First off, I want to give credit to Scott (Texas Outlaw) and Marv (SpringerPop) which is where I got this idea from in the first place. The first Theft Deterrent Thread hit home for several people, but they didn't know where to start and didn't want it complicated. No offense Marv, your design is brilliant!
The idea of having to pull off the fuse dash panel and then the fuse box cover to remove Relay 303 (Injector Drive Module Relay) is a little inconvienent to say the least. Especially, if your like me and want to disable your truck everytime you shut it off. Here is an idea that I just tested, its simple, its cheap, its reversable, and it works.
This Mod reqires removing Relay 303 and relocating it just outside of the fuse box and installing a toggle switch for interupting the relays ground connection to the fuse box.
You will need:
-5 male crimp-on blade connectors
-7 insulated female crimp-on blade connectors
-1 toggle switch (choose your style)
-At least 8 feet of 18 guage wire, or more depending on where you plan on mounting your toggle switch.
-1 small zip tie

-Cut 4 pieces of wire 12 inches long, crimp a male blade connector and a female blade connector on each end of the 4 wires.
-Locate the numbers on the relay near the blades, connect the 4 wires to the 30,87,87a,85 terminals.
-Attach the other ends of the 4 wires to the corresponding blade recepticals in the fuse box, where relay 303 was originally.
-Locate your secret toggle switch location, cut a wire long enough to reach from the toggle switch to the relay, crimp a female blade connector on each end of the wire.
-Attach one end of the wire to the toggle switch and the other end to terminal 86 on the relay.
-Cut another piece of wire long enough to go from the fuse box to the toggle switch, crimp a male blade connector on one end of the wire and a female connector on the other end.
-Attach one end to the toggle switch and the other end to the remaining open blade receptical that blade 86 would plug into on the fuse panel.
-Carefully route the five wires toward the right of the fuse box and reinstall the fuse box cover, the fuse box cover may need to be notched to ensure the wires are not pinched when latched.
-Zip tie the relay to a desired location.
-Test
The first pic is a small version that I made to test with, you should get the idea though. The second pic is of a 2002 fuse panel indicating the location of Relay 303. I made this detailed so anyone could attempt this Mod no matter what their electrical skills may be. Hopefully this helps you guys! Good Luck!

 

Chris, that is cool. a lot more work than using a toggle switch to the started solenoid, but just as effective. i hope you are like me and solder everything. I do not trust scotch locks or crimp connects.

where we got sidetracked on the last thread was the idea of making it automatic with the FOB. Like Lisa said, the one time you forget it....

 

this is a really good idea, following the previous thread. It may be worth a try with teh switch in a conspicuos area

 

Nice write-up! Thanks for your work. I'm going to do your method or the pass side starter selenoid method. FTE guys are the best...

 

Rampage- reps sent. Great idea, I have a toggle switch in my toolbox and I'm strongly considering doing this just to be safe (not a huge theft problem where we live, but what happens when you go somewhere else?) I've got a notion, though it would take a bit of wire, to mount the switch in the ash tray somehow (I don't use it for anything else!)

 

Chris -Great write up. Thanks. Will be doing this mod this weekend.

 

Just a thought - Could you put a switch in the fuel pump ground wire?

 

You could, but the truck might run a little on whats left in the fuel rails and end up sucking air into the lines (bad for the injectors). This method keeps the injectors from firing.

Chris, nice write up. Reps on the way.

 

That's nice, effective, and simple to construct, too!

Nicely done, Chris!

 

Chris!

Perfect, I now have this weekend's mod.

I tried to send you rep but I have to spread it around.

Thank you!

 

very good idea Chris...wish i could rep you to.but need to spread them around first....ill just give you this mod trophy

 

Great job on the write up. Rep points given.

Just a note to others thinking of doing this. Double check the location of your IDM relay as it may change on different year models.

 

That's pretty awesome not gonna lie. Ugh nooo i don't need another swithc in the cab

 

Thanks for the kind words guys. I forgot to mention that SpringerPop's 2000 model truck has the IDM relay under the hood so this procedure will be a little different for those who have a 1999 and 2000 year model truck. I'm not sure about the location of the IDM in 2001 trucks. I just hope this helps out those guys who are squeemish about cutting and splicing wires in their truck...and its totally reversible.
On a side note, I like the fob idea of activating the relay but couldn't think of an uncomplicated way of doing it.
Like I said before, I wanted to present this as cheap and easy as I possibly could.
