i bought a s5 jdm turbo front clip. On the jdm ECU there is a black box attached, it says mitsubishi and it has this number on it N374. what is it?

 

nobody knows.

stop bumping your threads, they are forbidden in this section and it makes you look like an immature, impatient child

 

It's a mystery. seriously..... the last guy that went out looking for an answer never came back!

 

lol was up with everybody i thought everybody suppose to help each other.

 

Seriously. Nobody knows.

 

maybe if you posted a pic someone might be able to help.

 

its black and it says mitsubishi N374. then it has this other numbers k8t11375. ill try to take a pic. also it is taping into one of the the plugs that go to the ecu, not the engine harness.

 

Yeah, I've got a little round thing near my Passenger side headlight that has the Mitsubishi logo... every time I see it I think "Oh I should look that up... " and never do lol...

So did Mazda use to outsource to Mitsu once upon a time?

 

yes they did, some mitsubishi parts are used on rx7s =]

 

Hmm...

Weird...

So if I needed (hypothetically) to get that part replaced, would I have to go to Mitsu or Mazda?

 

i honestly have no idea, but i would guess yes.

 

there is a black box by my ecu to and mine is usdm....

 

"hi i would like to get my 1987 mazda rx7 serviced please." -you

".................im sorry sir we dont have any record of that car existing." -mazda dealership

Or this situation might just happen

 

For a JDM part such as the Mitzu relay box he is describing you would go to a Mazda dealer in Japan.

It is not uncommon for Japanese manufactures to use parts from another manufacture. For example Nissans often have Denso (Nippondenso) parts in them, yet Nippondenso is one of the Toyota suppliers.

Mitzu is a big manufacture of industrial equipment in Japan. They build 50% of the alternators in Japan for all sorts of manufactures.

You guys do understand that just because a car is made by a manufacture (like Mazda) that they don't make about 50% of the car... that about 50% of the car is made by subcontractors and suppliers... right? You guys understand that... right?

For example Mazda doesn't make the CPU (the body computer) it is made by the same company that makes a bunch of the switches... Imansen.

 

its one of the body electrical components, factory amp, CPU. i wouldn't worry about it. you do need it however.

half the components and sensors in this car dont say mazda so that should not be a concern. my advice is take your time and label every sensor or plug you remove well. it will save you tons of time in the long run when its time to re wire.
