Crank signal C9 Most scouts have a large white wire going from the ign sw to the S terminal of the starter. This is the one you want to tap into. I used a simple scotch lock but you can also run it to the starter and hook it right to the S terminal of the starter. Fuel pump I had already ran a wire to the pump so I just spliced it to the open wire coming from the fuel pump relay B2. TPS I have 2 different styles. The round later style and the earlier flat one. For this vehicle I will use the flat one. If you are running the VSS then there will be 2 wires coming from it. 1 goes to ground. The other goes to A10. I also have an aftermarket cruise control so I splice it in to the VSS also. And the main power wire goes the main starter terminal. So what does spaghetti look like on a motor???? So now lets hook it all together and see if it works!!! You need a cable to log the data. you can build your own with the instructions provided or You can now buy a direct USB cable from me for $30. See the machine shop forum under Hamilton fuel injection. It plugs directly into your usb port and connects directly to the ALDL connector on the harness. No adapter needed. Looking good!!! Note the green 20!!! Still have some cleaning up to do and put the wire loom back on and splice the ALDL connector and SES light in!!
