Hi everyone.. I just bought a 1989 mustang lx 5.0, it is a project car and a lot of the wire under the hood have been butchered so I have no clue which ones go to the coil....what color are the wires or is there any way that I could straight wire the coil to the ignition? Thanks for any help

The wires that connect to the coil should be connected via a wiring connector that contains the two wires. One is red wire with a green stripe, the other is a green wire with a yellow stripe. This picture shows the connector at the very top. Disregard the rest

Only that the previous owner was a butcher. :(

Be prepared to replace the main wiring harness and possibly some of the body harness as well.

I can clearly see the correct wires that should lead to the ignition coil. Both have butt connectors on them, someone did a hack job installing an aftermarket ignition at one point. :nono: Pretty much the only reason to ever cut into those wires, although you don't really need to cut them to do so, but... :suicide:
