When you use a Hotwire or other type harness, does the computer show a vss speed? If so, what does it use to read? I used a 04 ram 5.7 and a 545rfe trans from a donor. The harness is a stock one trimmed down. I do not have a vss sensor hooked up on the rearend. But when I look into hooking one up, it looks like it goes to the abs module then a bus signal to the ecm? I’m using the output shaft speed signal to an auto meter speedo. But I put a decent size cam in the motor and it doesn’t transition from driving to idle well. And it shows 0mph all the time.
