Hello everyone. I was looking for a wire harness and thought $300 was a bit outrageous for a boomslang. $200 for just an ECU extension patch was also a bit crazy IMO. Instead, I purchased an old ECU on ebay for $30 that had the wires still attached to it, like someone just took some bolt cutters to the wire bundle and ripped it out. I snipped off the connector from the ECU and hand soldered all the wires.
I'm following this diagram from here:

However, I'm unsure of what the "logger trigger input" wire is supposed to go to. Any thoughts?

Here's a picture of my masterpiece:

 

If I remember correctly, that goes to an external data logger, if you have one. Can't remember for sure.

 

Yep that logger wire can be run to your wideband gauge if you have one.
I'm gonna be building my own harness for the AEM EMS v2 since I'm not able to purchase it separate.

Buddy is giving me a hell of a deal on it and it's barely used.

Awesome. Thank you guys.

 

Here's a color coded ECU Pinout I made. Enjoy =)
