Thread: are the ecu pins the same between the b13 and b14?

This is the closest you get from me right now. This is Nissan 4 cylinder blue plug, OBDI.

AEM's PDFs have pin-outs and visual displays of each plug if you just want to look it up that way.

aahheeemmm lol

lol or eric thought of it. and im trying to implement lol

i have b13 ecu on my desk right now, and i have a white b14 harness plug sitting here

I have both here, let me check tonight.

So what exactly are you asking? Will the pins fit from the blue ECU harness plug to the white one?

What really need is a ecu plug cut off a obd1 car. Looks like in going to the salvage yard tomorrow morning. What I want to do is repin my 98 to run a b13 ecu. But the question is does the actual pins inside the ecu plug fit inside the other connector. At a glance it looks like the b14 harness has a few that are larger style. If that's the case its not that big of a deal either cause I can use some of the pins that Aem supplies with there ems to convert those over.

Stay tuned I will get it all figured out and make a write up on my 98 and possably my friends 97

That's what I understood it as.

they are different, there's like 18 that is the same size and the rest is different.

edit: yes i am talking about the pins. IIRC the B13s are much bigger then the OBD2 ecu. it's been awhile since I checked. I use to have the part # for the Pin's from Digikeys but a step down would be easier for me.

I do know the ODBI setup has "small" and "large" pins at least.
