Currently have a fass 95 hpfp on my truck. Just bought a very slightly used fass heavy duty 150 unit. My question is, does anybody know if it is plug and play with the electrical wiring? Meaning- can I use the existing hpfp wiring for the fass 150? Unplug hpfp and plug in fass 150? Electrical plug appears to be the same

 

If both units are for the same year truck, the wiring should all be plug and play as long as they are both frame rail mounted units, and both fass pumps

 

Ok both frame mounted . Both have same electrical plug/ connector- so I am good!
