You can use the white wire going into the #10 pin on the lower harness plugging into the ecm. Pull the cover off of the lower connector, you will be able to see the numbers. Just splice into that wire and run the wire through the firewall using the hole already there behind the computer. It will have a grommet with some wires already running through it, so you can just make a small slit into the grommet and run the wire through the hole and under your dash. Hope this helps out.

make sure you have the rpm activated module set to 4cyl. If it is on 8, it will not work properly.

If its wired in correctly, then that will be your fix. I forgot exactly why you have to put them on 4cyl.
