Ignition switch wireing.
Hey guys I'm new to the forum. Had a quick quesiton. I recently cliped all my wires to the ignition switch on top of the steering column... the switch that the actual key controls.
My plan is to relocate the new switch that I have into the center console along with a push button for the start. I just wanted to double check to be sure I got all the wireing corect. Please correct me if i'm wrong.
The Trans Am is a 87' 305 inj w/ 5 spd trany
Red (2) --- Obviously power wires hooked up to batt terminal on the switch
Yellow-- i believe will go to the starter which means the push button
Pink-- I believe is the ignition wire and will go to the ignition terminal on the new switch
Orange-- Not 100% sure, but possibly an accessory wire for the (heater blower) that will be connected to the accessory terminal on the switch.
Brown (small gauge wire-- Not 100% sure but possibly another accessory wire that would hookup to the accessory terminal on the switch.
Green (2 small gauge wires that were already to one post on the origional swich)----- I'm not exactly sure on these wires, but possibly another accessory wire that will go to the accessory terminal on the new switch.
Guys any help on this would be greatly appreciated.

Pink = run ignition to coil
Brown = accy/run to radio
Orange = run to heater
Yellow = starter
Red power to fusible link
I'll study this out for those green wires Hard to follow these diagrams for this year.

Looks like the small green wire circuit 35 is grounded on start to test the coolant dash light. Might be a small tan wire that is also grounded on start for the brake dash light, circuit 33.
