Fuse issue

[sprinter1221]

Hey I've been having a issue with getting my headunit to work in my vx. Everything is connected as should it will turn on with ignition on but once I run the car it turns off and doesn't come back on..
I don't a circuit test on all fuses with car ignition on with car running etc..
With car running there's no power to the instrument fuse
Front and rear wiper
Cigarette lighter
And the 7.5amp fuse
I have replaced those fuses and still no power to them would anyone know the issue?
It's a 2001 vx commo
It had a amp installed in the boot but looks like old owners didn't get it going as there was no tape covering any of the exposed wires so I removed it all back to factory.

unless you are good with electrical

Possibly the head unit is cactus from bodgie wiring?

Have any power at the head unit (radio), when ignition on?

Yes then loses it when turning car engine on... can connect Bluetooth and listen to music but once engine runs then doesn't turn on

i would think head unit has been damaged from wiring through wrong circuits
was this a working head unit prior to install

Yes it was in my vs and used the same method with using connectors for the harness and worked great first go...
When putting the headunit in the vx I did have it working with engine running but kept cutting in and out then it blew the radio fuse and hasn't worked with engine on since
