swapping out tbi harness for tpi harness

Hi I am in the process of installing tpi in my 91 rs Camaro,Can any one give me tips on the best way to remove and replace this harness ,what is the routing does it go back in to the dash area.Where does it all go to. I am using an 86 corvette L98 and computer and a 87 Camaro tpi harness.Are there any other wires that I may have to change it being a 91. Any tips or help is appreciated. Thanks Mike

Yes, several wires need to be moved. Find a pinout of the 91 C100 and C207, then compare to the 87 C100/C207

Why not use a 90-92 TPI harness/ECM for a plug and play install?
