RealTruck AMP Research PowerStep Plug-N-Play Harness | Fits Universal (Except RAM & Toyota) | 76404-01A |

I installed my AMP research steps on a 2015 GMC Denali 6.6. I got them installed just under two hours. There is plenty of room for the cords to be fused.

Works just like they say it does. Plug the middle one in the OBD2 port, plug one end into the PowerStep harness and one end stays open for service or for other OBD2 accessories such as the Banks iDash or Edge CT/CTS2 digital gauges. The caveat on the install for my 2016 Ram 2500: the instructions show unscrewing the factory OBD2 port and plugging in the end port of the harness into the factory bracket. Doesn't work on the Rams that way. Their port snaps in place so I've had to zip tie everything instead. I'll probably fabricate a bracket to mount the open OBD2 port so a service tech doesn't have to unplug my steps every time a go in for maintenance.

I gave 5 stars overall because the harness itself once you get it installed is an awesome setup. Most know all OBD2 connectors and ports are universal, but be aware that unless you drive a GMC or a Chevy you will have to modify placement of additional (new) OBD2 connector from this harness. The connectors on this harness are universal only with the port connection not with the bracket that the connector will be mounted on. Brackets are manufacturer specific and in the case of this harness it is only compatible, without modification, on GMC and Chevy.

I installed this on a 2014 Ford F-150 Lariat 4x4 with 5.0 V8 and 5.5' bed. It was easy to install, by moving the existing OBDII port and rebolting the new one in its place. The Amp Research plug then is a direct plug and play into the extra OBDII port. No cutting or splicing is required. I can only give this four stars however since it is about 4x the price that it should be listed at. Nevertheless it works, and made the job much simpler. Therefore, if you don't mind paying for it, it's a great product.

Product worked great. Had to use on my 2015 Ram 2500. Installed Amp steps and then later on added a Bully Dog Tuner. Needed a way to split the odb2 reader to run both.

This is a great addition to the AMP Research PowerStep product, albeit pricier than running an OBD II splitter. NOTE: If you own a RAM truck, this does not directly fit into the OBD II slot that is molded into the kick panel under the steering wheel. I attached mine with two small zip ties and it does the job, just not OEM fit like the original port.

I was being cheap. I admit it. I got a cheap splitter when I installed my Power Steps. After a while, the steps would deploy/ retract when I started the truck. After some troubleshooting I found it was the splitter. Bought this one and problem solved! Buy once, cry once.

In the question and answer section of this listing Bryan A Jordan on July 27, 2018 stated that this product will work in a 2003 gmc/chev, ***** WRONG ***** , when speaking with the tech dept at amp, they (Chris) told us that the pig tail would not work for late model gmc/chev (2013 and older). I purchased product based on the statement made in the listing . the downside, waited to long to return, my loss

Speedy delivery and as advertised! Exactly what I wanted!

exactly what I need for my AMP steps

Nice addition.
