S&S Cycle Electric Compression Release PN 90-4915 - Manual (Page 4)

2. Slide the supplied 4-foot black sleeve over the wire
harness until it reaches the connectors. Note that in
future steps you will need to cut the sleeve to allow
access for a fuse holder.
3. Position the harness so the compression release lead
wires are not being pulled tight. Once the best position
is found, zip-tie the connectors and end of harness
securely to the frame to prevent movement.
4. Using relay circuit diagram in Figure 1, locate on your
motorcycle, the wiring connection point shown on the
diagram. This will be between the starter relay and the
starter solenoid.
5. With one end of the wire harness already secured to the
frame, work out a routing position for the remaining
portion of the wire harness. Make sure the wires will not
be positioned where they may be crushed, cut, abraded,
or otherwise damaged by operation of the motorcycle.
The black wire will need to be routed to a ground, and
the green wire to power.
6. Find a suitable place to splice the supplied fuse holder into
the green wire of the harness. The fuse holder should be
mounted as close to the power source as possible.
7. Once the position of the fuse holder has been
determined, cut the sleeve at that position. Be careful
not to damage the insulation of wires inside sleeve. Save
the cut off part of the sleeve to protect the wires
leading from the power connection to the fuse holder
after the fuse holder is spliced to the wire harness.
8. Cut the green wire of the harness where it meets the
fuse holder lead wire.
9. Slide one of the supplied pieces of shrink-wrap onto the
wire harness lead wire.
10. Strip the green wire and one wire from the fuse holder.
Connect together with supplied butt connector. After
making sure the wires are held firmly, position the
shrink-wrap over the joint. Heat the shrink-wrap until
the joint is sealed.
11. Repeat the last two steps to connect the remaining green
wire to the other end of the fuse holder, if fuse holder is
not to be connected directly to power connection.
12. Install the small piece of sleeving over the green wire or
fuse holder wire until it touches the fuse holder.
13. Attach the green wire or fuse holder wire to the power
connection point shown on Figure 1. Use either the
supplied ring terminal or a connector of your choice.
14. Locate a ground connection for the black wire. Cut and
strip the black wire and attach either the supplied ring
terminal, or a connector of your choice.
15. Connect the black wire to ground.
16. Once all connections are made, use zip-ties to firmly
hold the wire harness and fuse holder in place. Again
make sure the harness has not been positioned so that
it can be cut, crushed, abraded, or otherwise damaged
by any operation of the motorcycle.
D. Operation
When the starter button is pressed, current is supplied to the
compression releases, which causes them to open. As long as
the starter button is depressed, the compression releases will
receive current and remain open. When the starter button
is released, current is no longer supplied to the compression
releases, which causes them to close. When compression
releases are open they bleed off cylinder pressure and make
it easier to turn the engine during starting. When the
compression releases close, cylinder pressure is contained in
the combustion chamber, and the engine will run normally.
