Ok have my pot installed but have an issue when I turn it all the way to one side the check engine light comes on and the water in fuel and wait to start light!! Any ideas ???

And if you turn it all the way the other direction then set your cruise control it will accelerate til it it hit top speed - or nearly top.

You're supposed to adjust it about middle, go for a drive and see where your OD kicks in. Stop - turn it A LITTLE one way. Then try again. See if your OD kicks in later or earlier. That way you'll know which way is to increase kick-in speed and which way is to decrease.

Mine kicks in about 40. I leave it there all the time. If I want it kick in later, I just turn it off using the OD button on the gear shift lever....You did move the OD button to the gear shift lever didn't you??

Here's one way :

Real handy when you're running a POT and want to drop out of OD - saves having to reach down to the dash.
Be careful with the pin, the rest is a breeze.

The middle wire must always remain just that, the middle wire. So, when you remove the OEM TPS, and wire in the pot, the middle wire must still be the middle wire.
