1970 Convertible Restoration

Recommended Posts

Continued my wiring work.  Ran my starter wire (fed from trunk mounted battery solenoid) to a 250amp bulkhead connector into the passenger side fenderwell.  Then ran it through the passenger side behind the shock tower down to where the starter will be in the engine compartment.  Required hole drilling and some heavy duty rubber grommets.   

Also mounted my front power distribution terminal block.  Will be fed from main power block located at the top of the passenger side foot well.  This front power block will feed my 2-12" electric radiator fans (through a MIDI fuse), my transmission cooler fan, and my other misc items that will need power up there.

Thanksgiving meant grandkids showed up to help, but all they wanted to do was take the car for a ride....

Vic, you're not old enough to have a grandkid, much less three lol. I'm sure they were a lot of fun, and they will hold Grandpa up to taking them on cruses in the convertible once it is completed. 

I hope that you are taking notes and writing down all these electrical components, cause you can come wire mine if I ever get to that point. It's looking very nice.

HI Mike....I actually have 4 grandkids...the 4th one was at home, couldn't make it.

As an over detailed oriented engineer, of course I have built a spreadsheet to track all of my wiring terminations, as I will be using a lot of extra "boxes" in my build...   EFI computer, Dash computer, PWM fan controller, digital ignition box, power amp, etc, etc.

I have attempted to paste one page of it here, I would be willing to share it in about a week or so when I get it to the point where it is a working copy.    Pre-planning this really helps minimize the rework and rewiring, the number of splices/connectors, and having last minute loose wires laying around.  It also is critical if you have to do troubleshooting during power up of the car.   

  1. The first 3 columns are used to track the install.... R is routed, L is landed, T is tested
  2. The 4th column is the load/device which is to be wired up
  3. The 5th  column will list the fuse that feeds it (AAW does not provide this)
  4. The 6th column is the AAW circuit branch that the load is fed from
  5. The 7th column is the origin point of the wire that feeds the load
  6. The 8th column is the AAW wire number, or a simple wire number that I have assigned 
  7. The 9th column is the wire color
  8. The 10th and 11th columns are functional descriptions about what the wire does, like Gnd (Ground), BAT (battery hot all the time), KOH (Key on Hot), Switched (on/off)
  9. The 12th column is the type of connector used
  10. The 13th and 14th columns are key items, they show the "from" and "to" for the wire
  11. The 15th column is for any special interface with one of the boxes (VHX, PWM, EFI, etc)
  12. The 16th through the last column are how the wire is routed.  It shows the originating location, the route it takes, and the destination location.  I use this so I can consolidate the wires when I bundle and route them.  The abbreviations are for areas of the car that the wires go from-through-to
    1. UD - Under Dash
    2. FW Pen - Firewall Penetration Number
    3. PC - Passenger Compartment
    4. DFW - Drivers Firewall
    5. DRC - Drivers rocker channel
    6. PRC - Passenger rocker channel
    7. TK - Trunk
    8. etc, etc, etc.

Here is an example of where I am tabulating the wire interface between the AAW harness and the Vintage Air wiring.  Also some power distribution wiring here, which includes my trunk mounted battery and power points on the firewall and radiator support.

just curios as to where you're at. im planning on a cross country drive this summer and looks like you got the wiring thing down and im needing to get mine done. figured since they are both convertibles, have similar accessories and now your previous experience that it shouldnt be that hard for ya!

I currently have about 200 wires in my spreadsheet.    

Man, you engineer types are way out there :)

Now that is what I'm doing wrong. Instead of putting all the details down on paper like yourself, I instead think I can remember it all. No wonder I lose sleep thinking it all over and over.

I wish I had that ability, it's impressive the effort you have done.

I do solve lots of problems during those sleepless nights.

thanks for the comments.....this comes from my wiring experience about 7 years ago on my 1968, where I spent days chasing gremlins in my wiring harness. One resulted in a AAA flatbed tow back home....that was the last straw.....

Byron...I out here near Charlotte, NC, so always a cold beer and some wire ties here for you when you come by.  

My goal is to get the finished car to the Carlisle Ford Show in June, so we will see how that goes.

Vic,

  Nice work. I am getting ready to start installing my AAW wiring harness & would be interested in a "working copy" of the spreadsheet for my install.

Mike.

Hi Mike.  Will do.  I have been using it for about a week or so, and need to make some tweaks in it.   But it is a great tool for organizing the wiring to avoid double routing stuff from and to the same place.

Started wiring out some of the optional connectors that AAW has in their harness.  In this case, I am going to wire my existing power top wiring to a spot on the AAW harness.   The original install has a crazy installation with a 30 amp circuit breaker that is added on to the starter solenoid.  As I am hiding all my engine compartment wiring, I intend to feed my power top motor from a 30a feed on the new AAW fusebox.   I will try and add notes to the sequence of pictures below.   Used a simple sketch and then started wiring...

Firs Pic is my existing harness.  I intend to cut off the black plug (power feed) and power it from the AAW accessory connector.   Second pic is my sketch of the AAW accessory connector.  I am going to use the pink wire (#116) that comes of circuit branch #4.  This connector is "empty", designed to be used for aftermarket accessories.   The wiring kit comes with some connectors, but I picked up the AAW connector kit so I would have extra connectors.  3rd Pic is my sketch of the overall idea of how I will wire it.  4th pics is the AAW wire connector kit.   5th pic is the female connector that inserts into the AAW accessory connector on the harness.   This will be installed on a new wire I will use to connect the pink wire on the harness side of the connector to the black wire on the convertible top switch assembly.   6th pic is finished crimp.  7th pic is the 56 connector installed into the mating accessory connector.   8th pic shows how the accessory connector is put together.   

Next, want to add a plug on the other end of the red wire, and use that to connect to the black wire on the top switch wiring.  I don't want to use a splice, as I want to be able to install this later on in a "plug and play" way, as I will be under the dash, and doing crimps there is a pain.  So, I picked out a single connector assembly, and will be crimping and installing that in the next few pictures.  Last picture is the completed assembly.

So, after fussing with this for a day or so, my conclusion is that to start with, it is advantageous to have the lower dash out.   In my case, my car was stripped so it was a no brainer to start the wiring.   This allows easy access to the firewall holes that you need to route the wiring through.  

However, at some point you need to put the lower dash in, as that is where the wiring harness needs to go eventually.   

So, I put my pedal support bracket in, and laid the AAW harness on it, keeping all of the circuit branches up to, and including the headlight switch to the left of the pedal support bracket.    The rest of the harness is now laying to the right.   

What I will do next is to get my wiring organized so that I can route the forward wiring items (engine bay, horns, headlights, etc) through the firewall and in my case, the fenderwell.  Then, install my Vintage Air vent ducts, my VHX interface box & wiring, seal the remaining firewall holes and install my lower dash. Then hook up what I can and secure the wiring to the dash.   

The "Osborne" orange book has several really good drawings of what the factory wiring looks like. I chatted with AAW about this, and they tell me that for the 1969/1970s, they have tried to follow the original factory wiring layout as best they can.  

First pic is the orange book drawing, second pic is the harness laying on the pedal support bracket.  Last pic is a reminder that the 1969 and 1970 lower dash/steering column brackets are not the same, although at first glance they appear the same.   I had both in my parts stash, and quickly found out that I had grabbed the wrong one.   The one on the right is the 1970 bracket.

Continued on with my wiring stuff, this weekend concentrating on the interface with my Dakota Digital VHX box.

I had tabulated all of the wiring that needed to go to the box, so now I was searching for the source from my AAW harness.  To avoid lots of extra wiring, I am trying to maximize use of the existing harness and connectors that AAW supplies.  

First pic shows the AAW "F" and "G" connectors wired out directly to my VHX box.  If you are using the stock dash, these connectors go to a special dash connector supplied with the AAW dash package that connects to the original circuit board.   Or, if you have a custom dash (like Mustangs to Fear), then you can wire that out directly, following the AAW instructions.  The small connector with the 2 blue wires is one I made, it is use for the "Switch 1" and "Switch 2" functions in the VHX system.  These are used for toggling through the dash display and calibration functions. I think I am going to put these in my console, but for now, have a new connector ready to hook them up.

Second pic is apparently the proper way to route my convertible top motor wiring from the passenger side rear window factory hole/grommet, to the motor in the trunk.

Oh, some of the wires coming from the F and G connectors in this picture have been modified from the stock AAW configuration.  I will explain that in the next post.  For instance, there are purple and yellow wires used for a speed sensor, that are wired out in the AAW harness.  As I am using the VHX speed sensor, which has it's own harness, I have repurposed the yellow and purple wires for other stuff that the VHX box needs.
