P4876729 wiring help please

[NMike]

it is an MSD 6ALN. it has the NASCAR require weather pack connector. i had it running in my ramcharger years ago, worked fine. now i am trying to wire it in again. the colours are different a bit and the connectors are slightly off from the MSD instructions.

*heavy black/red +/-


*6 wire connector=

- red ignition 12v
- purple distr
- green  distr
- orange coil
- black coil
- BROWN

is the brown one for tach signal?

there is a single white wire that runs out the back of the box, but the connector still has untouched silicone grease from when i bout it new. i'm pretty sure i never used it on my truck.

Yes, brown is the tach signal.
