hooking up a head unit to a evo 4

[Dnos]

hi, well i had installed this head unit my self last year and had it perfect.

I installed a sub and amp the other day, it kept turning of when moving goes when stoped. so i thought lose connection somewhere.

Remove the head deck and my wires that i had connected to head deck came lose. Now i try to hook it back up and i can only get i to work when the igintion is on cannot find the wire to keep it going when its off.

I cant find a wiring guide on the net even after a good hour searching.

I've found the fat blue wire gives the power i want (turns of when key is out but immlumtion goes out when ignition is off so thats useless)

please help with this, just need to know what all the wires do. My head unit colors dont match with the car and there no diagram on the unit either

check all fuses mate and also the earthing points, if all are good and hooked up right it could be be cream crackered, try another head unit just to see if that works in there

just got it all working unit sup and amp. Hooked them all up to the fat blue wire.

but now when i put unit in the tape must of came of the wires (doing budget way) and i have triped a fuse, i have no centrel locking or speedo. What fuse would connect all of that? its happened before when i bought the car but i wasnt present when the car went to get fixed (fuse and other things)

I've checked the fuses but they dont look burnt out, just like last time

I'll have to pass on the particular fuse, there are 2 fuse boxes one under the bonnet and the other is to the right of the steering wheel behind the pocket that pulls out, jus have a look at em all buddy
