I have a 1997 GMC 1500 6.5TD Truck and my? Is I want to put a ECM out of a 99-01 6.5 truck but the 99-01 trucks have the passlock 2 system and I don’t want to change out the steering column and the rest of the passlock stuff that goes with it. So how can I put the 99-01 ECM in without the rest of the stuff and bypass the passlock system. There is one wire that goes to the computer does anyone know what it is doing?

Not sure what happened there but will try this again. Right now I have a 1997 1500 GMC 6.5TD and I want to put in a ECM from a 1999-01 ¾ ton or 1 ton 6.5TD truck because the fuel rate is much higher more HP. But the only problem is that the 99-01 ECM is looking for the passlock 2 system and my 1997 doesn’t have all the passlock2 equipment. So how can I by pass the passlock II system without change the steering column and all the other stuff that goes with the passlock II system. The passlock system has one wire going to the ECM what info is being sent to the ECM and is there away to bypass the passlock II system right at the ECM computer without putting all required passlock II modules and wiring in with it.

One more time.
Right now I have a 1997 1500 GMC 6.5TD and I want to put a ECM from a 1999-01 3/4 ton or 1 ton. But the only problem is that the 99-01 ECM is looking for the passlock II system and my 97 doesn't have all the passlock II equipment. So how can I bypass the passlock II system without changing the steering column and all the other passlock II equipment. Is there away to bypass the passlock II system right at the ECM without having to put all the required passlock II modules and wiring in.
