Members have used both setups for the starter...I guess it does depend on where you are going with the truck long term...you mentioned looking at a painless harness...if you are going to do a bunch of wiring, you can easily go either way on the starter switch.
Whether you want to keep the stock look or not is a key decision to make...maybe not if the wiring is bad and will be modernized but I dont know your details...
Guess it would help to know your plans for the truck and its current state...
People have bought different painless harnesses and made them work...I think the 8 circuit is enough to make things work...going to a 12 is plenty for a stock truck with a few extras...
Lord send your Holy Ghost into our hearts and make the desire of our hearts Your Will.
