Alright, first off, I'm not going with the typical OEM cruise control install. Stock parts cost WAY too much and I really don't like vaccuum operated modules.
What I am doing, however, is taking a cruise control off of a 98 Chevrolet Truck and installing it on the wrangler. I chose this module because they are common on trucks from 94-?? and I've installed several over the years. They are also inexpensive and are separate from the ECM, so all it needs is a few inputs and cruise works. I've already modified the module to adapt to the throttle body and found a good place to mount it.
However, here is where I'm running into problems. I cannot find a VSS signal to hook up to the cruise. On the wrangler, everything is controlled by the ECM, including cruise. The dash gauges are also operated through a data line (unlike the separate wiring in older clusters). Looking over wiring diagrams for the jeep, there are NO VSS outputs from the ECM.
So I came up with a solution, but here is where I need help.
Since the jeep didn't come with ABS, I would like to add one wheel speed sensor and use that to power the cruise. I already have a DRAC (Vehicle Speed Buffer) to power the wheel speed sensor and the cruise control module. So are the jeeps setup to have ABS even if they did not come with it? I believe I can install the sensor to feed the speed to the cruise control, so I can easily and cheaply install cruise.
My main question is whether or not I can install a Wheel speed sensor for ABS. I read that they use the same axles, so I should have a port to install the sensor, does it exist? And if someone could, I need a picture of the sensor in the front wheel so I know what to look for.
Thanks guys, I know my post was long.
