Can we do this? (aka The DIY Cruise Control Thread)

[Bravejus]

So I have an 08 LB 5mt. What will I need to make the cruise work. I want to go the homemade switch version. Do I need a certain voltage switch? The radio shack across the street has illuminated switches for 2.99 each. What resistors.

So I have to run a wire from the # 40 pin on the ecm to said switches correct? What about grounding etc.

I really want to have cruise this weekend. I have to start commuting 105 miles each way for work.

Brave I have an '08 LB MT too I would go the stalk method...you really need to know WTF you are doing to go the switch route, and there will be a lot of work involved. CTScott makes it sound easier than it is I'm sure, I run the electric grid for a living and am JUST following along with his LED and resistors method.

Im going the stalk switch route, however doing the wiring myself, like nickhjort, just need to find the time

If you use illuminated switches, you will need to power the lights from a separate isolated circuit (such as the interior illumination circuit).


Take a look at my DIY Cruise Control Thread for the switch and resistor info:

Basically, any normally open, momentary switch will be fine. The switches are switching 12VDC at negligible current.


For an 07-08:

In the Steps mentioning Connector D3, the blue (CCS) and brown (ECC) wires are replaced with a wire from the red wire of the switches to CCS on the ECM (pin #40) and a wire from the black wire of the switches to a ground point (a bolt connecting a ring terminal to the bare metal of the dash support structure for example).

For MT on 07-08:

The clutch switch (Toyota part number: 88280-14030) is required. A wire is run from each of the two terminals of the switch to the terminals of the under hood fuse panel connector shown in nickhjort's picture below (either switch terminal to either connector terminal is fine).

The 07-08 will not have a cruise control on indicator unless something like the module I developed is used. You can not simply use an illuminated switch, as the on/off switch is a momentary switch, which toggles the function on or off.
