Now then, does anyone think that BMS are blowing smoke up my ass when they tell me that I "MUST" buy the other steering wheel controls to go with their harness kit ?
They don't sell this but they tell me I need to have 61319123287 which is $200. That's $200 in addition to the $99 they want for their harness kit.
So my question is, does anyone think that this DIY (link above) replaces the need for both the new steering wheel controls AND the harness kit or are BMS accurate when they tell me that I must buy the new controls.
Anyone know ?
