I'll have to pm them to you because I forgot to black out a trademark

I'll include the power and ground distribution,the gauge cluster and computer wiring.
I did some looking on the diagrams and seen that you'll need the computer to make the speedo work. Looked into it a little farther and found out why. The signal from the sensor is analog and the computer converts it to digital then drives the speedo motor.
If you don't want to deal with the computer then I have an idea that may work. If you want to hear it I'll go thru it

The tach will work without the computer,that I've done before. Should be a solid white wire out of the bulk head connector on the driver side that'll be used.
