I Need This!!!!

anyone has a sr20 ecu diagram???? damn it..all i can find is for the silvias...if possible, please provide the info for a 1993 NX2000 wiring diagram. Oh..umm..yes, this is the early sr20de harness and ecu...heheh

I can dig out the wiring diagram for a P11 Primera if that is any good? I've got a horrible feeling that the wiring was changed though between pre-98 and post-98 ECUs...

Let me know if you want it and I'll scan it in for you :)

I have the engine and chassis wiring diagrams for a 93 NX2000 in front of me. What do you need to find?

I think he's trying to figure out how to hook it up to his DET because he is using "an early sr20de ecu and wiring harness" for his P11 DET project...

hwahahahhah.... ok, ok, I'll stop now luke.. I just hope tony sees this post, lol :D

aluke000...can you send me everything?
bb00gie...hehehe...i think the whole world knows that thanks to you!!! :D umm...the alldatadyi thing doesnt work...invalid user/pass?? did someone change it???

I just checked... it still works... did you use b-b00gie as the name?

Luke- I was just about to post this info - here I'm going to guess you've got one harness that may not mate up and one that's extra? Its for some wierdo emissions stuff, this is what I figured out for my swap project maybe it might help?

Theres a htm file with some wire colors and what they do.

May want to pick up a haynes book - its the only thing thats good for lol.... even my 2 FSM's (for a 98 200 my sis has now and my 97 fsm don't have wiring diagrams like haynes)

Best of luck luke.

Luke, looking for something like this?

Anthony do our 97 cars have different ECU's to say a 98-99 Sri ?

Hahaha yeah I saw it B-boogie...hehe

No - to the best of my knowledge, all P11 SR20De ECU's are the same. The P11 GT (with a SR20DE) has a ECU with different mappings, but the connectors etc are identical.

I think the difference that G22DET is talking about is between a OBD-I and OBD-II ECU. The later OBD-II ECU monitors more things, and will usually give a "Engine check" (MIL) light when you do extreme things like turbo'ing, whereas a OBD-I won't.

The OBD-I ECU's were on the early P10 Primeras, whereas the later P10 and all P11 Primera's have OBD-II ECU's.

Actually on the P11's over here the 99 ecu is different from the 2000+

So which one is better??? the 1999 or 2000+ So far I prefer 1999...which I have...

Sorry b-b00gie - I was replying to Neil's question relating to European P11 Primeras, and whether the ECU's changed through the years. Should have made it a little clearer what the hell I was blabbering on about :o

Not sure why you would prefer the 99... you mean the ECU or the car in general??

with the 2000+ ECU's there's no reset screw which is the only drawback...


As far as 99 vs 00+ G20's (based on stock form) I'd say 00+ all the way!!!


The 00+ are faster off the line do to improved gearing. They have 5 more ponies stock (big deal, but hey..) The roller rocker cams are also arguabley better. Also the MAF is bigger.. Not to mention the trunk release is now on the dash, waahoo!!! :D

trunk release in dash is sweet most peps cant find it when i ask them to pop my trunk:frog:

my secret plan..which NO ONE knows about..is finished...well, almost finished. the harness plugs up almost PERFECTLY with the DET motor...woohooo!!!

can you send that ecm diagram?, put in new sr20 into 91 nx2000.. no spark
