For the FI kill-switch build, a friend convinced me of the value of
this design for a fifth generation civic, which interrupts the ground to the injector relay. THE ADVANTAGE of this design is that there will not be a large electrical current running through the switch and its leads, which run along the metal shifter rod.
NOTE: For the sixth generation civics (1996-2000) the fuel injector relay was moved to the passenger side dash, behind the glove box, beside the door. In the fifth generation civics (92-95) this relay was beside the fuse box under the dash on the driver's side. It is harder to get at in the sixth gen arrangement. Here's a pic of the FI-relay as installed behind the glovebox:
Here is what you need for this kill switch:
1 - A non-lighting interrupter switch (push to break the circuit).
2 - 5+ feet of 18 gauge wire (black preferably).
3 - At least four butt-splice fittings.
4 - An OEM Sixth Gen auto trans gear selector.
5 - TOOLS: phillips head screw driver, wire clippers, 10mm socket.
Here is the basics of what you do (see pics):
1 - Remove the glove box
2 - Identify the injector relay
3 - Remove side panel to get at 10mm bolt securing relay
4 - Cut back conduit and clip black ground wire one inch from plug
5 - Strip ground wires both ends and attach butt-splices
6 - Attach your wire to the splices to make a long ground wire extension.
7 - Attach wires to switch (we had to solder, but you may find easier switches) and insert wires and switch into shifter knob.
8 - Securely mount the shifter knob to the shifter, wires running on the inside, down the shifter and under the pleather decorative thing.
9 - Attach switch wires to extended ground wires using a second pair of butt-splicers.
PS: in the final install, I went with a black button. Stealthier. That's why the color changes in the pics.
PPS: Special thanks to my friend BG.
