JG page 152 "Pink lead to coil wrapped in CLOTH TAPE 10" from center of firewall"

[Ron N.]

I just returned from the Lone Star Regional where I learned that I was missing the cloth tape wrapping on the pink wire. Can someone tell me the purpose of the cloth take. Also how is it configured, what wires does it cover or send a photo.

Thanks

Ron,
That was mentioned to me, as well. Haven't looked in the TIM&JG yet to see if it's there. Also, didn't note if there was any point deduction or just a "dot" for mention.

Leif, I didn't get a deduction on it but checked the JG and found it in the Mechanical section #16 Electrical. I would like to understand its purpose and get someone to tell me exactly how to configure it.

Ron,
Hopefully, someone will post a picture of a known good example. The paragraph you're referring to states "The pink lead going to the ignition coil is doubled back on the harness and wrapped with cloth backed tape approximately 10" from the center of the firewall. See details in Wiring and Clips below." There is no mention of the "detail" in the Wiring and Clip paragraph.

Lief and Ron- Only TI equipped cars have the pink lead wire enclosed in a white cloth loom, as well as the extra tape wrapping that portion of the TI harness to the remainder of the firewall harness. Standard ignition does not have either feature. Guess we need to double check the TIM&JG to make sure this is clear. Dave

And, clue the "mechanical" judges in, as well. Must have been a misunderstanding. Thanks David for the clarification...good to hear from a Master Judge.

The tape is clearly shown with part# and length for that area in the K66 Transistor Ignition Section in the AIM. As David said, non-TI ignitions did not use it.

BTW, if K66, there is another tape location. The Forward Lamp harness and the TI Harness get taped together using the same tape as they both pass over the sharp metal edge of the radiator support top bar on the left side of the engine bay near the horn relay. This tape is not standard vinyl electrical tape, it's more of the old type cloth based adhesive backed friction tape, outer surface similar to what is used on the TI harness wrap.

Is this the current interpretation??? Hopefully. The statement that the OP refers to is still in the JG ( 7th edition) with no mention of it applying only to TI cars. I spent a good deal of time trying to figure out what the JG was referring to, as my original harness ( non TI) doesn't have enough pink wire to double back and tape.

Thanks.

Rick.

David,

I looked again at this in the 1967 AIM. UPC 12 A8(standard wiring for NON-K66) does in fact show a 6" length of tape (Item #29) to be used for the Ignition Coil Pink wires to the forward harness along the firewall. Is this a mistake in the AIM, or in the JG?

For those of you that need the cloth friction tape it can be had at your local home depot, 3M makes it.

Re: JG page 152 "Pink lead to coil wrapped in CLOTH TAPE 10" from center of firewall"

Good to know we can get the tape at Homer Depot, thanks

I don't think that tape set up shown in AIM. UPC 12 A8 would work if U69 is added , would it ?

That's a good observation Jim. If not enough clearance, the Pink wires to the coil could be cut by the bottom edge of the Distributor Shield on a Small Block car with points ignition. Even a K66 optioned SB car would be susceptible if not enough clearance.

Jim, I think you may have the answer. I've been wondering why would a 6 inch piece of friction tape be specified here, when they were using miles of vinyl tape for almost everything else. Perhaps the worker who installed the plastic ties, etc on the firewall harness doubled the pink wires back and put the friction tape on ALL cars. ( not paid to think, just do it the same way every time.) Then later if it was a U69 car, the piece of friction tape was removed when the distributor shield was installed. Obviously this is pure speculation on my part, but it could explain why friction tape was specified vs the sometimes hard to remove vinyl tape. Great observation on your part.

Rick

Update: I messed around with this a little today and realized that with the distributor shield removed, 10" from the center of the firewall towards the passenger side, exactly as described in the TIM/JG is the perfect spot to double back the pink wires and tape them. They lay naturally at that point and look good. ( car is a 67 SB that has original/unmodified harness/pink wires with U69) Wire length from the taped location to the coil would be perfect. Problem is... there's no way to install the distributor shield if you do this. I thought about taping the pink wires to the harness closer to the center of the firewall than 10 inches, just for show, but there's really not enough pink wire length available to tape it anywhere and still install the shield. I feel like Jim and Richard have it figured out. No double back/friction tape with U69. If someone has a sb car with U69 and the pink wires doubled back and taped as described in the JG, please post some pictures.
