[T3] Bosch plug wire question on coil wire .

The two sets of Bosch wires I got seem to reach well enough though #1 could
be a bit longer at least it wouldn't hurt if it had 2" more. I just laid
them out so the longest ones where on #1 & #2  and they worked out , I have
them in the breather tongue then in the holder hidden by the oil bath. In
order to get the dist cap off enough to do points I lift them out of the
breather top flap rather than pull them out of the cap. I got one set in
2015 and the first set in the mid 80's and they look the same yet the ones
from the 80's have some nicks and worn flat spots on the outer grey cover
nothing that caused any issues .

 I'm pretty sure I have 1 and 2 in the right path from the cap over the
breather tucked under the breather tab then down to the one double holder
that's near the edge of the oil bath hidden with the oil bath in place then
outside and over the fuel line and outside of  FI plug for #1. They sit
away from the fuel injectors and fuel line metal manifold yet could be a
bit further away more like they fit on 3 & 4, Those are plenty long . The
shortest wire is #4 . I favored the cap booths so 1 & 2 face the right and
it was just enough where they don't touch anything probably why I need to
move them out of the breather to lift the cap away enough . I imagine Bosch
depending on when they were made might have changed the lengths a bit the
second set was made in Mexico. I would be easy to do as you did just keep
the short one and cut the others and screw on the plug end . I don't have a
great crimping tool for the cap or coil ends just a cheap all in one tool
that have one for 7 and 8 mm wire it worked well enough for one crimp and I
re used one of the one coil ends. Saw some on you tube you place in a vice.
The better ones would be the ratcheting type and new cap ends that are 90
degree. NGK has a nice set yet they are $75 to $80 . The Bosch sets so far
other than the coil wire have not been an issue seem well made and hold up
can't say I like putting them in the old holders I have to be careful and
lube them a bit them squeeze the wire so I don't cut into the outer jacket.
