

I got the steps and they are Rev. 2 with the Smart Series Module (Bluetooth connection with APP control) I'm going through the instructions on page 9 and the wording on the steps have me confused.

The OBD Plug has 3 wires, White, Blue and Yellow. From what I understand, the Blue wire from the OBD plug taps onto the White wire on pin #20 and the White wire from the OBD plug taps onto the Blue wire on pin #9. Yellow wire connects to the Amp harness Yellow wire. Do I have it right?

Good evening,

Did your wiring bypass the use of the OBD port, or do you still have to use the provided ODB plug?

Thank you,

Steve

I still had to use the plug. I have seen where if one wanted you can purchase a Y so you can use the plug for the running boards and still have access for dialogistic. I hope this helps.

Working on this in the next couple of days. Did you have it right? . Thanks

I did, it was White wire with blue and Blue wire with White. I also ended up getting a plug connector from AliExpress to avoid poking any factory wires.

I just wanted to add my experience for anyone that searches or Google's for 4th gen info on the installation.

Toyota Tacoma 2024 - 2026 Part #76362-01A


Disconnect the battery before starting. I don't remember the instructions talking about that.

The wire colors are different on the actual motors compared to the instructions. I matched colors at first, i believe orange and white on the harness to orange and white on the motors. The motors ran in reverse, meaning when I opened the door, the steps went up. Simply switched wires and it ran correctly. I actually called tech support to ask about the wiring, and that the instructions talk about the possible need to cycle the motors to get into the correct position....apparently the new "smart" module will figure out where the motor is in the cycle when it feels resistance. I overthought the process. Just put it all together and swap the motor wires if it runs incorrectly.

If you measure the 20" and 57" (or whatever the instructions say) for the LEDS, look above the pinch weld where the light would mount. At those measurements there's a plastic plug that interferes with the mounting of the LED light. Need to move forward or back accordingly.

The very first step of the instructions is to install the motors on the linkages. I found myself taking them off of the linkage after the linkages were installed because the instructions say to manually cycle the steps after each torqued bolt. When the motor is installed, you can't manually cycle it.
Also, with the motor off, it would have been easier for me to mount the steps to the linkages because with the motor on, it puts the drive linkage at half cycle.

Great steps. Perfect to help my shorter wife and elderly mother get into the truck. Instructions could use some help though. Anyway, it's pretty straightforward, just time consuming.

Thank goodness for this thread! The version of the install instructions I’m using must be rev 1 as it DEFINITELY does not include the pinout for wires 9 and 20. Much appreciated!
