2019 ford FPIU

[tscroggins]

Apologies in advance if this is a long winded post but I’m looking to get clarification on some things as I’m not a professional upfitter. I have a 2019 Ford Police Interceptor Utility and I installed a XPR5550, however it’s not hooked up to power yet. I plan on installing a APX8500 at a later date. The vehicle has a 6 way power feed harness with 3 hot wires rated for 34 amps each and 3 ground wires.
What I would like to know is, can I wire both radios to 1 hot wire or should I dedicate 1 hot wire per radio? According to the APX cut sheet, the transmit current @ 100 watts is 30 amps and the receive current is 3.2 amps. For the XPR the transmit current is 40 watts @ 14.5 amps and receive at 2 amps. Just want to make sure I do it right cause I’d rather my car not burn to the ground lol.

I'd probably have one radio on Hot 1 and the other radio on Hot 2. While unlikely, if they are transmitting at the same time, they will draw more amperage than Hot X is rated.

Thanks, That’s what I was thinking too

I am curious what gauge wires they FORD, used for power and ground. Do the grounds terminate in the cabin close to the harness or do they come through the firewall?

Here how I use the factory upfitter plugs for the explorer. I tie all the constant postives on the 6 pin into a blue sea fuse panel. The one i use has a negative side also so I will connect those over there. This panel has hot all the time. Then from there I connect radios and other console devices etc. Usually I install a siren with just the head in console and brick in the trunk so it will have its own heavy power wire etc.

On the other harness is a lower current switched power which I sometimes use to tie into a charge guard to switch on /off.

I believe the 6 way upfitter plug is 10 gauge wire

So just to clarify, you tied all 3 hot wires to the positive lug and the 3 ground wires to the negative lug on the blue seas system fuse panel?
