trying to get the check engine light off since the I did the swap and got it running smooth now the plugs on the vac pump a little different put they both have 3 pins, the 02 has 4 pins but only 3 are used.on the 02 3.7l it has pin1 has nothing,pin2-generator source,pin3-pump switch signal,pin4- solenoid control
04 hemi pin1-ground,pin-2 switch signal,pin3-solenoid control
I have pin(this is how I pin them pin 02 3.7l=pin 04 hemi)pin3=pin2 pin4=pin3
according to diagram plug pinout on the 02 pin2 is generator source and on 04 pin1 is ground do I run a relay so when I turn the truck on it'll have +voltage and just ground the 04 pin1 to the frame here all the info I got I dont wont to change the canister if I dont have to save a little money I can just cut plugs and solder them together
