Heated seat w/ aftermarket radio

[Pharix]

I sent a pm to Mpgrimm2, buuuut then I got pointed here.

The harness you guys make, does it work without the 8.4 radio? I just wanna use the switches on the dash since I have an aftermarket head unit in.

I have a '17 ST but I don't have the grey connector in the floor.

You need the 8.4 HVAC control system... Replied to your private message
