Approximately a year ago my lift pump(Raptor)quit working because my ECM was misbehaving(WTS light only working part time). I hot-wired lift pump through a switch as I needed truck. I have since had ECM repaired and all is good, however I would like to know what the folks here would suggest I do with lift pump power.

Should I hook it back up to ECM, through a relay of course, or should I use @IBMobile ASD wiring article for lift pump power? I’m kinda apprehensive about hooking to ECM again but that would be simplest. 

 Thank you in advance for your suggestions. 

I'd go to ecm if it's working again. It's only using the voltage to power coil on the relay, just make sure to use protective relay that had a diode or resistor built in, most aftermarket pumps come with regular cheap relay.

IBmobil mod is great too.

Do @IBMobile lift pump relay mod. I did. Have you done the W-T  ground mod yet?

I was going to go the ASD route, but the idea of tapping into a perfectly good wire while my ECM still has a working lift pump circuit didn't appeal to me. Just tripping a relay, there's no real risk of taxing the ECM.

I just don’t want to go through the bad ECM but I guess there’s no guarantee either way. 
Thanks guys
