Remote Mount Solenoid Installation Instructions
familiarize yourself with any
wiring diagrams of your starter circuit
that you may have. On
the existing solenoid (mounted to the starter) there
typically three (3) terminals. Depending on the year of your vehicle,
either all or only two (2) will be used. Typically, non-HEI equipped
will use all three terminals, vehicles with HEI will
use only two (2).
The terminals on
existing solenoid are generally labeled �S, R, the B terminal is the
battery cable terminal and is not labeled�. The �R� terminal is used by
Non-HEI equipped vehicles and goes to the ignition coil. The
comes from the ignition switch and is a heavy
gauge (12 or 14) wire, check
you wiring diagram to verify the
color. The �B� terminal has the positive
battery cable plus
any wires for powering accessories, there may or may
fusible links in any of these circuits.
1. Disconnect the
positive battery cable at the battery. This cable may or may
to be replaced depending on where you locate the
remote solenoid. Use
zero (0) gauge cable if you have to
replace the battery cable from the
2. Find a
location for the remote solenoid, preferably one
that can be reached by
the existing cable from the battery (so
you can avoid replacing that),
but yet is still accessible
from the engine compartment should you desire
remote starter switches or other accessories, if it is accessible
then accessory hookup is very easy. Since most of the surfaces we can
mount to are plastic or fiberglass, use bolts with either nylock nuts
or lockwashers to ensure that vibration does not cause the solenoid to
fall off its mounts and cause a short.
3. Jack up
and support it with a good set of jackstands, NEVER
WORK UNDER A VEHICLE
SUPPORTED BY A JACK ALONE.
4. Disconnect each
wire from the existing
solenoid and carefully label which terminal the
mounted to. The harness containing the ignition circuit and other
wires that goes up over the back of the engine may be pulled up from
the engine and routed towards the new remote solenoid.
If you are careful
and plan the remote location well, you may
be able to connect these wires
to the new solenoid without
needing to lengthen them. Otherwise you will
need to lengthen
the wires to reach the new solenoid. Try to match the
gauge of the wires as closely as possible. While it is possible
to use crimp connectors on these wires, it is preferable to solder the
wires together and use shrink tubing to insulate the joint.
You can use
crimp connectors at the solenoid end of the wire.
5. Connection is
simple. First take the existing
(or new) positive cable from the battery
and connect to one of
the large lugs on the side of the solenoid, it doesn�t
which one. To that same terminal attach any other wires that were
attached to the �B� terminal on the existing solenoid. There should be
at least one, the one that powers the accessory circuit in the
6. The two- (2) small
terminal lugs on
the new solenoid are labeled �S� and �I�. To the �S�
attach all wires that were attached to the �S� terminal on the
existing solenoid. This wire will be the heavy gauge wire from the
switch. If there were any other wires attached to the
same post then attach
those as well. The �I� terminal is used
only on Non-HEI equipped vehicles,
if your vehicle used the
�R� terminal on the existing solenoid then those
be connected to the �I� terminal.
7. Purchase a new
length of #2 gauge battery cable with a connector at each end.
one long enough to allow you to route the cable
safely away from the exhaust.
Use insulated cable clamps to
hold the cable in position, if required.
Insulated clamps will
eliminate the possibility of chafing on the cable.
8. Now you must connect
a jumper from the �B�
terminal lug on the existing solenoid (mounted on
the �S� terminal on the same solenoid. This jumper must be
heavy wire, I am not sure on minimum size but would bet no less than
10 gauge would be okay, use soldered terminals on this wire. The kit from
Summit Racing Equipment uses a metal strap that connects the
All of these instructions
are from the
Summit kit which I found to be very well put together. I
recommend the Summit kit over trying to put a kit together yourself,
at the very least you get the metal jumper strap noted in step 8.
Finally, as noted
by \”Brian-74-454\” from the
Corvetteforum, the solenoid has to be grounded
Normally this is not an issue on most GM cars, as they are
metal and by merely mounting them you ground them, however that is less
likely on a Corvette. So be sure to ground the remote solenoid
frame or other likely location to ensure that the
system functions properly.
