2.17 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.
2.18 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.
