This seems to be the part of the project that most
people dread. When you start to consider a modern powertrain on top of this - it gets much worse than the seemingly
"simple" wiring put on the car in 1968. If you don't
understand electrical principals and know how to read and understand
electrical diagrams, this can be an absolute nightmare.
Thankfully we have a lot of background experience in electrical
wiring, so this should not be too much of a daunting task.
The
goal with the wiring is to retain the stock Mach 1 harnesses, and
modify them to suit the needs and the packaging on the vehicles.
The Torinos will retain the cruise control, fan control, fuse and
relay panels, ABS and traction control (still somewhat undecided),
fuel pump control, keyless entry and alarm system, A/C system and
most of the other Mustang functions. Everything not used on
the factory harnesses will be removed for simplicity and to reduce
the weight (as the harnesses are not light).
If you are going to attempt to do something like this yourself -
do not try anything without getting factory wiring diagrams.
Do yourself and get some factory manuals. These were both bought for $10/each of Ebay shipped.
