I can't take credit for this. Dan Langhout posted it back in 2011 but I can't find it. Thank goodness I saved a pdf copy.
These are the fittings I found worked best.
Aluminum will certainly work. Lighter and cheaper but steel fittings are recommended FWF and the wholenidea is a fireproof penetration. You may consider some 3M 2000 inside the fitting before locking it down. The cable in the photo is actually passing through backwards. You'll figure it out.
AN819-4 AN FITTING
AN832-4 STEEL FLARED UNION
AN818-4 STEEL NUT
AN924-4 Steel AN Fitting
3/16" or 1/4" Brass Ferrule
Stainless washers
I bought stainless washers and used a step drill to increase the hole diameter. 7/16" for AN4 fittings.
Measure your cable first.
The smaller push-pull Bowden cable...
Drill the fitting with a #13 drill then a #12 reamer. Use the 3/16" ferrule.
Larger Bowden cable, use the 1/4" ferrule
