There is no wiring harness for a ford probe gt, so if anyone has ever installed a car radio into a probe gt, please halp me out!!!!!!!!!!!!!!!!!!!!!!!!!
heres what you'll need.....a test light (walmart like 3 bucks) or a diagram that tells you what each color wire is......and run the power, acc, and ground to the new h/u.....then run all new speaker wire for the new speakers or just hook it up to the factory wiring......not always necessary for a harness...unless you plan on adding the factory deck back in someday and selling it or something similar to that.....peace
