I think it will be ok to reach except for positioning my self to get wires off!! It is quite a mess under my dash. I took off some tape to figure out where my starter wire was going. There should be 3 wires on the one side of ammeter but I was able to follow starter wire which is by itself. I’m just adding horn wire now but there 4 red connected together by light switch. That’s another day.
