After careful searching I had to change my title and description since this may be old news.


I see that these are genuine AEM patch harness's. Maybe you've seen these before maybe you haven't - it was news to me as of poking around on ebay today.........

de-noob me a bit....
what does this do...why would I want one?

It turns potassium into vermacite which increases the turbidity of the bernoulli principle.....in theory....but in a labratory they have only been able to increase the viscosity of wolfram.

looks like an extension... so it would work with even the stock ECU in case you wanted to relocate it.

Or create a patch harness for an aftermarket ECU.

Why would I want a patch harness for an aftermarket ECU...

I'm curious because I think I may have a OBD1 Miata AEM EMS and my car is a 97(IE. OBD2)
In honda land, there are millions of OBD2-->OBD1 conversions... could this patch harness be similiiar to this??


Landrew - You have too much time on your hands (but I just jacked your thread so I don't mind)

- In the case you don't want to hack up your wiring harness in the car when running a parallel or piggy-back ecu. Also, if you have ever tried to do any sort of work on the ecu/harness underneath the driver side dash - the thought of one splice is depressing, much less 10+. For my 5' 8" frame, I had to lie with my back on the seat with only enough room in the footwell for my head and one arm. 2nd place to actual water-boarding. When the alternative is a pleasant splicing session on a workbench, sipping on the bevereage of choice - I'll take the $100 patch harness every time. FWIW, I got mine from Boomslang...

Sorry, I have been here for a few months and have learned a bit. I've still got a lot to learn but when I saw the oppurtunity to make a joke to someone in my position a few months a go I thought I'd go for it.

Notice though that I kept it clean.

Thats me.

squirrel - thanks! makes perfect sense now that think about it

Landrew - No offence taken!


Although now I'm on a search for a OBD2 to OBD1 conversion harness, or information on it.

I know this is an old thread... but just wanted to inform you guys so you don't waste money like I did. The AEM Patch harness sold is incorrect for the NA. It is the 3 plug patch harness that may work for the NB (or any obd2 miata that uses the three plug ecu).

That said... If you have an NA, go for the FFS, Begi, Boomslang, or the Autosport Wiring Harness.

Why wouldnt that work? The NA harness on the car side plugs into the two ends of the gray connector, and the two end white connectors plug into the ecu. That gray connector is the exact same on one my EMS4 harness.
