Anyone know where I can buy a replacement ECU wiring harness? All the connectors on mine were cracked and broken when I pulled my engine, and I need a replacement for when I put a rebuilt in there. I'm mostly looking for new/like new condition, but I guess anything will work.

 

Mazda Dealer direct $$$$$$$$$$$$$$$$$$$$$$$

Find some one on the forum...there should be a few for alot LESS!

 

which harness?
the front (from ecu to dash to the whole fron panel) or the engine harness?

 

Mazda or a junkyard, I don't know of anyone that makes a replacement harness.

The Mazda one is hugely expensive.. Junkyard ones, unless you do the work yourself, chances are some of the connectors will be broken :\ Especially 86-88s, those damn fuel injector and sensor plugs just crack if you look at them funny.

The one from the ECU to the engine. I already have the other one. Almost ready to put that guy in.

Bout how much $$$ from the dealer?

 

the harness is about $450-550usd off the top of my head the number is N370-18-05Z. at this point all he harnesses are hand made so you are paying for labor and the 30% mazdausa takes

$450 for just the engine harness? Holy shi@t! I payed $180 for the ENTIRE front harness (minus the engine harness) brand new. How can it be so goddamn expensive? Oh well, looks like ill find a used one

 

Try these guys:

Usually around $100

 

Thats where I got my full harness. I couldn't find the engine harness on there. Do you know where it is?

 

I can't tell you where to find one except for the junkyard. But I have a question for you....where the hell did you find that avatar, cause that *** is amazing.

 

its my ***, wait, never mind

 

go haltech!!

 

Send me $1k!!

 

that harness you got for $100 has a retail well over 1k

nice
good thing I got it cheap. Mine really is in dire need of being replaced.

 

You have no idea how hard I just laughed cause that is so true.

 

For some of you who have NEVER taken out the wiring harness to do an engine swap for instance....remember this quote, because Paul C is right on the money...

 

New mazda wiring harness in 2000 aprox $400.

cost me something like $130 for the mazda dealer to tell me that. Oh, then there was the towing bill.

ah...I don't want to talk about it anymore.

 

Bringing this one back but where did you find these harness's? Every dealer ive called says the parts are archived and its not possible to get them anymore.

 

I bought mine through russel automotive. A mazda dealer on the east coast. That was 3 years ago though.

If I were to do it again I would just make my own. It's just wires and some plugs. I found New fuel injector plugs are sold at autoparts stores. Most of the plugs could be reused.

 

But unfortunately, you have to pay a $50 sur charge If your order Isn't over $2000.

 

what does achived mean? just order it the pn# is up in the thread

mike

 

I guess archived meant that the part cannot be ordered anymore. But I was there yesterday and found the specific section of it I was looking for. 580

 

In the case with me, I need a new Front Wire Harness. The cost at www.mazdasurplus.com Is $180 US + surcharge of $50 + shipping.

This, In contrast to $2700 CAN + plus a massive discount of 20% at the dealership.

What should I do?

 

I'm Installing this behemoth tomorrow. I'm Impressed with this genuine Mazda Front Harness I received from Mazda Surplus. Even before It's Installation.

Thanks Icemark. I wouldn't have known about these guys If you hadn't posted the link. I saved big bucks...so I guess I kinda owe you one.

I'll post results when I'm done.
