Need information on tach wiring.It has 4 wires Blk/green/orange/yellow. Also need to know exact location to mount on console. I also have a console vacuum performance indicator. 2 wires orange/ black with vacuum line. Looking for ideas where to mount gauges. Thanks..

From the 67 Dodge shop manual.

Black is ground
Green is points
Orange is indicator lamp

This shows violet, so yellow must be switched ignition power

On your vac gauge, orange is lamp (always on Mopar) black is ground
