When I unplug my stock cluster it killed everything. How did you get around this issue? Any help with this would be appreciated. Thanks
Also, I'm using my gps as a speedometer.
Just to be clear when I did my conversion I did away with the computer completely.
I made the dash panel myself, I used a plastic air conditioner baffle laminated to some 1/8" plywood. I used leds for the turn signals and brights indicator (o'reilys). The fuel gauge was a little tricky as the factory gauge is a 240 full/ 33 empty sending unit. Use a 220/20 gauge and just put a 20 ohm resistor in line or use a rheostat with 20 ohm in its range(radio shack). Volt meter is easy just wire to a switched 12 volt. Oil pressure will connect right next to the distributor (towards the drivers side) on the back of the motor. There should be a place on the side of the head on the drivers side right behind #1 cylinder for the water temp, or on the front of the intake somewhere. As far as speedometer gos I went with a speedhut gps speedo works great. As far as AC I really cant help with that.
When you take out the stock instrument cluster there are 2 plugs. Here is the colors you need.
Dark blue/White=Hot Switched
Along the drivers side frame rail(next to fuel lines)
From the fuel sending unit
Brown/Yellow=I grounded this one
Dark blue/Light green=to fuel gauge
Dark green/White=is the positive to fuel pump.
Black=ground for fuel pump
As far as making the dash panel I made a cardboard template to make sure all of the gauges would fit. The completed cluster is screwed to the dash trim from the front, you can see in the forum pics. I used a aftermarket tach which is bolted to the change tray in the top center of the dash.
Hope that helps....
