I just finished installing an OEM Cruise Control on my 2010 Regular Cab, 4 cylinder, 5 speed manual transmission that had no prewiring.
All went well except for a mishap with installing the clutch switch... The wiring attached to the top of the clutch switch is rather bulky. As such, and given the tight space around where the switch is installed, the wiring becomes all balled up as you turn the switch to screw it in place.
After screwing the switch all the way in, I noticed that the wires were twisted tightly together at the top of the switch. So, I began to un-twist them to gain adequate length to attach them at the proper locations. To my dismay, both wires broke off from the switch terminals at the top of the switch.
Thankfully, I was able to solder them securely back on to the switch. However, I used some new longer pieces of wire without a connector since the supplied connector isn't really necessary (See photo).
Here is a tip for anyone else installing the clutch switch:
In order to prevent this from happening again I folded the wires part way down the sides of the switch housing and secured them with electrical tape to provide strain relief if the wires became stressed by turning the switch to screw it in (See photo). In addition, if you haven't broken the wires from the switch terminals use a razor blade to remove the rubber shroud covering the wires and then tightly coil the wires and tape them flat together at the top of the switch (See photo). This provides a much smaller bulk for the wires and allows screwing in the switch without stressing the wires or wire terminals of the switch. (Use only one wrap of tape to flatten the wire coil. Otherwise, getting it off again will become difficult, given the limited space around the switch for your hands.)
Use this tip and save yourself some grief...
In Addition, since I just recently completed the OEM Cruise Control mod, if any of you folks have any questions about the installation procedure, just ask!
