Ppv leftovers... From police buildout?

[daniellsonn]

This equipment was left in car with wires cut.
What do they do?
And damn, the connection for 2nd battery is nuts too . Can anyone tell me what they were for?

If you haven’t seen this yet, it’s a gold mine.

That's actually the connection on your primary battery, the secondary is behind the headlight.
My impression is it's for radio equipment. Some of those wires should power a fuse panel behind your glove box and one by your jack and tools.

I wonder what the "AMP MASTER" does...

Also not sure what the AMP MASTER box does. Maybe it's the siren? What wires are going to it? Can you open the box?

Amp Master might be a power distribution box. I went to the B&B website, but didn't see it in their product catalog.

See if I can get up there

Hi y'all, still cannot find horn under my 2012 ppv.
Found alot of other p add ons.
Would Kerr remove horn during upfit?
And would anyone be interested in the
Previous mentioned upfit items.
Thanks. Daniel

 

[mikez71]

I maybe interested in electrical stuff.

Are you trying to remove all the PPV specific wiring?

Horn info is here. Read through it. It shows you where the harness is for it.

Opened amp master, has another fuse box .
It's a power inverter to power lap top and accessories. A lot of wire goes into metal cooling thingy? Took me a minute.
But..... Gotter Done

 

[daniellsonn]

Iam now wondering how much 110 it puts out?

 

[mikez71]

That thing with cooling fins is your ECM.

May not put out 110V, laptop power is often a DC to DC converter.

I wonder what the dip switches do.

No not really, it's running good, may take apart
The amp master, see how much power it delivers. Talked to Florence st company that bought them out, she looked and never got back
Said they were ancient.

 

[daniellsonn]

Ok, sorry it took so long life got in the way.
However the box it puts out 48 volts.,. Im thinking lights, siren . It's has a tiny battery up front running the truck.
Thanxz to all.

I have a feeling it's for radio.
