Still fucked.
Tonight I went to turn my parkers on, the fuse blew straight away.
Get back and disconnect the headunits wiring from the back of it. Put new fuse in, switch on parkers... they work fine. Plug radio back in, fuse blows.
There are three wires I'm still suss on. A red with green stripe, this one is what I think is constant power (pretty sure thats right). Red with black stripe, I thought it was ground... but I don't think so. There is also a blue wire, which I had wired to acc to switch the hu on.
Anyway, i'm fucking pissed off as I can't get it to work at all now...
Radio was working perfectly fine until I switched the parkers on and the fuse blew... was still working then, but once I took it out and disconnected the wiring and started to muck around, it was all over.
GRRRRRRRRRR
