ECU Pinout cheat-sheets (large images, 1000+px wide)

*pmohr* · 08-26-2008, 07:22 PM

Some ECU pinout cheat sheets, if anyone's interested. All images are linked to the full-size versions.

I keep a few of these around (the A32 and Z33, both DE and HR) laminated in my box for doing EMS installs and the like. They're very useful laminated, as you can make notes and mark off spots with sharpie, then just spray it down with brake parts cleaner and comes out looking like new.

Didn't even bother with the '99, since I only have the FSM and no concrete pinout details.

If anyone has a pinout for the VG and VE J30s, I'll make up one for those as well.

Red is power, black is ground...

350z/G35:

'07+ 350z/'07+ G35 sedan/G37 (likely 370z as well, but not sure)

Very nice. Stuck for usefulness!

Do you have it for a 99max?

No, since the ECU pinout in the FSM is incorrect, unless someone cares to give me a link to a known correct pinout.

tlrmax · 08-27-2008, 09:36 PM

oh ok. I am gathering all my info b4 I install my mevi. I was wanting to know which is the rpm ecu pin for my 99.

Should be pin 5, like the rest of the A32s. W/G, IIRC.

Thats what I figured but my 99 shares many things with the 2000. Thats why I was curious.

As long as it has an A32 ECU and matching harness connector, it should be pin 5.

hi can u please tell me whether 06 nissan maxima j31 ecu pinout will be same with Z33de.
also where is the ecu located
thankyou

J31? What country do you live in? USDM 6th gen is A34.

pmohr, have you tried asking the Wiz about this? I mean he did install teh EU on his 99, so maybe he can help. just a thought...

What's KS?

duhhh... knock sensor... i'm an idiot some times

willie Hutch · 12-12-2008, 01:10 PM

Do anyone know where I can find a diagram for an 89 Maxima?

sorry if im late but i have help for you!!

it was a pain trying to look for it when i needed it

go to page 137-140 to look for whet you need. pic of ecu is on 140

Pmohr...Should the ckps sensor pins for a 1999 se 5mt ECU dated 06/08 be on point with the 95-98 or the 2000?

No idea. It's not like the 5th gen, it's an A32 style connector; the pins are just swapped around.

And IIRC it's only one of the CKPS', not both that are different.

Product_Of_Korea · 07-08-2009, 03:52 PM

according to dandymax's EU write up its the CKPS(REF). Instead of being pin 44(95-98) It should be pin 46(99).

Where can you get the schematics for the whole ECU wiring, what wire does exactly what?

The FSM.

*dukelubas* · 10-14-2009, 05:13 PM

Does the ECU receive a ground through it's mounting chassis/screws? or is it grounded through the harness/engine ground? Reason I'm asking, I'd like to run with the ECU not in it's chassis.

The ECU grounds solely through the two bolts on the LIM (well there may be some in the dash harness, never bothered to look).

If you've seen my A32 CEL video, my ECU is laying on the passenger side floorboard without issue.

Ok, so I might be off here, but what exactely does the pin-out cheat do for your car. In my case, a bolt on 2000 maxima from NY??

Not a whole lot by itself...

But it can be a very helpful reference when trying to wire up a V-AFCII, E-Manage, etc. for tuning purposes. Getting a good tune could be quite beneficial, IMO.

Indeed, that question confused me, to say the least.
