and you will either have to swap over your coil packs, or you can rewire your harness to use Coil-on-plugs.
So the computer is the same? Anyone have a write up?
the computer is not the same... even the external dimensions are different.
JR, KW, and a few others told me to splice the 2004 engine harness into my 1996 body harness, but my tuner shop told me it would be best to swap everything over, so thats what i did.
There are benifits to either way:
keep 1997 computer, harnesses -
cleanliness of swap. no random plugs not plugged in because 1997 cars dont have day time running lights (for example)
dash, gauge cluster, steering column, carpet, seats, etc. can all stay put, no need to pull the dash to replace all the electronics.
run 2004 computer, harnesses -
learn litterally everything about your car's computer system.
learn basic electrical skills such as reading wiring diagrams, sodering, splicing, and diagnostics.
learn how everything in your car is held together, turns out only 8 bolts hold in your dash board... lol!
faster computers were installed in 1999 and again in 2001 (if i recall correctly) these computers add to performance and reliability (theoretically speaking)
cleanliness of swap (although some things dont phsically fit "flawlessly" sitting at a car show and saying you used the entire 2004 computer system to ensure a reliable, safe, and fully functional swap will probably gain some bonus points.)
fact of the matter is, if you use your 1997 harnesses, you are going to have to learn to splice it into the 2004 engine somehow... if you use 2004 harnesses, you are going to have to completely disasseble your car and figure out how to make the little things work properly... either way, its a PITA.
as i said before, i suggest using your 1997 harnesses, as it will save you alot of time and headache working on your car.
