Welcome to the forum enasnitsi.
You probably could bypass the bulkhead connector,
running from coil to cab.
Depending on exactly which model you have,
there may or may not be a fuse between coil and key.
Although the pink wire "hots" some fuses under dash,
it often is doing that in parallel and the fuse have nothing to do with coil.
Some models use an inline fuse between key and coil, look for one.
I would not recommend bypassing the bulkhead connector as first choice.
Try to find out why it's failing, if in fact it's to blame.
Is the whole connector coming apart and this is your warning ?
Think you would be more likely to have problems with the inside/cab side
of connector, especially around splice for key/coil/fuse.
That truck is one of the C/K vs R/V wire change years,
so I have trouble remembering the details. Should be easy to chase down.
Don't quit on it, you're doing a great job so far, keep going.
