Default E38/T42 Computer Bench Harness

Have some extra connectors to make a bench test harness.

Attached a schematic drawing I created for what I thought should be the required connections.

Need to verify that I selected the correct pins.

Thanks,
Mike

Download our software, www.efilive.com then in the help tab on the V7 tune software, there is a tutorial that tells you pinouts and how to wire up everything for a ton of controllers. It is layed out very nicely. The software is free to download.

Thank you for the link!

The E38 J1X1 connector on your link indicates #13 for ground when the correct pin for ground is #73? Typo?

Why use the #11 Pin on the T42 connector for accessory serial power feed when you are using the 12 volt switch wire?

Mike

There are multiple ground inputs for the computers. It is easier to get the pins for the small 13 type. The t42 is easier for the computer to tell it when to turn on and off and reset. Just an easy thing more than anything else....
