I have been trying to figure out the mystery of why my car has died while i am driving. I have been studying wiring diagrams for 1966 mustang and tested like crazy. From the tests, i found that there isnt any power coming from the wire (wire 16) that leads from the positive terminal on the coil to the ignition switch. i repaired the wire and she still wont turn over. I am now looking under the dash see and see this wire. it just so happens that it leads to the ignition switch. it's been splice a few times and is connected to this intresting plastic set up.
my question is what the heck is this plactic thing?!?!
