remote start constant 12v, combine or no?

In answer to the first post, if there's a nice thick fusebox constant feed locally, I'll split between the constant feed at the ignition and that or as in the case of BMWs, 2 thick red primaries feeding the ignition, split the supplies, not talking about 1 US vehicle where one of those is only fused at 10 amps, but again my circuit goes supply wire at least two leads soldered to it then fuses. And of course fuse everything with the exception of Hondas and I know I'm not alone there, stand up Tedmond.

Thanks for the great info guys!! I always enjoy and appreciate your posts.
