So far it works great. This was fairly simple to do, and easier than wiring up that relay starter booster. I figure this way helps compared to stock because it gets rid of alot of connections the power had to transfer through and old longer wiring to get to the starter. I wanted to see if doing this simple wire mod would make the starter work every time, and since it is easier that wiring up a starter booster relay.

Just some 10 gauge wire and 2 wire connectors and wire loom I already had. I already had a hole in the firewall with a rubber grommet for other wires so I easily ran the wire through there. I can easily switch back to how it was before if needed, I didn't cut into any of the stock wiring. See picture, I also wrapped some duct tape around it so it doesn't come loose.

There is a green/yellow wire there, it's probably the one that needs a ground pulse to turn off the factory alarm if using a keyless entry like I am.

Since ~2002 I've had this intermittent problem. Turn the key, get a click and nothing else. Usually have to do that two or three times and then the car will start.

Kind of frustrating, kind of embarrassing, definitely a pain in the ***. I will say the car never left me stranded but the possibility of that bugged me.

So, over the years I replaced many components usually for other reasons but always hoping this problem would be corrected:

*new starter
*new battery/starter/alternator harness
*new ignition switch

The problem still persisted. About a month ago I gave Brent's idea a try, and the car hasn't done it since

Here you can see the oem security relay (H302) that's located behind the kick panel by the dead pedal:



remove it and jumper the two connections that correlate to the thicker wires:





Takes all of ten minutes. Thanks to Tom the Bagelman/Theorie for his assistance. I didnt snap any pics when I did this a month ago so we documented the historic installation on his silver hooptie

The best way is to unplug the gray connector from the hood latch, and jumper the two wires. see pic below. I had it disconnected before but didn't realize I had to jumper the two wires to make this trick work. this way everything else works normal. If you unplug any of those boxes like the green one the alarm won't or may not work but it messes up other stuff, like the passenger power door lock may not lock and unlock when the drivers side does. I tried other stuff too but couldn't get my keyless entry to disable the factory alarm when hitting the unlock button, so the best solution is jumpering the hood latch wires. This sends a ground signal to the alarm module and the alarm thinks the hood is open and it will not arm the alarm when the doors are locked.

Sorry for getting off topic, just had to correct the info.
