I have a 1995 s10 ss but when i bought it the truck had a tbi wich blew up. my cousin gave me his old 4.3 spyder injection motor. I have the vortec wiring harness and his old truck was an s10 ss. Will i need a new computer. Also am i able to put a 1996 - 1998 computer with the obd 2 . I dont need my instument cluster becouse i will be using (or want to ) digital guages through torque pro. If i can use a 96-98 what all would i need.
