a friend of mine is trying to hook up a tst cr powermax.I told him everything I know, but I don't know what the blue wire is.I think it's the cool down wire.If so, can you run the truck without the wire hooked up?If you want , you can call Josh at 812-767-1901. Thanks!

Check Tst's web site directions are there to use if you want to. It is what I used to hook mine up and they were great.

"Note: The new timing Harness has a blue wire coming out with a slide-on (quick-disconnect/spade/tab) connector, see Figure 5. This is for the '06 Dodge Lift Pump Control Harness. If you have a '06 Dodge and you have a R49AP, then you will need to install a relay as described at the bottom of page 1 of these instructions in order for the Cool Down to work properly. If you have a '03-'05 Dodge, you can ignore it."

tell him to call tst when they are open. ive called down there and talked to mark (the owner) and he can tell you how to hook it up. instead of guessing and trashing something I would call him
