It is important to note you make these changes at your own risk. I provide this as demonstration purposes only.

JLWoodward, can you draw a schematic of what you changed?

(oops... I see that you did already...I saw it there AFTER I registered.)

Where did you get your relays?

Would this do? How do you tell which points are 30, 85, 86, 87 ???

Or do I need a 5 pin?

I bet Roadmaster would tell you if you called them.

Either of those relays will work Elvis, happy travels
