DIY: Vtec indicator light

[patofdzb]

Hey well after doing this mod, and seeing some ppl were having problems, i decided to post up this DIY.
I chose to tape instead of soldering becase i dont have a soldering iron, and i would be afraid of belting the Vtec wire

Steps: 20

Time: 10-15 Minutes

Materials:
- 1 Led of your choice
- 1 Resistor ( i used a 330 ohm 1/4 watt)
- 2-5 ft of wire/ speaker cable
- Scissors
- wrench or pliers
- black/electrical tape

Optional Materials:
- Soldering Iron
- Wire Tap-in
- Butt Conectors
- Drill
- Enough gas to go test it
- 6 pack of beer

resistor not shown*

Step 1: Solder/tape led, reistor, and wire.

Step 2: Unplug your battery, just in case.

Step 3: Mount your led wherever you want

Step 4: Pull the carpet back from the Paaengers left foot

Step 5: Locate the ECU.

Step 6: Unplug 3 of the connectors.

Step 7: Cut the HUGE zip tie so you can pull the wires closer to you.

Step 8: Take the black tape off of the Big grey connector

Step 9: Locate the Vtec wire
WARNING there are 2 green and yellow wires on that same connector
green with a yellow stripe ( vtec wire )
yellow with a green stripe (not vtec)

Step 10: Splice the vtec wire, and attach the wire to the led.

Step 11: Tape/Solder both wires together

Step 12: Tape all of the wires from that connector together;

Step 13: Plug back in all 3 connectors on to the ECU.

Step 14: Put the carpet back on, and dont forget this little guy.

Step 15: Now choose a ground point, run the wire, and ground it.
I chose the seat bracket.

Step 16: Put up all the mess you've made.

Step 17: Give yourself a pat on the back for doin a good job.

Step 18: Get in the car and turn on the engine.

Step 19: Test it!

Step 20: If it works, then your done!

very good write up. great job with the wiring section.

if you don't mind i'll link some of my info.

mostly just shows where i mount the light.

and here's a few vids i made to show where vtec actually engages:

0-60 vtec (engaged throughout)

2nd gear, late vtec (~3800rpms)

1st, 2nd, 3rd, 4th vtec (as low as ~2300rpms)

1 wire from led to ecu, the othe from led to ground?

also where you put the resistor(s)

 

[dynasty]

resistor should be on the positive wire which is from the LED to resistor to VTEC wire.

 

[patofdzb]

yes 1 wire from led(+) to ecu
and 1 wire from led (-) to ground,

the resistor goes on the positive side of the led, which is the longer one

EDIT: Heres a diagram on how it goes.

Seems easy enough..what is a resistor? xluben said the one he bought from radioshack came w/ the resister presoldered?

resistor is like a small chip that "resist" energy flow into either LED, or other sort of machinery. basically what it does is, it balance the energy (volts) from the battery to your LED from overloading.

not really sure what it is, but i think it regulates how much voltage, etc goes trough.
