First, I prepped the two modules to get them ready for install. I used my electric drill to twist the blue (Lock output) and green (unlock output) wires together on the auto lock module. I did this because the lock and unlock wires are in the same harness, so it will keep things a little more organized.
I then soldered the short red wire to the long red wire, since I want the module to operate in instant trigger mode. If you need the module to work in 6 second time delay mode do NOT hook these two wires together.
Next, I connected the black (ground) wire from the speed switch to the black (ground) wire from the auto lock module. Both modules will be grounded at the same point, so I tied them together.
I then connected the orange (Switch output) wire from the speed switch to the yellow (ignition input) wire of the auto lock module.
Finally, I soldered in a programming switch. This isn't 100% necesarry, as once the module is programmed one it should never need to be programmed again so the switch does not have to be permanent. I chose to permanently install it so that I can test the module out easier over the next few months (this is my fiance's car). I connected one side of the normally open momentary pushbutton to ground and the other side to the purple wire of the speed switch.
After all my prewiring I was left with 6 wires:
Red: 12VDC
Yellow: Ignition
Black: Ground
Blue: Lock
Green: Unlock
Blue: Speed Sense Signal
I mounted the modules in an open spot on the right side of the drivers side under dash (near the center console). I wire tied the modules to a bundle of wires there to keep them from rattling. I routed the black, yellow, green, blue, and red wires towards the steering wheel. The door lock wires are easily acessible so I did them first.
LOCK: pink/black at MICU (fuse box)
UNLOCK: pink/blue at MICU (fuse box)
Since the remote start included keyless entry there were already connections made to these wires. I simply tapped the remote start wires. Green (Unlock) from the KPtech auto lock module would connect to the pink/blue wire in the car, and blue (Lock) would connect to pink/black.
Next, I went for the 12vdc and ignition signals. There is a big loom of wires running up to the steering colum. Inside the loom you will find the 12vdc and ignition signals. Once again, since the remote start already tapped these signals I just used the remote start wiring. Also, I installed the supplied fuse in between the KPtech Red (12vdc) wire and the Honda 12vdc wire.
12vdc: White (big loom going up to steering column)
Ignition: Black/Yellow (big loom going up to steering column)
For the black (ground) wire I crimped a ring connector on to the end of the wire and used a self tapping screw to attach the ring connector to the metal underdash. The Honda provides several good grounding points, as most of the underdash is metal.
Finally, I located the vehicles VSS (vehicle speed sensor) wire.
VSS: Blue/White - PCM on top of transmission tunnel, behind center console, access from passenger side.
To measure a VSS wire you need a meter that will read frequency. I used my low end Craftsman meter (Sears, $30) to verify this wire. The particular Craftsman meter is capable of reading Hz, so I attached the black lead to ground and the red wire to the first blue/white wire I found at the PCM. I set the meter to DC Hz and I drove the car up and down the street. The frequency reported changed directly based on speed, so I was confident that I had the right wire. I connected the blue wire from the speed switch module to this wire.
Up next was programming the speed at which the doors locked. I started the car and drove down the street. I believe the doors locked at around 20mph. I was looking for 10mph. With the doors locked I pushed and held down the programming button. The doors immediately unlocked. After five seconds of holding the programming button down the doors locked back (this indicates programming mode has been entered) and I released the programming button. I accelerated the car to 10mph and then pushed and released the programming button again. I stopped the car, shut the ignition off, and then restarted the car. I drove down the street again and right when I hit 10mph the doors locked! I stopped, shut the car off and the doors unlocked!
Total install time was about 60 mintues from start to finish. For your first one I would guess the install would take about 120 mintues from start to finish.
