I'm adding a tach to my truck and need a picture of the firewall(origional location) that shows where the tach wire comes out of the firewall to the hei,so I know where to drill the 3/4" hole on the firewall? Thank you

There is a series of dimples between the bulkhead connector and the E-brake cable hole as can be seen in the picture, (attached). The hole for the tach should be made using the dimple that is centered between the two larger holes.
