LT1 to LS1 dash
#2
from what i understand is that to put the ls1 dash in an lt1 car, you would have to have the body wiring harness thats inside the car and all other wiring such as the dash and the motor harness. I didn't have a doner car so when i did my conversion i sent my ls1 motor wiring harness off to get it re-pinned for a lt1 dash, cost like 500 or so, Im not good at wiring so i sent it off and paid the money. I think that the harness from 96-97 is different ccuz the 97 cluster is digital like the ls1's but im not sure. good luck with your build
