I've replaced quite a bit of the "disconnect connectors" under the
hood of my 91 505 with ZDJL, esp the ones near the ex manifold. the
wires are also brittle, and some have needed replacement. Also the
female disconnects on the wires are impossible to clean, and the male
connetors on sensors , valves, etc get dirty. Since the sensors work
by resistance, corrosion can mess up the values.

Behind the alternator,
