Will car not run? Will it advance or decrease timing if positioned ahead or behind?
A special tool must be used during the installation of the replacement synchronizer assembly. Failure to follow this procedure will result in the fuel system being out of time with the engine, possibly causing engine damage.
It is very important to coat the gear on the camshaft synchronizer with Super Premium SAE-5W30 Motor Oil XO-5W30-QSP or equivalent meeting Ford specification WSS-M2C153-G or equivalent, prior to installation. Failure to do so could result in gear failure upon engine start-up.

The PIP output is a 50 percent duty cycle signal that provides base spark timing information. The CID signal output is also a 50 percent duty cycle signal and is required so that the DIS module knows which coil to fire and for fuel timing in the EEC-IV processor. CID is high (VBAT) half of the cam revolution (180 degrees) and low the other half (refer to Figure 10).
