Purpose
The FuseMaster 76512 will eliminate the necessity of
removing fuses for towing, then having to reinsert them for
driving. After the installation you will flip a switch to accom-
plish the same purpose.
This FuseMaster is for vehicles which must have two ATM
mini or two ATM micro fuses (not included) removed. If three
fuses must be removed, combine the FuseMaster 76512 with
one of the single-fuse versions — 76510, 76511 or 76513.

Safety Definitions
These instructions contain information that is very im-
portant to know and understand. This information is pro-
vided for
safety
and to
prevent equipment problems
.
To help recognize this information, observe the following:
WARNING indicates a potentially hazardous situ-
ation which, if not avoided, could result in property
damage, serious personal injury or even death.
CAUTION
CAUTION indicates a potentially hazardous situ-
ation which, if not avoided, may result in property
damage.
NOTE
Refers to important information and is placed in italic
type. It is recommended that you take special notice of
these items.
CAUTION
Read all instructions before installing or
operating this device. Failure to understand
how to properly install or operate the Fuse-
Master could result in extensive property
damage.
1.
Refer to the towed vehicle owner’s manual to determine
which fuse must be removed for towing.
Note: running changes may not be reflected in the owner’s
manual. ROADMASTER recommends calling the dealership to
confirm which fuses must be removed.
2.
Remove the access panel and then the fuses.
3.
Confirm that the two pairs of silver pins at the end of the
FuseMaster harness are the same size as the pins on the fuses
you removed. The pins must match.
CAUTION
Do not insert the fuses into the FuseMaster harness
until instructed to do so, or the fuses may blow.
Note: if the fuses are ATM micro fuses, you must purchase
ATM mini fuses of the same amperage to replace them — micro
fuses will not fit in the FuseMaster fuse holders.
4.
Insert the silver pins at the end of the FuseMaster harness
into the sockets for the fuses you removed.
Insert the two wires with red shrink wrap into one socket;
insert the other two wires into the other socket.
Gently press the pins down until they are fully seated.
Note: for vehicles with ATM micro fuses (for example, some
Honda models) press the silver pins to the outside edges of the
fuse socket — the sockets for these fuses have the connectors
at the sides.
5.
Test-fit the access panel, to ensure that it can be replaced
over the FuseMaster harness.
6.
If necessary, use wire ties (not included) to secure the
FuseMaster harness in place.
CAUTION
If the harness is not secured the electrical connection
may be broken, preventing the circuit from functioning.
FuseMaster will not operate.
7.
Look for a mounting surface for the switch close to the fuse
box. (The preferred location is on the fuse box access panel).
