Lightbulb patch harness. where to buy ecu pins? s5? male and female. 3dprintproject

Thinking of producing s5 adapter harnesses.
Have a calibrated and extremely decent 3d printer. Would probably make ecu connectors out of abs plastic, but currently experimenting with other materials.

I know banzai makes them but I believe I can make them for cheaper, depending on the quantity/price of pins. This may be just a personal project, but if I am capable of producing products worth selling, I will do so.

Where can I find the actual metal male/female pins for s5 ecu? any links? is there just a standard size that I can find packages of them online? any help appreciated.

no idea, since i have never managed to find the harness plugs. the ones who have them keep the secret closely guarded because they don't want to lose the potential business.


ironic thing is the people who will buy a banzai adapter are less likely the ones who would bother building one, so they lose no business.

im assuming when you mean plug you mean the whole plug with XX amount of holes in it for connecting pins. I'm only in need of the name/type of connecting pins, as I should be able to make the connector plug.

But yeah been searching around years ago for this information and couldn't find it. will continue searching

meaning both, the pins and plug. since one is useless without the other so i start by searching for the plastic connectors, without that the electrical pins are moot. i don't have a source for the pins because i never found the plastic connector.

plus you'd probably be better off with an S4, since those are far more abundant and would be more profitable to make a PFC work with.

There are two companies who make nearly every connector on the FC, FD, and every other Japanese car on the market; they are TE Connectivity and Sumitomo. I'm not saying that is guaranteed to be your manufacturer, but they are you most likely suspects to start with.

You can find TE connectors and pins on Digikey. You will need a molex/weatherpack (this style goes by many names) crimper and if you plan on doing more than the 1 harness for yourself you'll want to invest in an expensive ratcheting crimper for precision, reliability, and efficiency.

I hope this doesn't come across as rude, but being that you don't even know when to start looking for pins/connectors, I don't think you'll be making more than 1 harness for yourself, if at all. Good luck.

i've searched AMP and TE electronics for days, nothing even remotely as specific as the ECU adapters have i come across. just generic and similarly proportioned universal housings, the ECU has stepped connector pin sizes throughout.

I only looked for a few minutes since I'm at work, but this appears to be one of the connectors, if not at least very similar to prove a point (I don't have an s5, simply going off Google images for what your guys are looking for).

TE, stepped sizing, same guides



Just for ***** and giggles, here's what appears to be the ECU side mating connector.

im more interested in S4 connectors, but apparently i don't know the correct terminology for searching the plugs.. it's easy as **** to get lost looking through 10,000 housing types trying to figure out what the hell they are trying to call a simple plug to plug housing. there is 100 different sub categories for plug types, and apparently even just that makes a big difference in the results.

Like I said, nearly every connector on the FC is made by TE

So I should just give up all of our sources for raw materials so that people like this can copy our product "cheaper". We are the ones that put countless hours into identifying the components, as you have found (and failed) yourself. We are also the company that put the R&D into developing the adapters. Sorry but this is not an "open source" product.

It has absolutely nothing to do with the DIY'er wanting to make a single adapter, those people just try de-pin their existing connectors or source used pigtails and most find that after 10-15 hours of comparing the FC to FD pinouts, they would have been better off buying the adapter in the first place.


To the OP, all I can say is good luck. I look forward to seeing your copy of our product.

nice try. i'm not the one selling **** to people that they don't need because i have a conscience whenever it comes to sales and it isn't just numbers on paper to me. want to streetport your n/a for $500? sure, we can do that! yeah it is totally worth the 2 horsepower gain...

so eat a dick.

I have no idea what you are talking about, but I did expect exactly that type of douchebag response from you.

Let's throw out a red herring, that has nothing to do with the product being discussed.

How about you grow up?

as i also don't know why you are so defensive over something you know that a DIYer will spend 5 hours building, admitted that most would actually just buy the jumper harness knowing the effort involved, which i said first didn't i? if someone wanted to copy it then they would have, those who have the ability to find the raw materials already can and do make the products.

the volume in this case is so low, i don't even know why we are arguing over it. maybe you sell a dozen in a year at the most, if i could care less about "copying you" then i'm sure most others will too. some people enjoy doing things on their own just so they can say that they did it, others may benefit from the information where they have a damaged ECU connector housing and need to replace it.

but don't pretend you haven't built off ideas others have presented on this forum of their own free will and claim you do all your own R+D.

I am not defensive at all, simply stating facts. You are the one that went on the attack (read defensive) for zero reason. Carry on.

Actually there will be no carrying on for if you want to continue this conversation then take it the private messaging aspect of this site and this applies to both of you. If either of you want to help the original poster then do so and if you do not want to then don't and it is that simple for this current argument helps no one and solves absolutely nothing.

there is some truth to this. i made my own, and i'm glad i did, but if it was for a customer i would have just bought one. it took too long to even re pin the FD-FD patch harness so it was S5 to FD, to make it worth it unless its for fun.

you should make the BAC valve connector, i believe its just an AMP budget connector, but in a custom housing, that is unique to Mazda.
