I have been lookign for an hour and a half now and I give up. I am trying to wrap up the wiring harness on my 88 TPI swap into my 73 GMC pickup. I am stuck at the VSS and VSS buffer. I'f I'm interpreting my diagram properly pin A10 is an in put from the VSS buffer. I have a unit from Jagsthatrun to make the VSS signal but no buffer. Is this input necessary for the vehicle running and do I have to have a VSS buffer to make this swap? Or is there another way? I have all 88 IROC stuff TPI, Engine, computer etc. Please help!!!

 

need a buffer. if you find one at a yard its easy enough to wire up.
