Yes, it's inline on the speedo cable, on the trucks that had cruise control.I believe the early trucks used the same system they had been using since the 70's, with a short speedo cable from the trans, a speed generating device on the end of the short speedo cable, and then another short speedo cable going into the firewall to drive the speedo. The one car I have seen with this system had the speedo generator sitting down near the steering column area under the hood.
On a project like this, you really need to wrap your head around how the system works and all it's little nuiances and little pieces and what they do. Then it's no problem going and getting what you need, you know exactly what you need. And then when you put it in and it doesn't work for some reason, you are on top of it and can troubleshoot it.Thank you! My local junkyard has a wack ton of 2nd gen Rangers. Is there a part list somewhere of what I would need to do the factory conversion?
The newer you get the more integrated things kit. Mine works with no engine input from a powertrain computer so it might work if the 2nd gen steering wheel switches work the same. I know the applifier looks very different between the two systems.On a project like this, you really need to wrap your head around how the system works and all it's little nuiances and little pieces and what they do.

1st thing to do is get a diagram like the previous post for your year truck. If you are having problems understanding it, post it up and we can talk about it. Apparently the diagram above is not for your year truck? Or will it work?
And that's also why changing your tail lights to (unloaded) LEDs will kill the cruise control- they don't have the resistance that the incandescent bulbs have.Brake Light Switch
The Amp has a wire coming from the brake lights. It senses the brake light voltage when the operator steps on the brakes and disengages the cruise control.
Note: The Amp is also set to look for a resistance to ground through the brake light bulbs. As a safety feature, if it doesn't see this ground, it won't operate because it thinks the wire to the brake light switch may be broken.
Bottom line is that if both brake light bulbs are burned out, the cruise won't work. I've seen it happen a few times.
