DIY AEM Infinity SR20DET Patch Harness

[2_Liter_Turbo]

I recently got my AEM Infinity 6 ECU for my S13 SR20DET. I currently have a WS Pro harness for it (to go into my S14), but have found there are limited options out there for a patch harness between the AEM Infinity and the OEM ECU plug. So I've decided to give it a whirl in making my own harness. I've made some harnesses before, but nothing at this level.

I wanted to start this thread to not only document it, but also to see if anyone else has done so and if they had any tips or tricks. I have a manual crimp tool made for Molex connector pins already, and have ordered the ECU header connector from WS. I still need to order the AEM connector and of course, wire. Anyone have suggestions on wire or shielding?

Anyways, that's about it for now, hoping I can get some insight or suggestions while the parts get here.

Have you asked WS if they would make a patch harness?

I did. They aren't able to get to it until the end of the year, and I'd like to have this done by August at the latest. I just received the ECU header connector from them the other day though. Still need to order the AEM side connector though.

Old thread bump, did anything happen here?

I ended up getting a new harness with the AEM stuff already built in.
