3.6 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 throttle body. 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 throttle body 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 throttle body 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 throttle body. Be sure the actuation arm “clicks” at the point where the throttle is wide open.
3.7 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.
