Crap... I shrunk the photo of the backside of the dash too much. Harder to see the details.
In keeping with the concept of a quick removal of the dash I build in 3 Deutsch connectors to carry all the signal and power requirements of the dashboard electricals. Attached here is the photo of the harness plugs (well... the two to the right) This is where experience (the lack of) with dealing with a higher spec. part (the Deutsch connectors) vs. a lower spec wire. The Deutsch connectors have accommodation for two different diameters of wire insulation for a given gauge of wire. Well... the cheaper spec. wire had a thicker diameter wire insulation than the Deutsch connector was designed for. Making a mess for me to get the wires to insert into the plugs. These plugs are designed to have the wires easily removed with the proper de-pinning tool. However, with this cheaper spec. wire removal/modification will be impossible. Additionally I did make a few mistakes (at the plug) which will make for confusion in the event of fault diagnostics. Also I didn't use the Deutsch crimping tool... I used my generic tool and it did not crimp it to the level of precision the Deutsch tool would do.
In addition to the "cannon plugs" (as my helicopter mechanic friend calls them) You will see a black box, and a switch with an orange backing. This is an intermittent wiper system taken from the 90's Ford F-series pickups, Broncos, and vans. I picked this up (from the dealer) years ago and had it installed in my TC. Amazingly enough it happened to hang around all these years to be installed into this car after I parted the TC. You would never know that the car has intermittent wipers by looking at the dash! Super cool factor... For me anyway.
As you can see the lack of detail/variety of colour coding will further exacerbate any future troubleshooting. I will be consolidating my build notes so that a future owner can at least have some idea behind the method to my madness. However, on a positive note the fuse box uses ATM mini fuses and this 20 fuse module nestles perfectly behind the tunnel cover out of sight, but is relatively easy to access!
