INSTALLING THE BOOT
To ease installation of the
boots, use a drop of a dielec-
tric grease such as MSD’s
Spark Guard, PN 8804. If
you are installing the brass
90° socket style terminals,
slide the terminal all the way
through the boot, then grip
the terminal near the wire
crimp and bend it over 90°
and slide the boot down
(Figure 9).
If you build a lot of custom spark plug wire sets, MSD offers a professional tool, the Pro-Crimp
Tool, PN 3505.
INSTALLATION INSTRUCTIONS 3
Figure 5 Crimping a Dual Crimp Terminal.
STANDARD TERMINALS
1. After stripping the sleeve, fold the conductor
back along the wire insulation (Figure 4).
2. Do not allow the conductor to pull tightly
against the insulation. A small gap around
the conductor should be present before
crimping. Slide the wire into the terminal with
the conductor positioned so it is in contact
with the bottom of the terminal. Position the
wire through until the insulation protrudes
about 1/8" beyond the crimp tabs.
3. Position the wire and terminal into the "W"
groove of the Mini-Stripper-Crimper and
proceed to Step 4.
2 INSTALLATION INSTRUCTIONS
CRIMPING
To achieve the strongest crimp possible, it is
required to bend the crimp tabs over about 90°
using needle nose pliers (Figure 3). Follow the
instructions for the terminal you are using.
DUAL CRIMP TERMINALS
1. After stripping the sleeve, position the wire
in the terminal so the insulation protrudes
about 1/8" beyond the insulation crimp tabs
and the conductor extends about 1/8" past
the conductor crimp tabs (Figure 5).
2. Position the wire and terminal into the "W"
groove of the Mini-Stripper Crimper and fol-
low Steps 4 - 6 to crimp the terminal to the
sleeve.
Note: It is normal for the conductor to retract
into the insulation slightly as the sleeve
crimp is made.
3. After the sleeve is crimped, push the conduc-
tor between the crimp tabs and use a set of
needle nose pliers to crimp them together.
DO NOT OVER CRIMP.

4. Slide the other part of the Mini-Stripper-Crimper over the wire terminal and lightly press them
together (Figure 6).
5. Put the assembly into a vise making sure the alignment tabs are on the outside edge of the vise
jaws (Figure 7).
6. Slowly close the vise making sure the tool and terminal stay properly positioned and aligned
(Figure 8). Stop applying pressure when the terminal ends have wrapped securely around the
sleeve and grip the wire.
Note: DO NOT OVER CRIMP! It is possible to tear the sleeve of the wire by excessive pressure on
the vise. This will cause a weaker crimp.
7. Back off the vise and remove the wire from the Crimper. Gently tug the terminal and inspect the
position of the conductor to make sure the crimp is solid and firm.
