OK so I have to do the ecu swap since my nats is apparently "Broken" according to our wounderful stealership in London (SouthLondon Nissan) and would cost atleast $2000 to diagnose the problem.

SO

My questions after doing lots of searching and reading,

will I damage anything by just lifting up the white tab and pulling on the wires very hard? I've done it with a practice harness and it seems to work.

and

" Fuel Pump Relay - switch B/P wire from 117 to 11. " what colors are the wires for pin 117 and 11? (I think my 11 is blank but I'm not 100%)

 

Why on earth would you "pull on the wires very hard"? After you remove the white plastic cap, you simply unbolt it (one bolt) and the harness comes right off the ECU very easily. Pulling on the wires could damage stuff. Not smart.

Hes talking about moving the pins around for the swap. A pinning tool is ideal, but just make sure the white tab pulled all the way up before yanking on the wires.

 

That makes more sense.

 

the ecu is unpluged, I mean to get the pins out of the harness

sorry to confuse everyone... yes thanks !

 

Makes more sense now.

Just get a de-pin tool from RadioShack for ~$7

 

harbor freight has one also for about the same price

 

Thanks guys, but a bit of follow up

1) The fact that the all mighty wizard replied to this thread already makes me happy enough
2) I'll look for the tool at princes auto (Canadian harbor freight) tomorrow
3) Now about the color / pin blank question..?
