Do early G's have different wiring ?

[craizg35]

I've been having alot of problems getting my Stillen blower to run as you may already know. I've tried resetting the E.C.U. and the V.I.S. and nothing happened. I also tried an OBD2 reader today. The only thing it ever said was "Please check the connections".

My G was made in 12-02 . The Stillen instructions said that I need to install a fuse tap on the fuel pump fuse.. no problem, but the fuse was in a different location than what the instructions said. Stillen's instuctions said that the fuse would be located at the top right of the fuse box and it was actually located at the bottom left??

I'm also questioning the power wire coming out of the E.C.U. plug because there is a little green light on the Stillen computer that should come on when the key is on. It has never been on yet...that I've seen anyway.

I really need to find out what each wire truely is on my E.C.U. plug on my specific car. I really don't want to rewire this thing but I don't think it's correct right now.

Were you certain to splice into the ECU harness with it facing the correct way?

I learned the hard way.

There is the FSM. Hopefully that can help. I'm at work, so I can't look through it right now.

When i get home i will post-up the entire harness diagram for you. I really think you may have spliced it upsidedown........I know....it sux.

Yes, the early 2003s have a totally different ECU altogether.

Mine was produced with a 07/02 production date and and I can't use A TON of programming options. One of the big reason I dunno if I'm gonna go FI.

yeah this really does suck...i purchased a turbo XS UTEC engine management system and had to return it because it wouldn't fit the earlier model 03's....i found this out after installing the map switching remote into my center console....oh well....good luck

every G made before the first half of the year in 03 is wired differently. after the mid year update they are all the same from then on....

I can verify for kevin. G35's built between 03/03 and 09/03 are considered 2003.5 models.

Only true on the Sedan. The Coupe has always had the newer style ECU.

Yup...the one truly retarded thing that Infiniti did
