Title: Backup Wire Harness Retainer
Post by: Corey Bowcutt on October 28, 2020, 08:25:56 AM
I saw this part listed on the "Dead Nuts On" web site for a 68 Shelby Backup Wire Harness Retainer.  I know I have never seen one on my car so I feel like I need it but have no idea where it goes.  Can anyone shed any light on this hopefully with pictures?

Pete,

I recognized that picture so went to thecoralsnake.com to see more.  It looks like this is a transmission out of a GT500.  Is it the same for the GT350?  I am looking on my transmission for a tapped hole to mount this bracket to and can not see it.

I believe there is only one clip Ed

Same on a GT350 and a KR

The clip is under the existing bolt for the shifter mounting plate

If a C6, then retaining clips are different, in case anyone is wondering.

There is also a clip on the firewall. Not sure if that was Eds thought?

It is plastic and looks very similar ( in the shape of a check mark ) it hangs off a small nub, below the plugin to the main harness.

Jack has a picture of where this clip is attached to the transmission as part of his listing of the clip.

I missed that rockhouse66, not sure how.  But thank you.  It looks like below that was the firewall clip Pete is referring to.  Love it when a plan comes together.

350 doesn't have adapter plate on trans like 500. Typically I see the 350 clip on drivers side rearmost top cover bolt. Jack's repo is technically the 69 version. 68 very similar but slightly longer side leg

67 and 68 clip are the same. I figure that the people Spec Ed gave his original patterns to decided that they were so close in appearance to each other that no one would know the difference and so they made just the 69 style. They are so hard to find usable if at all it is a blessing that we have at least the 69 version available to use as a universal.

Tim,

This location makes more sense to me since my transmission did not look like the one in Pete's post or the one shown on the Dead Nuts On website as far as the forward shift mechanism bolt hole location goes. My forward bolt hole is tucked in closer to the mechanism basically covered by the lower shift boot.

I have 3 more questions:

1) The Dead Nuts On website says "For 1967-1968 Mustang/Shelby, you will need 2 wire harnesses. They get mounted into the first and last screw holes on the top of the transmission cover. They are installed with the bracket facing the top of the tunnel." There seems to be a disagreement as to whether to use 1 or 2.  Is there a consensus here on how many to use?

2) Which bolt hole locations shown in attached photo should be used for the brackets?

3) These look kind of tall, if they are mounted in this/these location(s) facing up do they really clear the trans tunnel?  I looked under my car and there just does not look like there is that much room?

Hi Corey. Your transmission will not look like the one in 'Pete's picture or Jack's website because it is not a big block transmission that uses the adapter plate therefore does not have the extra hole in the front of it
I have only seen one used on a 68 small block transmission. And it would go under the bolt that you have marked number three
