I'm hooking up remote start. Where is the best place to hook up the spark/tach sense wire? Also where can I find the relays for the door locks and trunk release?

To find the relays, press lock repeatedly and follow the sound of the clicking relay. I can't remember specifically where it is. Could be drivers side under dash or passenger behind glove box. There is no trunk relay.

Also the chart i have says white and black for locks but I think it might be white and blue.

There should be a black harness in the drivers kick pannel. In the harness you will notice that the lt. blue unlock wire will change to black on the other side of the harness. The white will stay constant. You can tap this wire at either side of this harness. You do not need to go to the relay to grab these wires. Make sure to verify your wires with a digital multi meter.
