Hey Ronald. So long as they're installed correctly the Roadmaster 7-Wire to 6-Wire Flexo-Coil Kit item # RM-146-7 and the Blue Ox 7-Wire to 6-Wire, Coiled Electrical Cord item # BX88206 will have the same locations and functions.

It looks like you're looking at flat tow setups for a 2022 Chevrolet Trailblazer. Here's the parts you'll need:

Tow Bar and Safety Chains - etrailer SD Non-Binding Tow Bar for Roadmaster Direct-Connect Base Plates item # e74ZR

Base Plate Kit - Roadmaster Direct-Connect Base Plate Kit - Removable Arms item # RM35FR if you have the L, LS, LT, or ACTIV models or item # RM46VR if you have the RS model

Wiring Harness - Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit item # RM26FR if you have the L, LS, or LT models or item # RM38FR if you have the ACTIV or RS models

Battery Disconnect Switch - Roadmaster Automatic Battery Disconnect with Switch item # RM-766

Supplemental Braking System - SMI Stay-IN-Play DUO Supplemental Braking System item # SM99251 or item # SM99243 if your motorhome has air brakes

High Low Adapter - The tow bar needs to be within 3" of level. If you measure the height of the inside top of the hitch receiver tube on your RV, and the height difference is more than 3 inches above/below the base plate tab height, you'll need a high/low adapter. I have linked a FAQ article that explains all this in more detail along with our selection of adapters.

What kind of motorhome do you have? You can add this information and any other questions you have where it says Reply to Jerred H and I'll be happy to answer them.

Hey Ronald, did the wiring between the Roadmaster and Blue Ox cords line up the way you expected? Knowing how the pin locations matched could really help others setting up their flat tow wiring.
