Kevin- the setup for the Imperial was special- never designed to be used in another car- but it can be!!!!

you need to figure out the wiring colors between the two. there is also a brake relay that needs to be used.

so the system needs- 1- left signal, 2- right signal, 3- common brake signal
from the dash area.

send me your email address and I can send you some factory wiring diagrams of the system.
