New Engine and 3 Speep Wiper motor Harness, extra wires?

[mpro69rr]

Hey Guys,

69 RR 383 4 speed. I installed a new engine harness and new 3 speed wiper motor. On the first picture the wiper harness came with an extra wire hanging off the bulk head plug, does anyone know what this is, I couldn't find it on the wiring diagram? The second picture is the new engine harness before the voltage regulator right behind the engine, its a grey wire with a spade connector on it, anyone know what this one is? Thanks!

Is where the transmission reverse light switch harness plugs in. The other wire is your oil pressure sender wire..

Grey goes to the oil pressure sender.

Thanks again DadsBee! Looks like I don't need to use the oil pressure one, I have another oil gauge and I'll have to look into the transmission reverse light one.
