i hope those who have fitted aftermarket h/units with the steering wheel control adapter can help me out on this.
i've bought a new headunit the other day and from the same shop i got the steering wheel adapter kit - specific for the a jvc unit so i thought it should be a simple case of plug and play and i'd be away.
let me explain in full so that i give as clear a picture as possible:
i bought the single DIN fascia adapter from VX which came with the wiring (n.b. if anyone needs to purchase a signle DIN adapter i would highly recommend going straight to VX, £25 for the fascia plate and wiring harness! the shop i bought the stuff from wanted 30 quid for a black or silver fascia plate alone!!!)
anyway, the wiring harness from VX plugs directly into the wiring coming out the dash, this gives you your speaker and power leads and also a red adapter for what i presume is the steering wheel controls.
the black and brown connectors are then plugged in the corresponding connectors for the steering wheel control harness and then finally the actual headunit connectors get plugged into those - ALOT of wiring!!
now i've plugged everything in that needs to be plugged in but the steering wheel controls don't work.
do i need to earth the black box for the steering wheel control harness, there is a loose wire on it which i can only presume needs to be earthed, but its purple!! i've tried earthing it with no luck!
i should add that this black box converts the wiring that intercepts the power wires into a 3.5mm jack that plugs into the headunit.
the red connector block which is part of the vx wiring harness isn't connected into anything, do i need to do something with that? there is no way that the steering wheel controller harness can plug into this red block as the red block is much larger.
JEEEZ....this is turning into an essay!!!
i'll post some pics if it helps, but i'm hoping someone can tell me that i've missed something very simple and then i'll feel silly but at least it'll be easy to sort it out.
