Yep great idea Bob. Start from the beginning... I'll do the wires from the battery terminals first. As for fuses, what sizes Should I use. Also what gauge wires for the rest so the harness if possible? Sorry for the mundane questions in advance... After mastering the crimp tool fixing some switch wires on another bike I'm fairly certain this will go well!
As for the idiot lights... Somehow I missed your pic with the drawn in circles.... So I tried that layout with everything connected. You're right. It gets tight towards the front (my layout won't work). Also you have a circle directly behind the hole dead center in front of the light switch knob. There isn't enough room for both lights and the switch knob. So I've opted to go for 3 idiot light option and forgo the brights idiot light as you suggested earlier. The one that is already drilled front center (using the light from the white bulb holder)and your 2 lateral rear orientated ones are what I'm going with. I like it less busy anyhow.
My pantah is singing a great tune so it's time to turn to the single harness! Incidentally, my friend and I picked up an 85 allazzurra for next to nothing because it wasn't running. I redid some wiring and that is running so well. Reading all the posts here and and all the studying for the single wiring has given me a sound basic approach to motorcycle electrics!! It's too cool. Reading all your advice/posts has really helped. I've learned how there are some pretty simple solutions to what looks like complex problems. Thx rob

____ It seems one of us hasn't got very-good memory, as I thought we've already covered these details once before, (as I thought it was you who had gone-ahead & ordered some varied selection of fuses already, quite some time ago).
__ Anyhow, any fuse-values rated near-around half the rated-value of the main-fuse, would do well enough (for the rest of the circuit-fuses).
The 'main-fuse' ought be between 20 to 30-amps.
__ And as for wiring-size, 16-gauge is the most suitable wire-size for most-all the main wiring-lengths. _ However the tail-light wire (and any other low current demanding wire-circuits) ought be no heavier than 18-gauge, and the pilot-lamps could easily get-by with far slimmer-yet gauged wire-leads !
__ If you don't happen to already have a short length of the suggested green-colored 14-gauge wire, then a short -(2 ~ 4 inch) length of 16-gauge for spanning between the battery's neg.terminal-post and the fuse-holder would be good-enough for that minimal length. _ Then from the outlet of the fuse-holder, you could connect two lengths of 16-gauge green-wire,, one to normally connect to the stock grounding-point (under the seat), and the other additional-length to span the distance (from the fuse-holder) up-to the headlamp-shell. - (The non-stock/additional length of ground-wiring is intended to better address the concern of keeping the headlamp fully grounded [for the sake of headlight-efficiency].)
Also, be certain to avoid any use of cheaper wiring which only contains a relatively sparse number of individual wire-strands within it's sheath-jacketing. _ (I understand that 'aircraft-wiring' has the best flexibility [in regards to such strand-fineness/quantity concerns].)

____ You really shouldn't have missed that before ! ...
I began construction of that picture after my post became posted on June-9th, and well recall that I finally got it included into that post within the same hours-time after Graeme had gotten his-post posted !
So when you placed your post the next-day afterwards, (on the 10th),, my example-picture (of your headlamp) was by then already posted for previous viewing for near-around 21-hours prior (to the post-time of your first following post).
And also, you had then seemed to've acknowledged the fact as well, with your stated-wording: "Yep you guys are right".
So it would seem that you've rather just forgotten you had previously seen that picture back on June-10th,, or-else you then hadn't yet bothered to look at an expanded-view that makes the added black-circles more visible & notable, (which is more likely the probable case).
" you have a circle directly behind the hole dead center in front of the light switch knob. There isn't enough room for both lights and the switch knob. So I've opted to go for 3 idiot light option and forgo the brights idiot light "
____ That's too-bad. _ I myself would find an alternate location (even-though it'd have-to be off-set someplace else), as I've always tended to prefer excessive 'bells & whistles',, but I certainly understand anyone not caring to do-so, (and avoid any such resulting asymmetry).
" The one that is already drilled front center (using the light from the white bulb holder)and your 2 lateral rear orientated ones are what I'm going with. "
____ Okay,, providing there's no resulting fitment-interference, that's probably good enough.
__ However that parking-light indicator is relatively dim to see very well with the stock 3-watt parking-light tube-bulb, so you really ought consider rather employing a 10w.version instead !
Hopeful-Cheers,

Re: 1965 ducati narrow case
Yep I have all the colors in 16 and 18 gauge! I did not know about the 14 gauge but I got it! I have a several inline fuses. I just wasn't sure what their gauges their wires are. I'm pretty sure they are not 14 gauge. So I was thinking of getting one with 14 gauge for the negative terminal ground. I will wire up the ground to the headlight as you suggest I understand the efficiency point you make.
I know! Not sure how I missed that diagram it's really good, and with all the switches on it fits perfectly. I will go back and find another spot for the 4th light as you suggest and use the 10 watt bulb. Yep I failed to look at the expanded view. I meant you guys were right about assembling the switches and then seeing where the lights could fit. My original idea was inadequate when it was all assembled. Thx again R
