Default Spark PLug wire position?

On my '88 C4 Im about to change the spark plug wires. My ? is in the haynes manual theres a diagram with the layout of thr cylinders and what number each is. Theres also a pic of a distributor and it says the blackened terminal is the number one spark plug wire position and theres an arrow going clockwise. Im assuming that since its going clockwise that its in order starting with the number one sp position? As in 1-2-3 and so on around clockwise til ur at 8?

Bottom = front
The distributor orientation may not be right but the cylinder numbering is correct.

Followed up with a printout, lamination, and a thumbtack to the garage wall.

It depends on where the valves are. A bit of predetonation can destroy an engine. But if the spark is way out of phase then probably nothing too bad if anything would happen.

The pic I posted has #1 at about 6:30. Rotate that in your mind's eye counter-clock-wise to 5:30 and you've got the HEI positions.

Move them CCW one position 1 goes where 2 is 2 goes where 7 is etc.

(The diagram that I found was for the older points/cond setup.)

Ok gotcha.
By old setup do you mean as in an older car? Is there any difference between that and the hei setup besides the fact that their positioned differently?

Yes I meant in the out moded points and condensor ignition system vs the newer HEI system. For the purposes of the diagram that I found there is no other difference.

If you save the picture, then view at a larger size, it may be easier to read. I wouldn't worry about asking questions, everyone has to start somewhere and not all are familiar with the ins and out of this bulletin board.

Everyone was a newbie here at some point.

Yeah but depending on the position and condition of the clips, that can be a pain in the neck with the factory routing, I couldn't get my beefy hands to the factory clips doing it one wire at a time.

Remove the fender panels for easier access to the wire holders/separators next time. They're held in place with 10 mm bolts.

I probably will next time, of course I found that advice after I had bloody knuckles Even doing that I still label each wire with its cylinder number with masking tape. Takes five seconds a wire, pulls off quickly and stays out of the way. Of course I'm one of those nuts who has labels on every damn bolt and piece I touch. That way I know what the big pile of "extras" I have in my garage is after I reassemble everything.
