The connectors from AliExpress are identical to those already on the car. The point behind them is to make an adapter cable that crosses the wires needed from there current location to the new location and to make it ready to add in the extra wires. I suppose you could do without them altogether if you wanted, but the reason I suggested, and why I'm also using them, is I feel it makes my life a bit easier.So basically I install the icam module and then coding (I'll figure it out). From the icam module do I need to add wires from the R3 transistor to the BCD?
After that, I need to rewire my headlights connector (the female-male plugs from aliexpress arrived), but apparently my car is already with the new connector, so i'm thinking maybe i'll use them to test the headlights.
