ECM went max retard on timing and wouldn't go into 5th as a safe measure.

Doing a little research the sensors rarely go bad, but rodents eating the wires is the main culprit. Off to HD I go to get the Milwaukee inspection camera I always wanted and sure enough the wires are cut. I usually garage my 4R but came home late and left it outside, temps dropped lower than usual and I guess they couldn't resist. Im lucky that they didnt chew the wires right off the connector, it should be easy to solder in some new wire. There is no sub harness for the knock sensors and I assume the dealer would want to replace the whole engine harness at $2478 so Ill be tackling this repair myself this weekend.

Pics to follow. Anyone know what specific type of wire it is? Shielded double coil is about the most info I could find.

ETA: Looks like I might have enough wire to just re-solder.
