If your happy, that's all that counts. You now have two switches to go bad, more wiring, more terminations, don't see a ballast bypass, and still have to foot start and also hand start after turning on a key. Modern it ain't. Better it ain't, more reliable it ain't. Very innovative. Shows you are energetic. Sounds like you have a fun job at the Limo place. You have not offended anyone by not asking. We were just having fun with ourselves. You are good to go, looks like.
BTW: There are three types of Solenoids used in the vehicles we have on here. The one you show is a switching solenoid, used to make contact with large volt/amp circuits, second is an electro magnetic solenoid mounted on top of a starter, self contained switch with a return spring inside. That one moves a lever which has a drive gear and at the same time makes electrical contact and spins the starter. The third one is the foot starter where your foot operates a lever which has a drive gear that engages the flywheel and makes electrical contact (foot switch) at the same time, as you now know. Sometimes the first two are used together. In your pic, I don't see the return spring. Did you reinstall it?
