2010 3i: adding cruise ctrl
2010 Mazda 3i Sport:
Anyone made it work yet? Everyone says: "Just buy the brake switch and the steering-wheel switch plate and plug 'em in!" The backlights work, the brake switch works, but that's all. It's a 7-pin connector, 3 are unconnected. Is it missing wires, if so, where to? Is it missing SOFTWARE in the engine control unit?
With older 3i's, this idea worked fine. By 2007/8, you had to add a ground wire to make it work. So, now what?
If anyone has a schematic for the steering wheel/column I'd REALLY like to see it!
PS- Disclaimer: If you don't know the safety rules for airbags, don't even think of trying this!
