to over travel into the Park position.This will move the shifter into GM Parkposition and will damage the cable orthe transmission.STEP 20. On Ford vehicles, the neu-tral safety/backup light switch is lo-cated on the transmission (or on thesteering column on some early ve-hicles). If the vehicle has an AODtransmission the neutral safety/backuplight switches on the B&M shifter willNOT be used. The neutral safety/backuplight switch on the AOD transmissionswill continue to function normally.

On the C-4 and C-5 transmissions,

it is necessary to completely removethe stock neutral safety/backup lightswitch in order to install the B&M

transmission shift lever. On C-4, C-5and C-6 transmissions, it will be nec-essary to hook up the neutral safety/backup light switches on the B&MMegashifter. Locate and identify theneutral safety (the engine will not crankunless these wires are connected to-gether), and reverse light wires. Dis-connect the battery ground cable be-fore beginning to wire the neutral safetyand the reverse light switches. Reroutethe wires to the B&M Megashifter .Strip 1/4" of insulation off the wires andinstall the supplied slip-on terminals.Crimp the terminals onto the wiresusing a crimping tool or pliers. Con-nect the neutral safety wires to theLOWER switch and the reverse light

wires to the UPPER switch (See Fig-ure 1). Tape the terminal connectionsto prevent shorts. Reconnect the bat-tery ground cable, disconnect the coilwire and set the parking brake. Checkthe switch operation by attempting tostart the motor in each shifter position.The starter must crank only whenthe shifter is in the Park or Neutralposition. Check the backup light op-eration when the shifter is shifted to theReverse position. Adjust the switchesif required. Reconnect the coil wire. Goto Step 27.

STEP 21.If you have not already doneso, loosen the pinch bolt on the throttlelever on the transmission. This is thelever on the small diameter shaft. Prythe lever off with a screwdriver andallow the linkage to hang free. Removeand discard the stock shift lever andthe stock shift linkage. Install the B&Mselector lever in position and tightenthe pinch bolt securely (See Figure8). Make sure the lever is not pusheddown so far as to touching the trans-mission case. This will cause the leverto bind on the case. The lever shouldtravel smoothly from front to back witha positive click in each gear position.Install the stock throttle lever in posi-tion on the small diameter shaft asremoved and tighten the pinch boltsecurely. The throttle lever must oper-ate smoothly.STEP 22.Remove the two transmis-sion oil pan bolts directly below theshift lever. Install the cable bracket inposition with the two spacers betweenthe pan and the bracket (See Figure8). (If your transmission is equippedwith a cast aluminum oil pan thesespacers can be omitted.) Install thetwo 5/16-18 x 1.00" pan bolts suppliedand tighten to 12-13 lb.ft. Do not over-tighten as this can damage the pangasket.STEP 23. Route the shifter cable ac-cording to Figure 4. Avoid kinks andsharp bends and route the cable awayfrom hot engine or exhaust parts.

Remove the two rubber boots, one

large nut, and a large lockwasher fromthe threaded end of the shifter cable.Slide the end of the cable into the cablebracket. Install the large nut and thelockwasher loosely over the end of thecable. Install the two rubber boots ontothe end of the cable. Install the swivelon the threaded end of the cable andposition it in the center of the threaded
