Where do I look?
Hi. I'm helping a friend transplant a 2001 Mountaineer 5.0L into an early Bronco. We got it running the other day. Now I'm hooking up the cruise control that came from the 01 Mountaineer and need a speed sensor signal. We got a vss that goes in the speedo cable then found out that on the 01 Mountaineer the signal from the speed sensor is processed by the 4wabs module.
Sure wish I could find a company that makes a vss signal converter aftermarket that makes one so I won't have to use the 4wabs module to get a signal for the cruise control. Anybody know what to do here?
I found one forum that talks about using the GEM from a 2001 Ranger 2.5L to do this but not only are they hard to find but I'll need a pinout or wiring diagram for it so I can hook it up right.
Ideas?

vss
rostra makes one that hooks up to the drive-shaft it is made for their cruise control but I really don't know why it wouldn't work for you app
part #
250-4165
there are 2 on ebay right now just put part # in for search about 50.00 including shipping

I think I won't be able to judge weather that one will work because I don't know what signal is required by the 01 Mountaineer cruise control module. Square wave? amplitude? Sine wave? If I knew this then I'd have to pry this info out of a manufacturer of a vss. Then how to use a 2 wire vss when the cruise has a 1 wire input. Does the other one ground? Who knows?

my guess is that it would have a 12v + input and then the other wire would go to the vss I think it is just a simple magnetic reed switch you could also try banner

most speed sensors are just a simple signal switch that detects a pulse

you have 2 terminals I would check and see if you have voltage coming out of one
could 12v + or 5 v +
I really don't think they used a sine wave on this app I think it is a simple pulse
ford like to use pulse signals I have found that out on my tach on my conversion
so if it is a pulse then the rostra will work you just use magnets as the pulse
it probably doesn't really care what speed you are at just as long as it keeps the pulses within a the spec range so the more magnets like 6 would be a finer adjustment than say 2 magnets
I think you are trying to make it harder than it is look at a pulse instead of a sine
you could try a cam sensor off a ford and ground one side this is what seems to work on the tach sensors
that would be a cheap junk yard fix

On the left (referring to picture) is a "4-output vehicle speed buffer" used on vehicles with electric speedometers. It gets the vehicle speed signal from a 4 pulse sine-wave generator mounted at the transmission, and converts the sine-wave into a square wave signal for the ECM, speedometer, cruise control, and on some models, the radio (to control volume with the vehicle speed). 1990 and newer TPI engines have the buffer incorporated into the ECM, and the ECM outputs the square wave to the speedometer, cruise control and radio.

what are you using for your spedo to make it work could you pull the vss of that
I was thinking ford likes to use its sensors to ground so the sensor provides the pulse and the wave is provided inside of the cruise unit
case in point the rpm on a superduty we use the cam sensor and ground one side so then it reads resistance as a pulse
my glow plug light if I ground it then it comes on so it had to be ran through a relay
just a thought

We got a vss that goes into the speedometer cable and it produces a sine wave pulse not a square wave. I think a square wave pulse is needed by the cruise unit but I'm only guessing.
I posted a picture of the wiring diagram in post #11 but I don't know if it worked. I can right click it and view it.
I would try using a GEM from a 2001 Ranger 2.5L to convert the signal as I found info about on another forum but I can't contact the guy for a wiring pinout of the GEM.

Convert sine to square
how to convert sine to square
from my reading square is digital and sine is analog am I correct on this
you could always just buy a rostra and be done
