Need Some Cruise Control Info Please

[Blue85]

I'm currently swapping a cruise setup from a 77 blazer to my 72 chevy truck, like a moron i cut the green resistance wire (before i knew what it was) that goes from the transducer to the turn signal switch. So i'm wondering if someone can tell me how much resistance this wire should have. In the 67-72 service manual it says the wire should have 40 ohms end to end, both ends unplugged, and between 42-49 ohms from the signal swith connector end to ground, when the transducer is connected. If someone has a service manual for a mid 70's truck i'm thinkin it should be in there, Thanks
