86 cluster wiring diagram needed!!!!!

Car is a 1986 ford thunderbird base model that came with a 3.8l v6 and has the all digital cluster.

I need a wiring diagram, or any info, regarding the 2 connectors that plug into the cluster.

I need to know which one of the wires is the "signal" wire from the fuel level sender so i can hook it up to my new gauges.

Also knowing which one is the speedometer "signal" wire would be a huge help.

Bonus questions:

What signal are our fuel level senders? is it 73-10 or 20-150 ohms?

Is the speed sensor a hall effect 3 wire or a sine wave 2 wire sender? pulse amount would be nice too.

Thanks everyone for any help!

Wiring info here (click on the cluster type):

Our fuel level senders should be 73-10 Ohms.

I'm not sure about the speed sensor. I remember going through that when buying an aftermarket fuel gauge…something nags at me that it's the sine wave but not positive. Bought the fuel gauge, hooked it up, works fine. :)

Speed sensor is 2 wire sine sender (AC generator). Both fuel and temperature senders are approx. 100 - 10 Ohms (oil pressure sender for buttstuffog cluster too).

Hey guys, thanks so much for all the help! Installation was a snap! Prototype cluster went in great. Hopefully be able to optimize design and get it up on this site in the vendors section.
