Can I cut/remove extra wires from the THAR-ONE-MAZ3 T Harness 20 Pin Connector

0 votes
I just finished an EVO-ONE install on my wife's 2016.5 Mazda CX-9 using the THAR-ONE-MAZ3 T Harness which greatly simplified things. While it seems ovbious I'm still going to ask...for the 20 PIN Connector, the T Harness only uses 5 of them(6 if you include the hood pin), but then you've got 15 (14 if the hood pin is wired) colored wires hanging off it doing nothing/going no where. What other applications specifically for this vehicle would they support ? I'd like to remove them from the connector. As of right now I put electrical tape on the ends of everyone of these wires just to ensure there is no contact under the dash.

My assumption is I can remove these without issue, but if they have some potential purpose I'd keep things as is. Thanks.

If everything works fine then you can remove the uneeded wires to make the install look cleaner thats what i did on my 2014 mazda 3
