18 Denali power running boards

[Mitchell Z]

Does anyone know if an 18 Denali with out power running boards would be pre wired for GM ones? Obviously I know amp ones would be the obvious choice, but i have a line some some oem ones off a totaled 18.

Welcome to the forum.

You will need to look under the rockers to see if you have a harness connection for running boards. You will also want to see if you can grab the switch for turning the running boards on/off.
