cut, splice and soder my friend lol
Same wires diff plugs ?
Did that for my mustang, Had GT500 HID's that I took out before I sold it and then spliced and wired them into the GT. Work perfect not a issue.
If its like the 05-09 the harness is completely different and had relays built in for the hids. I just did this and even having the correct harness i still had to solder in 2 diodes for them to work right
Yup sort of a pain in the aas
There are how tos on how to convert the harness to hid but i would look into just buying the harness
Caleb install them just a little bit of wiring I put the factory gt500 hid in my car and wasn't bad at all
