Wondering if someone could help me with the correct Routing of the positive cable on a 1968 442 with manual transmission. I know that it routes out the tube at the rear of the engine and down the valve cover over to the battery. My main question is how to route it coming from the starter. I see two options.

1) route the cable below and around behind the z-bat.

2) route the cable in front of and above the z-bar.

Which way is correct. Thanks!

Your pic isn’t the correct routing for a 68 with a MT. The tube is supposed to be nearly vertical (see Section 6-1, page 132). Although there isn’t a great pic in the assembly manual, I think the wire if supposed to run under the Z-bar as well.

You also appear to have your starter solenoid wire running through the tube and that isn’t correct either. (See section 12, page 133)

I’m not trying to pick anything apart that you’ve done. I’m just reading the 68 Assembly Manual as I see it. When the battery cable runs over the Z-Bar it contacts it. There’s no way around it. Eventually it’s going to wear through the cable. Also if you look at Section 6-1, page 127 you can see the starter wire under the Z-bar boss.
