Tach wiring Help

[thumper]

Hey Guys,

 

I am sure this topic has been answered before but through a search and looking at the wire diagrams I could not find out.

 

I acquired a oem tach for my 71 510. It is a 2 wire tach.

 

This is a pic I got from the site here that is the same of what I have.

 

So what I understand is I need to run a wire from the coil to the tach and then another wire from the other wire of the tach back to the coil.

 

So what I am trying to clarify is the white harness plug. That comes off of the bulbs. It looks like the same type of plug as the turn signal bulbs harness. ( The bulbs for the turn arrows on the dash. )

 

1. Where do I plug this into?

2. Do I run the wire from the + of the coil to the tach then run the other wire coming off the tach back to the - on the coil?

3. If I am correct so far. Does the + from the coil go to the male or female on the back of the tach.

 

Just want to make sure I wire it right. Any help is appreciated.

 

Thanks,

Dwayn

Yeah, That helps me out.

 

I guess I just need to find out where my tach/clock harness is.

 

Thanks
