I have an 87 TI G-body harness, converted to TII and thrifted of unneccesary wiring ; you can use it on a TI if you wish and then it will be ready for a TII conversion
it is a 'known good' harness since it is currently on my 13.8 sec omni
I will include the 3 relays, EGR/Purge solenoids, MAP sensor & solenoid (underhood style), starter & alternator sub-harness, and power module but I have already sold my LM $40 + ship
I'm a good seller; check my feedback
