The MAP, TPS, and Coolant temp all ground to the sensor ground
pins of the ecm.  Which may either be D2, or A11.
  Cordin to the sheet in front of me.
A11 for MAP ground on V-8+4.3 C,K
D2  for MAP on 4.3 + v-8 rvmpg

TPS, and Coolant grounds are
A11 for 4.3L+ v-8 rvmpg
D2 for 4.3+v-8 CK

Also C14 should only go to MAP+TPS

C10 to CTS

C13 to TPS

  Donor vehicle is a 91 Fullsize Chevy P/U with a 4.3
