Microswitch Installation and Wiring (continuation)...

The bolts used to attach the microswitch have extra length to allow for spacing the microswitch away from the

bracket to offer a level of adjustability of the microswitch. After determining the position of the microswitch, we
recommend trimming the bolts for a clean installation.

Due to the wide variety of throttle linkage combinations in use, it is impossible to supply a microswitch bracket

custom tailored to each application. The universal bracket supplied will need to be modified to fit your specific
application.

Here is a microswitch assembly mounted for use. It

is an example of one of many ways in which to mount
a microswitch on your carburetor. The microswitch
bracket allows for many different mounting positions.
The microswitch bracket can be modified to clear
almost any potential interference around the throttle
linkage.

The microswitch bracket supplied is drilled to permit

many different switch mounting positions.

This

flexibility allows for the microswitch to be positioned
in such a manner to engage the carburetor linkage
without interfering with its normal and safe operation. The bracket may be manipulated (bent, twisted, and/or cut)
to best suit your combination. Mount the microswitch on the carburetor so the actuation arm is triggered by the
throttle linkage making sure that all wiring and the bracket do not interfere with the smooth and safe operation of
the carburetor. Be sure the actuation arm “clicks” at the point where the carburetor is wide open.

Final Electrical Installation Recommendations

At this time, it is advised that you double-check the following areas:

1.

Double Check 

all wires so that they do not come in contact with any heat sources like exhaust manifolds, and

EGR crossovers, etc.

2.

Double Check

the wires that lead from the microswitch to ensure that they do not interfere with the operation

of the throttle body linkage.

You are now ready to hook up your battery and prepare your vehicle to run.
