adding a wire for my electric choke.

Hi Y'all,

I am in the process of modifying my engine compartment harness to add in an 8 gage wire for my denso 50A alternator, finish my ammeter bypass circuit on the engine side, etc.

2 questions, My new alternator being an internally regulated denso type, i bought a denso style plug to wire it in. This plug has 14G wire pigtails for the ignition exciter. My ignition feed wire in the harness is 16G wire. Since i havent wrapped up my wiring yet should i upgrade this alternator sense lead in the harness to the heavier 14 gage.?

My second question is, can i tap off this ignition switched hot lead that goes to the alternator to run an electric choke, or will this cause a problem with the alternators internal voltage regulator??

Thanks
Matt
