3.5 swap harness confusion

ive searched and read till my eyes were bloodshot. for the life of me i cannot put together exactly what is needed from what is not. the information in some threads are pretty much drowned out with what seems to be info that isnt necessarily needed for the swap. Eng 92 says there is about 11 connectors from the a33b harness thats needed to mate the a32 harness to the a33b ign, immobilizer, and cluster, thats pretty much understood. but how do i go about supplying power to the ecu and is there a way anyone can clarify what sensors need to be swap for the engine harness to be plug and play. on top of that. what wires need to be hardwired in and am i missing anything that may need to be repinned or hardwired that may throw a code or make this swap less "stock" than desired ie "working a/c no codes etc.

so you are doing a FULL 3.5 swap not a Hybrid 3.5 with 3.0 timing..

what you need is a plug and play 5.5gen ECU harness that will plug into the 4gen engine fusebox power/sensor distribution get routed thru the firewall into 5.5gen ECU, with additional wired in Immobilizer harness, Egas pedal, a33b cluster, and all 4gen body sensors and components like fuel pump.. you would also need to wire in a separate relay for the Egas TB and a second ECCS relay for the 5.5gen ECU.

Having done countless hydrid 3.0/3.5 swaps, an HR swap, and fixed tons of 5.5gen wiring ECU P0300 code issues it's definitely doable. BUT if you are not comfortable with wiring and tracing out/testing/probing pins components and continuity this is going to be an insane swap for you.

I wouldn't even look at 02-08 35DEs i'd go straight to the 09+ 3.5HR and 6spd.

Personally I have a 3.5/6spd in my 4gen. not a full 3.5swap - 3.0 timing hybrid. fast, torquey, 6spd on the highway is much better gearing
