1992 trx 300 2wd new owner

Just got a 1992 trx 300 2wd for free, last person that worked on it butchered the wiring harness, don’t even know if it ran before they went crazy with dykes and twisting wires, so with any luck maybe with all this experience here i’ll be able to get her running. got the new wiring harness in and new switch assembly, guess my first question would be, since it has a kickstart does it matter if the run switch is on? any advice on this bad boy feel free to holler at me.
