Still Have a Few Questions About The Wiring

Okay, so now I understand the concept of wiring in a relay. My only other question is are there different relays as far as amps ? Like fuses ? If there are different types what would I need for a starter ? I mean amps ? A five wire relay would have two from the micro switch, in and out for the starter and a ground ?
I cleaned up the grounds for the lights last night and I have the directional arrow issue fixed.

You need to put a meter on the shifter switch to see how it works (or consult the destructions that came with it). I didn't catch what you're working with.
On the relay: pins 85 & 86 are the trigger (coil). They have to be opposing polarity, so if you have a ground coming from the shifter switch, the opposite side gets voltage (ignition on through crank- pink wire). If you have 2 terminals on the switch, ground one and take the other to the relay. If there is only 1 terminal, it probably grounds through the shifter body. Hopefully, to make things easy, it will show ground when in neutral and park. Otherwise, we'll have to modify the current plan- no big deal.
Pins 30, 87a, and 87 are the switch. 87 & 87a are your normally closed section. In this case, we don't need 87a. 30 & 87 are normally open; these will be the 2 sides of your cut starter wire (purple).
So, the way it works is: if the shifter is in P or N, the shifter switch will provide ground to 1 side of the relay coil. When you turn the key on (& to start position), the other side of the coil gets voltage which closes the switch in the relay across 30 & 87 completing the start circuit.

So a 30 amp relay is all I need. I'll check the local NAPA and if they dont have one I'll order one from Amazon. I just placed an order for a few more colors of 18GA wire. I hate having everything done in one or two colors so its going to be a few days before I start working on this again.
Thanks for all your help ! Youre a wealth of information !!!!!
No problem. If you want one through a parts store, they're the same as a Ford Mustang or Ranger fuel pump relay. Aftermarket offers the plug-in sockets; that's why I like'm.
I looked at some of them online. It looks like most come with a plug thats prewired with 14GA. Ive got 12GA running from the bulkhead connector to the starter. Do they make them with heavier gauge wire ?
I just found a relay from Painless thats made for starters. Calling them tomorrow to get info
