Started laying out the wiring harness in my 74 duster wanting to make sure I have it right but my dads reference car was all done aftermarket and is using msd boxes. Looking for a couple picture of routing through the engine bay mainly at the distributor and how the temp wire goes up to the sending unit.
Also I have a small grey box on one of the two harnesses that also has what appears to be a vacuum switch on the circuit as well. Any Ideas?
