1989 GMC Safari
I had my Safari parked idle for about a month. It was in perfect
running condition when parked. When I started it, it would barely run
and the "check engine" light was on. I tried to check codes by jumping
A and B under the dash and only recieved code 12. Normal. I saw that
mice had chewed through 2 spark plug wires and the coil wire. I
replaced them, but found the wire in attached photo chewed through and
could not find where this wire goes. It is missing! It is a grey wire
that is the ONLY wire external and pulled back and taped to a wire
bundle under the hood behind the accumulator just before connector PED
2. I would appreciate if you could tell where this wire connects or
send me pictures to firstname.lastname@example.org.
Man those are some voracious mice you've got there Barry. I've never seen
mice eat a hunk out and take it away with them.
How is the vehicle running at this time, since replacing the plug wires and
coil wires? You might want to check a Chilton's manual for the wiring
diagram to see where the grey wire goes. Most local libraries carry
Chilton's or a like manual. I've never had any luck finding free on-line
wiring diagrams, but your mileage may vary. Alldata.com is a really good
resource. It costs $25 per year, but if you do your own work, you can save
that much with just one repair, and for some of the harder things to get
ahold of (like wiring diagrams), it's really worth the price.
I do know that a grey wire is used for the intermittent windshield wipers,
but I'm not sure if that's what your grey wire is. You might want to check
the operation of the wipers in all modes. That's something of a stretch
though, because other circuits use grey as well (fuel pump for one, although
that is typically a smaller gauge).
BTW - you would be better off next time, to post a link to your pictures
rather than post them to a text group.
