i just junked my 99 maxima and got a 97 maxima and put my 99 5 speed engine in it. the 97 was converted from auto to manual before i brought so it still has the auto 97 harness... i kno with the newer engines there are extra things for emissions so a lot of things on the harness are going to be unpluged and/or spliced...is there a write up or harness discription anywhere cuz ive been searching and looking on most of the popular maxima sites and cant find anything..let me know guys

 

I'm actually just finishing a swap of a '99 into my '97 I30. There was no splicing, but I had to use the vacuum galleries from the old engine so the sensors are in the right places and the hoses fit right.

 

if you keeping your stock ECU there should be no harness splicing as I recall, More Vac lines probably.

 

im using a 97 ecu

 

Then youu should be able to do what I did and just swap the 2 vacuum galleries. It's easy just a few bolts and you're free.
