Look at the underside of the main fuse box under the hood and the diagram should show you the size of each fuse and the relays as well as the function of each. Other fuse boxes will also have the same information, but I believe the main fuse box has the ABS and cruise in it.

the IPM -- refers to the integrated power module under hood (fuse box) Fuse #36

Check your owners manual for the fuse diagram, and check the fuse

If you are talking about the cruise control, there is a cable that comes off of the throttle and into a mechanism on the firewall. It vaguely, somewhat, not really looks like a mushroom. This is the cruise control unit. There will be one or two vacuum lines in it. Consult your vacuum diagram under the hood to find out where they are supposed to go.

SOUND LIKE THE CANCEL SPRING FOR THE BLINKERS GO TO AUTOZONE OR NAPA WEBSITE PUT IN YOUR CAR INFO AND TYPE IN TURN SIGNAL SWITCH ? IT WILL SHOW YOU A PICTURE OF THIS SPRING
