you really should have started a new thread. There are several universal wiring harnesses both GM and aftermarket available depending on what whether using cable or electric throttle body. You should swap to electric transmission at the same time. The 4L60e is about the same length as the T400 you have now. You could repurpose existing warning light or add small LED.

I would install a 500 Cadillac engine in a Chevy truck but never install a Chevy engine into a Cadillac. Especially a real Cadillac. Hope it works for you.
