in a earlier post i mentioned that i called bowling green to find out about the cruse control campaign on the 84.because a other member mention it. well an other member said that bowling green factory desn't do that. i got a call back today fom the factory, and the lady told me the campaign is 84c22. it was for approx 49,000 84's that needed it done. well i called gm customer service and ask if this campaign was still active. they told me yes it is. the campaign sticker should be on the top of the rad. mine doesn't have this sticker. I'm going to call my gm dealer and have it done.so if you have an 84 that doesn't have this campaign done gm will honer it. sticker on top of radiator. campaign 84c22.

RELOCATION AND MODIFICATION OF CRUISE CONTROL SERVO

The relocation of the servo assembly is to be performed per the following procedure:

1.	After obtaining the service kit P/N 14091226, servo P/N 25074659, cable P/N 14091225, and bracket P/N 14091272 read the instructions carefully and familiarize yourself with the components involved.

FIGURE 1. FUEL VAPOR CANISTER AND HOSES

2.	Raise hood and disconnect the negative battery cable at the battery.
3.	CAUTION: The emission purge canister may contain liquid and/or vaporous fuel. To avoid potential for explosion during subsequent steps that may utilize an open flame or other heat source for soldering and shrinking heat-shrink tubing, the emission purge canister must be removed, vapor lines plugged and lower wheel house area ventilated in accordance with the following instructions (refer to drawings in Figure #1): Disconnect the two purge hoses from the steel lines at the frame. Cap and plug the lines and the hoses with supplied caps and plugs. Remove the canister purge solenoid bolt located on the canister bracket. Unplug the electrical connector at the solenoid. Remove the bolt from the canister mounting strap. Remove the canister from the vehicle. The canister drain hose at the bottom of the canister must also be plugged and removed from the vehicle.
4.	Remove air cleaner and disconnect the cruise control cable at the throttle and at the engine bracket. Cut and remove all cable ties holding the servo cable.
5.	Disconnect both the small and larger diameter hoses at the servo.

FIGURE 2. SERVO MOUNTING BRACKET

6.	Remove two bolts holding servo bracket to vehicle chassis and disconnect electrical connector at back of servo. Remove servo bracket and attached servo and servo cable. SCRAP ALL MATERIALS removed in the previous paragraph.
7.	Remove the smaller of the two hoses that were connected to the servo at its other end where it connects to a coupling tee and use the cap provided in the kit to plug the opening created by removing this hose.
8.	Remove the two outboard vertical brace mounting bolts located at the top of the brace near the battery. Position the servo bracket supplied in the kit over these two holes as in Figure #2 and use the original top brace bolt to mount the bracket. The cadmium bolt supplied in the kit must be used to secure the bottom of the bracket in order to supply a grounding location for the black wire on the new servo harness in the kit. Locate the grounding ring terminal on the new bottom bolt before securing the bracket with the new bolt. Tighten the bolts to the original torque of 20-27 N-m.
9.	Locate and mount new servo on servo bracket as shown in Figure #2 Press grommets in bracket holes and insert sleeves in grommets prior to attaching servo to bracket with screws and washers provided. Note that washers are to be installed between servo and bracket. Mounting servo on bracket before first mounting the bracket will not allow bracket to be mounted properly.

FIGURE 3. SERVO CABLE

10.	Attach servo cable provided in kit to throttle linkage and engine bracket just as the former cable was attached. Route the new cable as shown in Figure #3 to the servo bracket and connect it to the servo bracket and servo bead chain per Service Manual specifications.

FIGURE 4. SERVO VACUUM HOSES

11.	Cut smaller vacuum hose running from the cruise check valve to the vacuum reservoir and install the hose coupling tee provided in the kit as shown in Figure #4. Install the hose provided in the kit to the tee and attach the other end of the hose to the vacuum input port of the cruise servo.
12.	Locate the larger of the vacuum hoses which was disconnected from the original servo where it goes through the front of dash and re-route the hose to the new servo position. At this time, trim the hose between where it passes through the front of dash and where it will now be connected to the new servo. Make sure there are no kinks in this hose after installation.

FIGURE 5. JUMPER WIRE HARNESS

13.	Install supplied connector harness assembly by attaching connector to servo and installing rosebud in hole provided on servo bracket. Route additional harness down along vertical brace until intercepting the path of the hoses which run toward the front of the car. Route the harness along the same path
13.	(Cont'd) as these hoses located inboard of the left wheel well until they reach the previous servo location as shown in Figure #5. Use the non-restrictive plastic retainer along the vertical brace, and the five conduit clips along the rest of the routing.
14.	Locate the breakout position of the servo wiring in the forward lamp harness and take off the tape surrounding the servo breakout. Cut and tape back the black wire to the forward lamp harness. Pull the servo wires out of the convoluted conduit until they reach the splices on the new servo harness. Retape the original breakout position to cover the other exposed wiring.

FIGURE 6. JUMPER WIRE HARNESS SPLICE

15.	Cut off the original servo connector and discard. Splice the four remaining wires to their respective color mate wires in the new servo harness (supplied in the kit). Use the splice clips attached to the new servo harness, crimp and solder. Slide the heat per recommended practice. Cover the splices with the extra length of convoluted conduit supplied on the harness; see Figure #6.
16.	Recheck the routing of all cables, electrical harnesses and vacuum hoses and use cable ties where needed.

FIGURE 7. FRONT WHEELWELL SEAL

17.

Detach left front upper wheelhouse panel assembly from hood inner panel and clean surfaces (outer mounting hole area) of both panels. Apply continuous bead of body caulking compound (RTV) along full length of wheelhouse panel's top surface outer edge; outboard of mounting screw holes as shown in Figure #7. Attach wheelhouse panel to hood inner panel and apply additional caulk, as necessary, to properly seal gap between panel surfaces in areas both forward and rearward of mounting holes.

FIGURE 1. FUEL VAPOR CANISTER AND HOSES

18.	Reinstall the purge canister. Place the canister in its original position. Unplug the drain hose and route it through the clip on the skid plate. Reinstall the mounting strap making sure the canister is rotated to the proper mounting position as shown in Figure #1. Unplug and uncap the corresponding lines and hoses. Reinstall the hoses to the lines with the original clamps. Plug in the electrical connector to the canister purge solenoid and reinstall the solenoid and cover to its original position.
19.	Reattach the negative battery cable.
20.	Replace the air cleaner assembly and all attaching hardware.
21.	Road test the complete cruise control system.
22.	Install campaign completion label and release vehicle.
