Hey all, just had a question in regards to my 20b swap in my 93 rx7.

Im looking at running an aem series 2 ecu, but id like the engine harness wiring done by a professional. Most of the shops I trust are in the states so it would be too difficult to bring my car to there shop.

I have the stock 20b harness, thats been cut at the uim. I would like to run the stock turbos non sequential, so I would need the 20b engine harness simplified. Then extended (from the cut point) to the aem ecu.

I contacted banzai racing, and was told they would need my car at the shop so they can make sure the harness is the right length. The only part where length would come into play is extending the cut harness to the ecu, which wouldnt be too much trouble to measure.

I then explained my situation and what I needed done in response to there last email. They told me if I thought it was that easy I should just do it myself.

My question being is it really that hard to just simplify the stock 20b harness and extend it? The only reason I dont want to do it is because I want a professional job, not that I feel its too difficult.

My last engine swap into the same car was a series 8 engine with harness and 16bit ecu. That was my first major wiring project, and although it worked without a problem, the quality was still lacking. So thats why id prefer a more professional job.

 

What is your problem? My exact response to your email was "If you think it is that easy then I guess you will have no problem doing it yourself."

Let us tell people what you really asked.

Hey, I saw you did some amazing work on your 20b swap, and im looking at getting a custom engine harness made for my own 20b swap into a 93 rx7 so I thought id give you guys a shout and see if youd be able to make something like this for me.

Im thinking of running an AEM Series 2 ecu, with M&W Ignition. Id send you guys my stock 20b harness, as well as some connectors (as my dash and body harness are automatic harnesses) to make it plug and play. Id be running the stock twin turbos, in non sequential operation.

Would this be something your shop could make for me?, as well, is there a ballpark figure you could give me to make something like this?

Thanks for your help.


My response:

We could build you a harness if your car were at our shop. We build custom engine harnesses in the vehicle, this ensures everything is cut to exactly the correct length.


Then I get this:

Oh I see, all I really need is just the engine harness to the ecu made, and then a small extension harness to connect the ecu to the dash. If I gave you measurements would you still be able to make something like that for me?

then another email:


To add, the only part where the length will come into play is extending my stock 20b harness (from where it was cut at the uim) back to the ecu using the proper connectors for the Aem ecu.

Then all there is to do is stripping down my stock 20b harness so that all I have is the connections needed for non sequential turbo operation.

Then I get this BS email, when I say I he thinks is is that simple he should not have any problem doing it himself.

Wow, thats the response I get? I know you guys do great work, thats why I went to you. Im looking for a professional job that will last. Yes I could do it, but I have more trust in your work.

Is it too much to ask to have you simplify my stock 20b harness, removing the unused connectors for sequential operation, and keeping the needed ones?


So lets recap. He has a hacked 20B engine harness that he wants simplified to a AEM and M&W, from a auto car with a bunch of miscelaneous connectors and wants to complain that I want the car at my shop to do the job correctly? Then comes on the forum to bitch that I wont make a custom harness for him? I can't bvelive there are so many DIYers that do not understand that DIY means DO IT YOURSELF.

 

Are you willing to pay for a an AEM s2 PNP ecu?
You do realize that you'll likely never see one available to the public right?

It just so happens, if you're willing to pay, I might be able to sell you an FD-pnp series2 box.
...should you really want it.


with that crap aside, by the Series1 box, move a few pins around and be done with it man.

 

I was thinking of running the accord series 2 AEM box. Id rather not go series 1 and mess with the ignition outputs.

Shoot me a pm though on your pnp box and we can discuss it.

 

Its funny when people want a hackjob stock harness instead of just buying a darn Haltech or Microtech...

 

Wait a min right there - a hack job?
You'll need to define hackjob..

 

Trying to salvage a 20 year old crispy half harness that's been cut. I bought one of those harnesses for the clips, was barely worth using those let alone let it control a 20b...

 

Mine are *not* crispy or broken. You're generalizing aren't you?

back on topic - who cares what this guy does?
who cares if he wires it all up with 18ga speaker wire?

It can't be worse than this pile of crap:

Not really, just from my experience with stock wiring.
Did I offend you? Because that was not the intention nor was "generalizing"

 

I never said anything against your shop when making this thread. I simply stated what I was told by you, and was curious if it really was as difficult as you were implying.

I never bitched about your shop, I simply explained what we talked about, and then went on to ask how difficult it was. Not once did I bitch saying you wouldn’t make harness for me, I didn’t complain about wanting to bring the car to your shop, I didn’t bitch about the emails you sent me. I simply stated the facts.

As I said, I want a professional job done with the wiring, thats why I contacted you. If anything Im implying that I think the workmanship of your shop is excelent. I needed some guidance in my build, and I thought id contact you because I thought your shop would have very good knowledge about the swap.

Anything about your shop that I had a problem with I wanted to keep to email, and just ask the local forum how difficult they felt it was. Instead, you decide to come on the forum and start attacking me.

So here was my problem with your response in the email:

1. The only problem you raised was in regards to the length of the harness. Nothing with connectors, my automatic harness, or my “hacked up” 20b harness (which all I said was cut, everything else was fine, not hacked at all). So I tried to go in more detail to help explain and hopefully clear up that issue, and instead I get an email from you that says:

"when I say I he thinks it is that simple he should not have any problem doing it himself"

Now to me this sounded like a negative response, implying to me well if you think its so easy go do it. You couldnt just explain to me more in depth just what the problem was?

2. As stated above, you couldn't just take a little time to help me out and explain the problems. Instead the very first response is a very general answer. I know your busy but instead all I got were short, general responses with very little help.

I have said nothing bad about your shop in my emails or when making this thread UNTIL you decided to come on here and bitch me out. I really don't see how I bitched about your shop once in making this thread, I simply explained what you told me and asked how hard it was going to be.

Your response to this thread and the issue was handled in a very unprofessional matter, not what I expected from your shop. That's why I was offended with your last email. But I didn't say anything against your shop, I've had nothing but good things to say until now.

All I wanted to do was ask the forum about my problem, since it wasnt worth your time to help me with my issues


And to clarify for jaggermouth. I wouldnt use my 20b harness if it were in the state imply mine is. I took a good look through it, nothing is crispy or broken. Thats why I wanted to use it. Its simply got a clean cut at the uim, so it only needs to be extended.

 

Why do I need to explain anything "in depth" to you? I told you the car needs to be at our shop to make the harness correctly, that is it, period. You want to argue that you think it is an easy job to do and that anyone should be able to do it without having access to the car, then you should be able to do it yourself, right?

Now you throw in that you want to use a Honda AEM. There is a nice gem that was never mentioned. All cars do not have the same pinout, you do understand that? I know you have gathered every bit of your ECU information from one thread. How about you contact the one guy that decided to use the Honda AEM and harass him about how easy this should be? Maybe he will just do it for nothing since it is so "simple". https://www.rx7club.com/20b-forum-95/what-standalone-20b-971608/

Good luck with your project, you are going to need it.

 

yo banzai what does a 20b harness for an fc run

 

Once again, you didnt say we absolutely need the car at the shop, you simply stated that the length would be an issue.

Im not arguing that its a simple job, im saying your making it out to be alot more complicated then it is.

As for the aem ecu, im not an idiot. I do know every ecu pinout is different. The pinout for the honda ecu is readily available, along with the harness to attach it to the ecu. If I was still going with that ecu I would build my harness from the honda ecu connectors and pinout.

I will admit, through reading that thread, and from past experience with aem I decided to go that route. There isnt much information out there, and as a newbie to the 20b I was looking for some guidance from a resident pro.

Im just suprised at the lack of professionalism, and your continued efforts to mock me. Thats all I'm going to say, instead of continuing on with this childish bickering.
