Upgraded (red) positive cable routing to starter solenoid

[mja]

Hi,

 

I'm trying to route the Red + cable to the starter.  Trying to understand the instructions.  Should I cut off the grommet on the engine shroud and try to fish it through that hole?

And then bolt it on top here?

There are a couple of options:

1) Just above the starter, you will see where the original cables go through a rubber grommet/bung in the engine tin.  If the engine were out of the car, you can remove the original red cable and route the cable as per original.  

2) If the engine is in the car. you can make an additional hole in the engine tin just above the top of the oil cooler. This piece of tin is removable for making the hole.  Behind this piece of tin, there is a grey fibreglass oil cooler duct which is separate to the main engine shroud.  The hole should go through this part as well.  The cable then passes through both parts into the shroud and 'appears' above the oil cooler.  It ends up resting on a metal piece of the oil cooler duct.  From there it is an easy route to the alternator.  Use rubber grommets to protect the cable.  You can leave the original red cable in place and connect the new one to the starter in parallel as per your picture.

I have read these instructions several times, but I simply cannot understand the process. My engine is still in the car, and I cannot get the current rubber grommet out that the original cables run through the fiberglass engine shroud. How do I run the new heavy duty cable to the solenoid (without destroying the engine shroud) and do I keep the current power line and ground line and add to the new 175amp alternator(in addition to the two new lines)? Thanks!!

Nothing to do with the shroud.  The grommet referred to is at the very front of the engine above the starter motor.  It is wedged into a piece of the engine tin (which is removable)  You need the car on a ramp ideally.

You can see the rubber grommet (block?) top of this photo on the right side just above the grey oil cooler part of the shroud.  The simplest way is to make a hole through the tin and the grey part.
