You could plumb the MAP sensor via a vacuum line if needed. It may not be 100% as good as being in the IM, but it worked on many cars for years being mounted to a bracket on the engine or firewall. There might be a few milliseconds delay in the signal is all.

thats actually how mine is connected. the map sensor is only 3" away from the manifold but i used a 3/8 NPT to 1/2 vacuum line and just connected it that way. and the wires i tapped into the main harness that runs right beside.

i wish i had more time to play with it bing my DD but i have to get my other projects done aswell.

update


11000 km no issues with the swap.

i still have a few codes but i wont be able to get rid of them with out some work. ( been to busing working on my other project car)
since i have the rt computer its looking for the intake solinoid which sets a code. the other do i have is to deal with the evap surge solinoid mounted on the 03+ which i dont have.

and other then that i had a code set from me bumpign the cruise control switch on my steering wheel and i havent gotten around to hooking up cruise control

i think this is one of the best engine swaps you can do on a budget.

I always have the MTV relay circuit code from running an R/T pcm in a non R/T car. It has become like the P1684 equivalent. Then there is the P1686, since it wants to find the SKIM module that isn't there. But neither code sets the CEL, so it isn't something that bugs me. :D

The only way to be rid of the MTV circuit code, would be to get a wire connector inserted onto the correct PCM connector pin, and wire it to a relay coil, and ground the other end. It need not be a functioning relay, just the coil, or a resistor that is close to the same value of the relay coils for your horn/starter/fuel pump.

Thumpr no need to change the harness, or move the cam sensor all you have to do is maybe legthen the pigtail wires maybe i qaute I know this first hand because i took a srt motor out of a pt and put a soch motor in it and took the srt4 moter and used the block and a diff head and all works fine , If anything you may need to just take some of the factory tape off of the wires to gain lenght

considering i already did the swap i had to legthen the wires about 4 inch in order for them not to be tight as i was affriad they might of ripped out

great post and good to hear for my 05. Any idea if my 5 spd trans bolt up to a 03 + PT 2.4 or would I be better getting one w/ a 5 spd and swapping motor and trans?

Small post resurrection but I had a question about this code. Will that code affect emissions if they do the plug in test? Or since it does not activate the CEL it won't show up when they do the test?

I'm sure they could see the code, but it does not illuminate the CEL, and doesn't affect emissions. But who knows.... I guess it depends on the inspector.

The PS switch does light the CEL, and also does not affect emissions, but they will fail you for that.

Oh ok just making sure I've got my bases all covered when doing the swap. Don't need to be failed for emissions for that code. I know if you had a CEL when you came in they would fail you.
