Harness for AMP Powersteps on Power Running Board Equipped Truck

[youn1033]

I had some Tri-Mode Steps on my 2018 Sierra Denali Ultimate, however I removed and sold them due to not liking the Chrome or how far they hung down..

 

I was under the impression I could get some AMP Powersteps that were plug n' play and I could just plug them into the existing wiring harness under the truck were the old ones connected in? Is that not the case? It seems like it would be quite easy to mount them and utilize the existing harness since it already correctly handles when to drop/raise the boards, etc. Is this possible?

No they don't interface with the OEM harness.  The AMPs should have come with their own Plug-n-Play harness.  You need to connect part of it to power/ground from the battery and the other part plugs directly into your OBDII port under the steering column.
