2001 cummins 24v 5 speed I’ve swapped into a 97 single cab short bed Dodge Ram ss/t

i eliminated the harness at the 2 off-engine plugs and ran acc power through relay to give ecm power to run. 

I recently have purchased a edge comp box and tapped pump wire but engine makes no difference in power with pump tap wire plugged in or unplugged from box. Now here’s the real issue. I can’t remember the exact code off hand but it was a code for a pump solenoid and I believe it’s the pump metering solenoid the comp box taps into. What might be my issue here? I’m new to the forum as well. 

how sure are you that you tapped the right wire?  

 

Where did you purchase the comp from?

One of the few reasons I like the Stealth Plate over conventional tapping of the pump. 

 

Is the Edge Comp used? Is it the right series (early 2nd gen or late 2nd gen).
