67 Shelby junction block

Hi to a 67 owner.The junction block is used to feed the amp gauge inside the car.Because it is a true amp gauge it is wired in series with the alternator.This means it will show all loads on the gauge,such as turn signals,heater fan,and headlamps will all show up as loads,and the needle will point to the discharge side of the gauge.This is normal.The wires are routed on the underside of the export brace and through the firewall to the pod that contains the gauges.Hope this helps sort you out.

 

Jim,
I will try and send you some pics....

Patty is right, it feeds the amp gauge...I will try to give you some info in the next few days...
I am at work..

I'm in Orlando....the picture is from Old Town in Kissimmee.......near Disney..

The Shelby American issue #39, has a very detailed article, which I have copied, for you about the gage cluster....Clear Spiral wrap, which you can obtain at Radio Shack, is used to hold the two wires together, along with two large white zip ties, which hold the wires to the bottom of the psgr side export brace....

if you have any questions provide your email address....

If your in Orlando on Oct 21...My Shelby will be in the Winter Park Concours D'elegance...Park Ave....downtown Winter Park FL...

 

Beware. Those photos are for an early car. The later ones had a black Juction block. I believe it came off of a Lincoln. And the wiring was different on the later cars. More factory in the covering, and no white plastic wrap.

 

Hey Roddster, what is different in the wiring on the later cars.....

The Junction blocks looks the same as the 69's..I used to own a 69 GT500...

The article states, the wiring was wrapped with tape, I do not recall seeing cars done that way, but this article was done in 1982!!!

On the NVSAAC.com web site, I found some pics of 67 GT350 #3086, which is close to Jim's car...

 

The picture of the 67 GT350 engine compartment submitted for use on the NVSAAC website is not restored very factory correct and I would not use it as a example to build by. The early cars used a gray 2 ear junction block as seen in the first pictures in this thread up to aprox 800 and the later 67's and all 68,69/70 used the C5VB -A 65 Lincoln terminal block ( Branda sells a exact duplicate of the later style). There were 3 types of covering used on the amp gauge harness.The early cars used the white plastic spiral wrap and then after aprox #1200 Shelby went to a taped wrap much like the other Ford harnesses throughout the car . The later cars in the aprox # 2400 on up range used a plastic sheath similiar to what you see on the door wire harness that goes between the door and the door post. I think I will mention that the Shelby headlight harness and tailight harness followed a similiar pattern with the exception of the early cars which didn't use spiral wrap on the head and tailight harness and left the wires flopping in the breeze in those areas until they evolved to the next stage. Shelby did not keep records for most of the change overs so the aprox numbers are plus or minus some based on observations made by myself and others.

 

My car (#2206) has black tape wrapped around the ammeter wiring.

A word of caution: if you hook up the ammeter you need to be aware that you are running a hot, unfused wire to the ammeter and back to the starter solenoid. If this wire or the ammeter ever shorts out there is a very good chance your car will burn to the ground. For that reason I don't have the ammeter hooked up.

The ALT light will tell you if the alternator ever stops charging so what purpose does the ammeter really serve?

 

Thanks Bob., and everybody else.....
These cars had running changes....

Jim,
I attend Old town, about once a month, when the weather is nice,,,I see you also own a '86 Buick GN....same here. I owned an 84 Buick GN when they came out, and traded it for my 86, which I still own,,,

Great car!!!

Jim, the factory Shelby tail light harness is as I described in the other post the regular Mustang harness it CONNECTS to has the weave material. The Shelby harness connects to the regular Mustang harness with 2 light blue butt connectors on each side. The regular Mustang taillight harness hooks under the dash and runs to the trunk were the taillight sockets are sniped and the Shelby harness connects. You can buy a nice repro Mustang taillight harness that has the fresh looking weave material and you modify it just like Shelby did. The headlight harness does not use the weave wrap. I hope this helps.

 

What are the correct type of terminals that were used at the junction block end and gauge end of the two wires? Color,style, and method of fastening? Does the original black and red 10 AWG wire have any print on it?

Randy,
On my early car, which you also have...the terminals are yellow crimp style, and I see no lettering on my red, and black wires, you can check out the photos, on the earlier posts....

Mark

 

Mark,
Yes, I noticed in your photos. So, would you say these are the typical Yellow crimp style connectors commonly used for automotive wiring? and do you think yours are original to your car?

Randy,
These are the originals, and the crimps are just standard yellow, for the correct gauge wire...If you need a more close up picture, I can provide one...

Mark

 

Mark,
Sure, would like to see a few shots if you can.
Thanks Randy
