hello, ive just fitted a double din head unit, and it wasnt working so well so i took it out, and when i put the old (pioneer) head unit back in, it doesnt seem to work, you've got yourlive and your acc, now the problem i have is that im not getting a power thru from the acc when i turn the key to the on position, but im getting power thru fine on the live!!

can anyone shed some light on this please? ive looked for an acc fuse, but the only one i can see is the stereo, and that ones fine!

It could be your ignition switch

Otherwise check the fuse for the cigarette lighter. It's on the same circuit

my cigarette ligher, 1 still works, and 2 works even without the key in! its hard wired to the battery i would assume!

Does you heated rear window work?

how do i check?

Does it light up yellow with ignition on and it pressed it.

yes it does! i was thinking maybe a broken wire in the loom?

Hard to say

Really, you need to test the red brown wire coming off the ignition switch when the ignition is on and see if there is 12V

yeah il do it over the weekend, if thats fine, is there anyway i could wire a wire from the power to the heater controls, to the acc on my iso cable?

You could but ultimately that isn't the fix. You should really work out why it's happening and fix the root cause.

noo, just as a temp option till ive got more time to look into it further!

Yeah as a temp just find an ignition live and use that instead.
