how do i go about the harness transfer from the 87 tc to my 87 mustang ? better to swap whole harness or to chop-n-splice? if its the latter how would i go about it?

Use your existing Mustang harness. It's just a few simple wiring changes to make it work. Here's 2 good links............................................

I used this one for my swap. Click on the link, go to 'Slugstang' then to '85 How-to's'.
