HELP.....iv been serching these forums for the last 4+hours looking for rb25det ecu wiring diagrams and pinouts & also r32 interior to ecu (rb20det) pinouts,iv purchased a r32 4door skyline with A R33 RB25DET IN IT AND IT WAS NOT RUNNING,iv managed to get it driving by hard wiring the fuel pump and ecu strate to battery,now what i need is the brains of a member here to show me a thread that leads me to a idiots wiring guide rb25t into r32.
SUCH AZ,water temp
rev counter
fuel relay and prime
ecu to turn off at key via the wires beside air flow meter.

ok so after hours of of searching and trials and errors today iv got this far,just got a good full boost up road no poping or holing back.:D
THIS IS WHAT I HAVE FOUND WORKS TODAY
on the r32 engine bay side of the loom ther are a series of wires that used to power up the rb20det loom next to the powersteering pump and afm (air flow meter),the only wires i have used here are solid grey(in the rb25det loom powers injecters) solid white with purple trace(constant power) and solid black with red trace(ignition power).
On the ecu side (pasanger foot well) ther is the rb25det ecu & loom pluged up and the extra plug i call the body loom.
in the body loom find solid black with red trace,solid red,blue with white trace and white with black trace.:confused:

NOW...once you have found all wires named you will need to connect az follows,I WIL MAKE IT EASY 4 YOU :)

engine side body loom side
WHITE/purple trace>-------------------->WHITE/black trace
SOLID grey (injecters)^
NEXT

engine side body loom side
BLACK/red>----------------------------BLACK/red,SOLIDred & blue/white trace

i hard wired fuel pump to the relay in boot next to r/h tail lite,then earthd fuel pump strate to chassie,turns off and on at the key. will post up more as i find out the rest:thumbs::thumbs::thumbs:

R33----------------------------R32
Blue/Black ---------------->Blue/Black. Water Temp.
Yellow/Blue---------------->Yellow/Red. Tacho
Black/Pink------------------>Black/Pink. Fuel pump.
 
Well if you think about it buddy, people not replying. You've now learnt that a bit of research you will find your answers and now will probably understand/remember wiring more due to you, yourself finding out the answers etc...

Atleast you got it running. Wheres the pictures of the Skyline?
 
Whoow!! chill pill guys, the thread is only recent and people do have lives so no need to get abusive when your asking for help!

You said you would post pictures but didn't so its not like you have provided people with alot of information.

Also no need for the replies to be so harsh!.. its a drifting website yes but that doesn't mean there aren't some exceptionally technical and knowledgable peaople here who do this for a living!

Either way I guess you have worked out how to do it but 5 mins on google found me the wiring diagram for an RB25det
r33_gts25t_ecu_wiring.gif


and service and engine manual for the R32
ImportWorkshop.com :: Nissan Skyline R31, R32, R33, R34 <?php echo $maintitles; ?>

so you can work out which wires to connect with that and a multimeter if you really wanted.

Hope you get it sorted as it sounds interesting.

Brad =)
