Subaru EJ22 kill switch wiring question

[newerwesty1987]

Thanks, but, why not just switch the ground with the switch? The amp load wouldn't be an issue and it would make it more simple.

I just interrupted the ground wiring right at the pump. I used a relay, whose coil used the +12V provided to the pump and was grounded via a simple slide switch, hidden in plain sight once the driver's door is opened.

Easily bypassed if you know how and if either the switch or relay plays up. I doubt a thief would go to the extent of grovelling on the ground and figuring out how to bypass it.

If you want a picture of the switch location, PM me.

I saw the other thread about the transistor possibly being blown. Is there isa safer or more simple wire to make this work just as well? What about just interrupting the ignition/starter relay wire from the key switch itself? The kill switch could be near by under the dash or in the ashtray, etc.. or even use that rear heater fan switch if possible (mine is also removed from under the rear seat)

I've added a "hiding in plain sight" kill switch using the rear blower fan switch but now I'm not getting a ground from the ECU going to the fuel pump relay...

I started a new thread in the hopes that someone out there in The Samba land will have some insight!

Yeah, I'm following this for sure too!

Adam,


You are correct sir, the ground on the fuel pump relay is an easy simple way to immobilize your van. I located the ecu and relays in a small box under the rear seat. There is a small switch inside that kills the fuel pump. The van will turn over like a champ, but will fail to start. In my mind it’s an excellent option because there is no monthly cost and without fuel there’s no question your vans in the same place that you left it. Once the van won’t start there not going to troubleshoot, they might steal your stereo or your tools, but not the van. Very easy to do, solder your connections!

I also have a battery isolator for double protection. This is more for electrical safety, but super easy for theft prevention.
Good luck!

Don't have your answer but....... IMHO....... any wiring you do should maintain the factory look.
Any new wires, any cheapo crimp connectors will just scream "LOOK HERE!! THIS IS WHY IT WON'T START" to any car savy thief.

Even a GPS tracker should be wired totally out of sight and the unit also located out if sight.

On your conversion, do you still have the black box in the LF of the engine compartment?
Do you still use the next black relay box to the rear with the fuel pump relay in it??
If so, I'd work within those boxes for the fuel pump kill.

Hi, I thought I had bookmarked a thread about this previously but I can't find my previous reference.

Anyway, if one were to install a kill switch on the fuel pump relay of an EJ22 converted Vanagon, would the best way be to interrupt the D23 ECU ground to pump relay wire (light green and black wire, I think...)? If I recall correctly, this would be the safest and lowest amp draw wire to choose from. The purpose is to help deter potential theft.

Thanks in advance!
