Default injector swap question

i am having a buddy do a 99+ intake mani swap on my 95. i have a 99 intake mani, fuel rail and injectors, and power steering bracket. so this is a complete bolt up i know that, but do the injectors meet my plugs on my harness correctly? or do i have to splice them in?

the fuel pressure is different. the 99+ injectors need 49psi, your 95 only puts out 39psi. You will also need to use the fuel rail from the 95 as the 99 fuel system is return less and not compatible with your jeep

my 96 (before the 97 facelift) has the return less fuel system with 49psi on the rail...didn't know 95's were different!?!?....what injectors are you using?....while at it, you should swap them out for the ford or dodge/chrysler four port injectors, they are plug and play, just make sure to use new o-rings and dab them with a little oil so they don't rip.
