Fiber Optic Wire
Does anyone know the correct length for the fiber optic wire that goes to the ashtray, the one I have in my 69 GTO is about 28 inches long and the new one I purchased from Ames is 20 inches. I called and asked about it, they referred me to call M&H and when I spoke to them they said 20 inches was from the GM blueprints . It does not make sense to me because the one that is 20 inches long will not reach from the top light socket to the ashtray. Can anyone tell me what the correct length is? Thanks, Marc

The 5/74 MPC lists the following: Panel Light Fiber Optic, 68-72 All A/F body, #6293310, guide ash tray light, 20 single wire.
However, GM makes modifications and running changes during the model year and maybe it was determined that a 28 cable was needed. M&H could be working off an original blueprint, and the MPC never updated and still reflects the original 20 spec. Not familiar with the 69 dash cluster but is it possible that the socket the cable attaches to should be in a lower position, though it has a 28 cable for a reason. |

The MPC shows the optic cable length as 20" as I show in post #2. Hopefully your comparison will clear up the reason the OP appears to have a 28" cable.

I cant see how this cable should be 20. I will not reach the top light socket on the top left of the circuit board if you are looking from behind the dash, unless I am doing something wrong and that is why I am asking. I would have thought this subject would have come up before, I am sure I am not the first person to order a new fiber optic wire. That is why I want to see if It was something I was doing wrong. Thanks, Marc.

Going over the '69 assembly manual there was a late model year change in the routing of the fiber optic cable (#8 in the drawing and parts listing) with the addition of a retaining clip.
However the fiber optic part number remained the same as before which is 20". EARLY LATE

Thanks Scott for taking the time and sending this detailed picture. I guess I am doing something wrong somewhere. I put the dash back in with the 28 wire for now and kept the 20 on the side for now. One problem at a time. I have to hook everything back up and see if the original problem is fixed. I think the wire to the coil was no good and the car would not stay running. Thanks, Marc.
