i saw that link and I think its nicely done. But I don't know weather its 12V Acc or 12V remote is constant power... please help.

The constant power from the battery is actually (A4- +B). Atleast thats the one I used when I did mine.

just to clarify its A4 and B+ together right?

Ali SC4

Yes A4 is the pin number. B+ stands for positive power from the battery.

I happened to have the OE diagram and the plug letters are different from the ones on that website... just had to double check before I short anything else....

Ali SC4

I used the info on the site for my whole install and it all worked perfectly the first time I turned it on. If you have conflicting info on the OE diagram I would probably just use a tester on all the wires while the car is off to see which pin the constant power is.

i have everything else worked out except for the power thing. The conflict was a ground cable and +B cable were in same spot if you look at the OE and the link. didn't want to short the radio thanx
