back round on the truck. 1995 chevy s10 blazer eighth diget vin w waiting for a 4.3 motor. what motor years are going to use the same harness is my question. any help will do great

 

complete motors from intake to oil pan is 95 only engine block and heads are the same up to 98 any thing before 95 does not have the crank postion sensor to fire the distribter if your engine has top mounted spark plug wires on the distrubter the earlier 4.3 may work i dont know for sure if you look at car-part.com they have listings for what fits

 

thanks appreciate it.
