Hi, not sure if this is the right forum, but new to OCC and would like some help.

I'm repowering a IHC 782 from a KT17 Series 1 to a Mag18. My serial number is 20150594U686135. The engine swap went in fine.

I need help with the wiring harness. The ignition switch is a 725-3026 and the KT17 had two wires, one to the coil and the other to the voltage regulator.

From the old harness I can connect to the middle wire of the voltage regulator.

But, I think I need to install a relay from the ignition switch to the ignition module.
I also have a green oil pressure sensor on the engine.

Here's a couple questions for those of you who have done this that perhaps can help;
1) What type and part number do I need for a relay?
2) can I use my existing ignition switch?
3) is it ok to leave the oil pressure sensor unconnected?

Thanks, Bill
