In relation to John's (67gta289) and my continued pursuit for information related to the 1967-68 Safety Convenience System Article which we are trying to prepare for submission in the near (hopefully) future, we are requesting input from the readers of this thread.
Specifically, this involves the Low Fuel Light Proof Wire. For those who may not know, on early 1967’s, this is a Black wire that goes from the Starter side of the Solenoid, then down to the bottom of the Radiator Support, along the bottom of the support, then up and along the Driver’s side Inner Fender Aprons toward the Master Cylinder, then toward the Firewall where it ends with a triple female bullet connector that connects to a single male bullet connector at the end of a red wire that comes through the Firewall (see first picture attached). The sole purpose of this wire is to provide momentary power to light the Low Fuel Light to show that the bulb is working.
The Low Fuel Proof Wire as shown on the illustration noted above, is shown as Basic Part Number 9C877-A ; the complete Part Number, C7ZB-9C877-A is also shown in the January 1967 dated Parts and Accessory Catalog (MPC), and noted as 130.00” long. In addition, John has documented this “Proof Wire” on three 1967 Mustangs with Factory Safety Convenience Systems, all with build dates prior to January 1 of 1967, and all having the “Proof Wire” routed as described above.
Now for the problem ; in the 1967 Electrical Assembly Manual reproduced by Jim Osborn Productions, page E7-8618-3, Dated 1-16-67, and noted “Effective with CZV1-AF-510284” shows the “Proof Wire” as Part Number C7ZB-14N322-A, and now routed from the Starter side of the solenoid, along the Passenger side Fender Support to the.frewall. While this appears to be the routing of the “Proof Wire” on all 1968 models (for which we need confirmation), the question remains whether or not this Revision was implemented on 1967 models.
The “question” remains for several reasons ; 1) we have no documented examples of 1967 Mustangs with Factory Safety Convenience Systems built after January 1, 1967 ; 2) while the page (E7-8618-3) noted above from the 1967 Electrical Assembly Manual notes that it is effective with “C7V1-AF-510284”, we have not found how this number relates to a date ; and 3), we have found no TSB, Special Service Letter, Notification Letter, or any other Ford documentation as to when, or if, this Revision was implemented on 1967 models.
In summary, we are asking that owners of 1967 and 1968 Mustangs equipped with known Factory Safety Convenience Systems provide us the following information :
1967 Owners
1) The routing of your Proof Wire from the Starter Solenoid to the Firewall
2) Your car’s Build Date and Plant.
3) If your car also has Factory Cruise Control.
1968 Owners
1) The routing of your Proof Wire from the Starter Solenoid to the Firewall.
2) Your car's Build Date and Plant
3) The color of your Proof Wire (interestingly, while the 1967 Ford Wiring Diagram Manual clearly notes it as “Black”, neither the 1968 Ford Wiring Diagram Manual, nor the 1968 Electrical Assembly Manual show the color of the Proof Wire).
4) If your car also has Factory Cruise Control.
Your help in this matter will be greatly appreciated, as at least for now, it appears that this is the only way to find out approximately when, and if, this Revision occurred.
Thanks, in advance, for your help.
Bob
