HKS Type 1 U.S Spec Turbo Timer Install
To install this turbo timer you must splice into the main ignition harness. It's best to buy a wiring harness for the timer because it will make installation easier along with removal. I bought my harness for $15 from Slow Boy Racing. The timer must also be wired up to the parking brake switch since the parking brake has to be set for the timer to function. The HKS Type 1 also utilizes functions like speed and rpm display along with 1/4 mile, 1/8 mile, 0-60mph, and 60ft estimates. To do this the timer needs a speed and RPM signal which can be retrieved by splicing into the ECU. After all that you ground it and hook everything up and you're good to go. I did this install on a 1990 Plymouth Laser and I'm not responsible if you blow you car or yourself up in the process ;-)
1. Start but removing the negative terminal from the battery.
2. Remove the lower dash covering below the steering wheel. 4 screws hold this on, 2 of which are hidden behind plastic tabs which can be popped off with a flat blade screw driver. Also remove the hood release latch. There are two screws holding it on then you can pop the cable off the latch. This will give you more room to work with the dash piece out of the car.
3. Remove the two black air ducts. There is one screw per air duct on the left side and then they just slide right out.
4. Locate the ignition harness which is above where the air ducts would have been. You may have to pull down the wires some to get to it. Disconnect it and connect your HKS wiring harness to it.
5. Now you must splice into the parking brake sensor wire. Start by removing your shift knob by unscrewing it. Then pull out the ash tray and remove the screw below it. Remove the trim piece between the shifter and the radio (where the center console goes from horizontal to vertical). The two outer screws need to be removed. Now slowly lift the console out while doing so disconnect the two wires from the cigarette lighter and remove the lights from the cigarette light and the ash tray (the entire light socket will come out with a 90 degree twist).
6. Locate the parking brake sensor wire. It's green with a red strip and next to the parking brake (duh!). Splice into this wire by shaving off 1-2cm of insulation with an xacto knife. Strip the end of the gray wire provided with the HKS Timer and wrap it around the exposed wire. Solder the connection and then cover it with electrical tape.
7. The HKS Turbo Timer also utilizes functions which need an RPM and speed signal from the car so you must splice into the RPM and speed signal wires at the ECU. Start by popping of the beezel around the radio. Then remove the 4 screws at each corner of the radio. Now remove the radio by lifting it straight up while holding it flat and then pull towards you. As you're pulling it out disconnect anything connected to it holding it in the car. I had to disconnect three wiring harnesses, the antenna, and another cable connection. The radio will then pull out of the car.
8. Pull off the carpeting on the sides of the lower center console. On the driver's side there are two plastic circle tabs. Pop them off with a screw driver and remove the two screws holding the carpet in place. Remove the carpet. Do the same on the passenger side except there are three screws and the carpet will not be completely removed, but it will allow you to peel it back for enough room to work. The ECU is positioned in a vertical manner and two bolts on the driver side hold it in position and one bolt on the passenger side. Remove the three bolts which are 10mm. Now work the ECU out of it's location and disconnect the three wiring harnesses. You can take the ECU out by sliding it out the passenger side where you peeled back the carpet. On the drivers side you can pull the three harnesses through to give you room to work on splicing wires.
9. Now it's time to splice into the speed and rpm signal wires. Consult the PIN location provided in the instructions of the turbo timer to determine the correct wires to splice into or look at the diagram below (credit for the ECU diagram goes to Tom Stangl, I added the wiring in of course).. For the RPM Signal wire it was 4 pins from the right on the bottom row. This ended up being a black wire on the harness. Splice the brown wire included with the timer into the black wire. Then count 7 pins from the right and this is the speed signal wire which is yellow with a white stripe and also on the bottom row. Splice the blue wire into this. Solder everything and cover with electrical tape.
*If you have a 2g use the ECU diagram included the the instructions or cunsult the ECU Pin List at Vfaq.com
10. Now it's just a matter of running the wires to where you're mounting the timer. You must also ground the timer. The ground is the last wire left over and can be grounded anyone on the vehicle's body. Try to find a non painted surface, if needed sand some paint off. I grounded the timer at the lower ECU bracket bolt on the driver's side. Then put all the panels back on in reverse order. Also connect the parking brake, rpm signal, and speed signal wires to the Turbo Timer by matching up the colors and firmly pressing them together. Hook up the battery and check to see that everything work.
