2nd Gen Fbody Gauges

As some may know, my Dad has a 81 TA with a LS/TH350 that will need some work. We have a complete set of electric autometer gauges that will go into the car.

My big question is wiring. I'd think it would be best to avoid using any of the factory stuff and run all new power/ground/signal wires for everything. The signal wires for many of the sensors would be new anyway since there isn't a point to repinning or redoing the factory harness to accommodate the different gauge and sensor. The only item working/connected is the tach and maybe the speedometer.

For water temp, I'm replacing the sensor at the front of the drivers side head with one that will work with the new gauge. Oil will get another specific fitting behind the intake to replace the current LS sensor. Volts should be simple and come off the alternator so that leaves me with tach and speed. I've read the instructions and believe this shouldn't be too terrible.

Any thoughts or ideas would be appreciated.
