Pickup ignition switch wiring

[Lewis-mack]

Hello wondering if anyone can help. Have converted my pickup to a ATD pd engine and have it running and on the road but currently have 2 keys to get it going. I'm trying to get it to start off the original ignition swith. I have the wiring diagram for the pd loom but can't work out the pickup side there is a yellow wire and the 2 white wires(to the same pin) which both get there power when cranking can anyone tell me what they feed obviously one goes to starter but other 2?

 

Thanks

That's great terminal 15 is my starter wire. Do you know what the 2 white wires going to terminal 16 are?

According to the picture shared by ricardo, there is white cable for brake fluid control
