cig lighter starter disable

[aaron325ix]

I have an alarm, but I'm just thinking of the times when I'm not around to hear it (and run outside w/ my 357mag:D) like at the airport, anywhere really. And cars do get stolen around here. God I fucking hate thieves!

[DaveSmed]

Out of most of the rolling turds that hit the roads in the '80s E30s are by far one of the more theft resistant, and as of late, less desirable theft targets. GM G-bodies (RWD Monte carlos, Cutlasses, and Grand Prix) have enough metal to make 2 E30s and can be stolen by a 10 year old.

Luke, I've had good luck with OEM stuff and industrial grade stuff, but getting it takes some looking as most people just hand you a generic that will "work". Either way, starter kills are easy to bypass, and the first place someone looks to bypass one is above the drivers footwell which is where EVERYONE puts them. Should someone have taken the time to hide it, then jumping the starter or pop starting it gets around it fairly quickly.

Want a little extra theft protection for when you leave the car somewhere unsupervised? Pocket the main relay, or unplug the CPS or something important. If you are set on an electrically controlled countermeasure, cut power to the fuel pumps, DME, etc. Maybe even ground out the coil.

Some company sells solenoid valves you install in your fuel line to cut off the flow to the front of the car to eliminate hotwiring the pumps (which I doubt you'll need to worry about anyway)


SuperDuper, move the wire from the center terminal (87a) to the bottom one (30) and your good. The gray band on the diode does go toward the lighter.

Ok, so back to super dupers idea, does it sound like that would work reliably? maybe have an extra relay handy if it did fail? I dont know, seems like no body is really fired up about it. I just think would be a cool theft deterrant, and mod, ut maybe more trouble than its worth.

If you have to ask how to wire a starter kill of theft deterrent to the point of needing step by step advice and a diagram then this is definitely something you DO NOT want to try yourself .

[aaron325ix]

well shit, I guess I'd better just give up then... I dont recall asking for step by step advice. :bow:

Yea, it would prob work reliably. Cool theft deterrent? No. Cool mod? Subjective, if you like it, by all means go for it and post up a how-to if you are so inclined.

If you are looking for a theft deterrent, look elsewhere as this isn't.

[aaron325ix]

Well, why dont you think it would be a good theft deterrant? especially if I take the lighter with me. Yea they could bump start it, but for what it's worth, iXes are way harder to bump start than normal RWD's trust me on this. but regardless would a crook really think about the lighter? Probably not. I dont know I'm not dead set on it, just thought one more layer of protection would be nice, so long as its not more of a hassle that wht it's worth. Thanks again for your help.

Any form of starter bypass is too easy to circumvent, be it controlled by a switch, alarm system, or even a cigarette lighter.

I read a thread on this recently, but I'm not sure I understood it correctly. What I want to do is make it so that when i get in my car you have to press in the lighter, and then start the car like normal. I dont want the lighter to be a button starter, just a theft deterrant. I mean what dumb ass criminal would think to push in the lighter to start the car? You could also just take out the lighter all together, and there is no way they could start it. Has anyone done this? Thanks.

I bought my car with this little deterrant you are asking about. It's the shit, because everything works except for the starter and I don't smoke so I'm not missing out on anything. I also tried the jump start scenario and trust homie that shit is full proof. Wish I could help with the how to but maybe if you go to an alarm and stereo installation store you could ask (make sure it's not a snotty nose youngster fresh out of diapers who doesn't know what they are doing).

[aaron325ix]

and also, as mentioned before, an e30 isnt worth that much so I doubt any one is going to spend much time trying to figure out why the car isnt starting. Theyd probably figure the battery is dead and then move on. So you say you havent had any problems with yours? Just push in the lighter and start as normal?

Thanks, I'm almost poitive 87 and 87a are continuous with each other. When the relay energizes, 87 is continuous with 30.

Yes, it would be reliable. With the relay at rest, the starter circuit is complete. Only when you energize the relay does the circuit get interrupted. Most relays fail in this regard, they wont energize...

I used to have a circuit similar to this in my old IASCA car. By pushing in the lighter, the rear speakers would turn off for SQ meter testing. For the objective listening portion with the judges, I would just pop the lighter back to its resting position and viola, rear speakers.

ultimate theft deturrant, friends datsun has 4 switches, one controls msd box, one controls megasquirt/one controls lights, one controls fuelpump, then you have to turn the key. =) easiest 5 minute wiring job ive ever done,

[DaveSmed]

Thanks, I'm almost poitive 87 and 87a are continuous with each other. When the relay energizes, 87 is continuous with 30.

Switch around 87 and 30 in your description, and your good. 30 is the one that always connects to something, either 87 or 87a depending on if its energized or not.

[aaron325ix]

so it's cool to follow the diagram above(Super Duper's on first page), only with 87 and 30 switched and I'm good to go?
