ccs 100 in 2008 ranger tach signal?

I have been lurking and reading for a while but this is my first post.

I am installing a CCS-100 in a 2008 Ford Ranger 2.3 5spd.

I have located the VSS signal at ECM "center connector position 1"  PURPLE / orange (thanks to reading this forum) but can not locate a tach signal

I would like to get it from the ECM so the best answer would contain wire color/ ECM pin location (like the VSS location above)

The rest of the wiring seems pretty straight forward.

Thanks and great forum!

I have mine working and have the blue wire attached to nothing. The issue with not hooking it up is that using a VSS signal only on a 5spd could result (by depressing the clutch with cruise engagaed) an engine run away condition. Modern cars have rev limiters but............

Here is what I have found out so far (This a a few posts copied from a Ranger forum)

Unlike earlier years, it appears that there is no dedicated tach wire on 2007/8 between the PCM and the instrument cluster. If that's true, then the RPM data is probably transmitted from the PCM to the cluster microprocessor over the HS CAN Bus. (From a Ford Technician)

Thanks, as I suspected. I guess I'll be adding a clutch switch.

The cruise works fine with just a VSS signal but I dont like the idea of using the rev limiter as a safety if you happen to disengage the clutch while the cruise is engaged.

Looks like the Autometer 9117 would do the trick. It would cost around $80, which is about what I paid for the cruise in the first place. Looks like I will just be careful and disable it before resale.

Here is a link to the install instructions for the 9117 which explaines how it works, if anyone is interested.

I also checked Alldata and found that a Clutch "top of travel" signal exists at center connector pin 39.

For now the cruise works and I am gonna leave it be.

I will not be documenting this install on the forum as it is technically not "safe" without either a tach signal or a clutch switch.

Oh by the way. The center pin in the brake switch connector ( it is a 5 pin connector) is the always hot and the one closest to the firewall is the "on with brake on"

The problem you are likely having is the the crappy scotch locks are not designed for that small of a wire.

I cut the wires and used a butt splice connector (2 wires in one side and one in the other)

Do the trouble shooting procedure at the controller. The install manuel gives you expected voltage at each connector in each condition (on / off / key on / key off etc)

Follow this test and post the results if you cant figure it out. I can help you if I know these results

I called Audiovox Tech Support and they told me to tap the blue wire to any of the fuel injector uncommon wires. (These are the seperate wires that lead from the ECM to each fuel injector.

This makes sense. It will give the cruise a variable pulse based on engine speed and according to Audiovox, thats all it needs. A sudden increase in this pulse frequency (sudden engine speed up) will disengage the speed control.

This should work for just about any modern fuel injected vehicle!

Now back to Alldata to find the pin outs. I will post the results but likely wont get to test until this weekend.
