Identify these two wires under the dash and help me hook up my cab lights - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Fellas,

I have three questions concerning the wiring on my truck...

1) I'm using an 87 model donor truck for the wiring. I've got it all swapped over to my early cab and am finishing up with the details. What are these two wires hanging under the fuse box ? They are black and white.

2) How did GM tap the cab light power wire into the electrical system ? I know there are many places to hook my cab lights up to the light wiring harness, but I want to do it exactly like GM would have done on a truck with factory cab lights.

3) My 87 donor harness has pulse wipers with the module, but my 85 model steering column didn't have delay wipers. The wiring all plugs in easy enough. What will I need to do to convert the 85 column to operate the pulse feature ? Is it just swapping the turn signal stalk or what ?
