Im assuming both of these can be wired the same. I opted to go with the Fullblown unit and have a few questions.

Instead of using a hobbs switch I would much rather have the AEM trigger the 2nd pump. I found the diagram below but Im having a hard time trying to figure out what output (pinout) on the AEM I can use or what would be suitable to use.



Any help would be greatly appreciated.

 

im using LS5 output.

 

Your wiring is right,use pin 51 (LS3)on ems then go to option ,configure outputs turn on the basic activation and function and you are set.
good luck.

 

Thank you very much

 

I just run both pumps at the same time, it makes wiring simple, and takes a failure mode out of the equation. I do not have a fuel pressure problem or rich afr using this method.
